Who were the hermits in Japan's Warring States period?

Japan's 15th - 16th century, more than a hundred years, a group of rulers, the shogunate rule in name only, the original central government ruling force is not strong in the Iga region at a time there are dozens of forces, have revolted and attacked each other, due to the forces of the land and military strength is limited, and therefore rely on the cultivation of "agents" - "ninja", scouting, sneak attack, assassination and other activities. As the forces had limited land and military strength, they relied on the training of "agents" - "ninjas" - to carry out reconnaissance, sneak attacks, assassinations and other activities, and soon more than 30 schools of ninjas sprang up in Japan, with the Iga and Koga streams being the most famous.

The "Heritage Museum" in Ueno Ninja Village unveils the mystery of the ninja's daily life and practice through documents and objects. "In addition to martial arts, there were also five compulsory subjects: food, incense, medicine, gas, and body, commonly known as the "Five Paths of the Ninja".

"Food" refers to the ninja's recipes. In order to travel lightly on the roofs of trees and branches, and to achieve excellent lightness, qualified ninjas generally weighed no more than 60 kilograms, and their three meals a day were based on black rice, oatmeal, tofu, and grated taro, but on the other hand, in order to maintain full physical strength, sesame seeds, pine nuts, brown sugar, and quail were used. Foods rich in protein, iron and vitamins are also indispensable. This recipe coincides with the "low-calorie, high-nutrition" advocated by modern life.

"Fragrance" means that ninjas can judge each other's economic situation and status by the smell on their clothes. But in order to conceal their identity as ninjas, ninjas often used seven types of transformations, including merchants, practitioners and monks, and spices such as cloves, sandalwood and cinnamon, which are on display at the Heritage Museum, were used to create different body odors and enhance the authenticity of their transformations.

"Medicine", more not simple, ninjas are usually a doctor and drug experts, good use of various plants and herbs to cure injuries and diseases. Long time lurking in order to avoid mosquito bites, ninja carry a large number of insect repellent, in addition to incense, potent poisons, andrography, lust goat ho and other medicines used in different tasks, breathtaking.

"Qi" means that ninjas focus on cultivating their bodies so that they can concentrate, be decisive and courageous, and remain unchanged in real battles, which is strikingly similar to the cultivation methods of the Wudang School of the Song and Ming dynasties in China.

"Body" means that the ninja focuses on the exercise of muscles and joints, along with meditation, breathing, massage, acupuncture, and other recovery methods to train themselves to adapt to a variety of martial arts techniques.

In addition to the "Five Ways of the Ninja" mentioned above, ninjas were also astronomers and chemists, able to look at the stars to predict the weather, and to make gunpowder and firearms. For example, the history of the famous ninja "Sarutobi Sasuke" to make the unique weapon is a range of 50 meters in the sudden fire gun, than at that time to firearms known as the Ming Dynasty army in the best bird cannon gun range is twice as high. It is a pity that Sarutobi Nikki was killed in a trap by mistake, and his mysterious weapon has never been found, which was cited as a pity by the history of Japanese arms.

The ninja's martial arts and the Japanese samurai's martial arts are fundamentally different, ninjas due to the implementation of the mission of the special, usually do not use a large sword or spear, but the use of easy to carry short weapons and concealed weapons. Legend has it that during the Ming dynasty in the Central Plains martial arts called "octagonal diamond" hidden weapons, pure steel to build, sharp as a knife, thin as paper, the size of only two inches, scattered as the sky flower rain, and fed with poison, most likely from the hands of the Japanese ninja. And ninja hand-to-hand combat is also a great, ten fingers like steel like iron, through the chest and abdomen, tearing the neck crack head, instantly make people to death, although less than the depth of the Chinese martial arts, but the practicality of the strong, fully in line with the fighting "one strike to win" the basis of the idea.

The ninja's residence is also mysterious and secretive, with hidden mechanisms everywhere, in order to guard against the threat of ninjas under other ruling powers. From the outside, it seems to be just an ordinary house, but the floor next to the seat is usually installed with a spindle, when an enemy breaks in, tap the wooden board, the back immediately flipped, revealing weapons, sword fight. The roof boards are also movable, and pulling them down is a folding staircase, making it easy to hide or escape. The traditional Japanese room door is a sliding door, the same as easy to be blocked, and in and out of the sound is large, so the ninja room door is a turnstile, you can not show, unexpected counter-attacks on the other side. Wall panels are everywhere in the dark door, or used to escape, or hidden weapons, there is a Koga flow ninja room wall competing with seventeen dark holes, more than thirty kinds of different weapons, is simply an invisible weapons display cabinet.

There are countless magical legends about ninjas, and interested readers can look up the records of ninjas in Japan's Warring States period, or take a stroll through the Ueno Ninja Village. Today, the true meaning of the ninja no longer exists, but hard work and diligence, tenacity and toughness of the characteristics of the Japanese people as the best part of the character of the inheritance. Perhaps, the Japanese can create a post-war economic miracle, relying on this ninja spirit.

Japanese ninjutsu

The origin of ninjutsu

The theoretical basis of ninjutsu was Sun Tzu's Art of War, which came to Japan from China, and then it was combined with the practice of Taoism and the skill of ambushing in the mountains

The art of ninjutsu was developed. During the Heian period, the art of ambushing in the mountains was developed by the samurai due to the rise of the samurai class. In the Genpei period, Minamoto no Yoshitsune, who had learned to ambush in the mountains, succeeded in using the technique of the mountain ambush and completed the theory of the attacking surface method of warfare

. During the Northern and Southern Dynasties, Masanari Namiki developed the defensive side of the art of war, and it was at this time that ninjutsu and martial arts were separated into different systems

●Schools of Ninjutsu

Ninjutsu began to progress greatly during the Warring States period, when there was a great need for ninjutsu, martial arts, and the art of war.

But unlike the art of war and martial arts, ninjutsu had its own uniqueness. There are several regions where Ninjutsu is well developed, and the schools of Ninjutsu are also

named by the names of the following places:

Musashi, Kofu, and Echigo

Shinano, Iga, and the other four states

Koga, Kii, and the three other three states

With the latter three states being the most advanced in Japan, the Ninjutsu of these three states is the most advanced in Japan.

●Ninjutsu textbook "Manekawa Jikai"

Originally, before the Yamato invasion, Iga and Koga were called IGA, but later, during the Muromachi and Sengoku eras, the names of the places were separated, and so were the schools of ninjutsu.

But even though the schools were separated, the ninja practiced the same classic book, which we call "Manekawa Jikai".

This book has all the theoretical foundations and skills to teach the ninja how to perform ninjutsu. (Note: This is the same ninja textbook mentioned in "Sengoku Meijin~Zenkoukou" and "

Ninja Gantaro").

●Why did Iga and Koga develop their ninjutsu so much?

Iga and Koga are both close to Nagoya and Kyoto, and are located in a small, enclosed basin surrounded by mountains,

a world of their own.

But the location is strategically very important. Because of its proximity to Kinki, the center of Japan,

Kyoto's cultural influence is very strong. There were many shrines, temples and manor houses. Later, when the manor system collapsed, the landed gentry rose up one by one. During the Warring States period, there were actually 60 tycoons on such a small piece of land, but because the land was so small,

everyone wanted to take over each other's land, so each family would raise about 30-40 soldiers to deal with the "enemy" (this is very similar to

Taiwan's era of reclaiming land, when there were armed battles between villages of the southern Minnan people over land, and also somewhat similar to the Minjiao fighting each other). This is very similar to the fights over land between villages of the Minnan people in Taiwan during the era of land reclamation.) The competition here is more fierce than anyone can imagine. The tycoons allied with each other, scouted each other for enemy information, and slaughtered each other, and once a tycoon was defeated, it would be hard for him to

get back up again, so it's no wonder that such a mountainous place with fierce battles became a base for the development of ninjutsu. As time went on, a balance developed between the various local communities, and the art of jutsu began to dominate the country.

●The origin of the theory of Ninjutsu

Ninjutsu came from the peasantry, not from the noble samurai.

The mountain ambush techniques of ninjutsu came from the mountain warfare experience of those who lived in Yamato, Yoshino, Kurama, Nenrai, and Iga.

Kyoto is the birthplace of yin-yang-do, the magic used in ninjutsu, because the main mountain of the Buddhist Tantric sect of Hikono is not far away.

The martial arts side of ninjutsu is derived from the Ryusei-ryu Sword School and the Hoshoin-ryu Gunnery.

●Chinese and Korean immigrants and ninjas

The Yamato court welcomed people with skills from outside Japan to settle in Japan. Therefore, a large number of people from China and Korea came to Japan.

For example, many of the masters who made pottery, armor, and clothing came to Japan from China and Korea. These people usually settled in Kyoto, and then some moved to nearby Iga or Koga to work.

In addition, there are a lot of foreigners and naturalized people (foreigners who became Japanese and changed their surnames to Japanese).

For example, in the early days of the Tokugawa Shogunate, when Hattori Hanzo was working with Ieyasu, many people from Iga and Koga followed Hattori and moved to Edo

to live there. The town of Matubo is a transformation of the towns of Iga and Koga. There is still the name of Hanzomon (the old house where Hattori Hanzo lived). It is said that Hanzo Hattori was a convert. His family was originally Chinese, surnamed Qin, but later, because they settled in Japan, they changed their Japanese surname to Hattori in order to merge with the local

and the Hattori family was born from there.

●Influence of foreign craftsmen

In addition, technology introduced by foreigners, such as gunpowder, took root in this area, and it was a place where gunpowder was manufactured from the earliest times in Japan.

Other craftsmen also took root here, such as craftsmen and doll makers. ...... All kinds of craftsmen came here ....

... As a result, there were many such people in the Iga and Koga regions, and the ninjas were able to use the skills of many of these craftsmen in their espionage work in the future. However, in the society of that time, the status of these people was not high (in their homeland, China and Korea, the status of these people was not high either, and merchants were at the end of the four classes of the people, namely the Shishu, the peasantry, the industrialists, and the businessmen; of course, there were also classes of Shishu, peasantry, industrialists, and the businessmen, but Shishu

meant Shidafu, which was a samurai warrior).

●Favorite Ninja General - Takeda Shingen

Because Shingen hated having his country's secrets known to others, he loved to train ninjas. He loved to use the ninjas he had trained (he called them "Chaobo" and "Sanshin", which was also the Takeda family's name for ninjas. The origin of "Kabuto" is that they came from the Koshi, Noboru, and Echigo regions, or a group of robbers organized them and taught them mountain warfare and other

fighting techniques, and so they became ninja. In addition, the "three," a generic term for "Mamiya," "Mihata," and "Megumi,"

were specialists in scouting and espionage. Shingen sent Tomitago Saemon to command the "Three" ninja.

●Hideshi Hashiba and Kohroku Hashiba

It is well known that Hideyoshi Hashiba, when he had nowhere else to go, turned to Kohroku Hashiba and ate at his house for nothing.

Hesuga Kohroku was an active "night bandit" (a bandit, or at best a samurai, who did not find an army to employ their

masters, or at worst a mountain king who came out at night to steal money) in the Mino area. Anyway, people who work for bandit groups aren't usually poor,

so it's possible to be hospitable enough to get some people who don't have any food to defect to him and eat at his house. Later on, these people, for helping Hideyoshi?

These men became a government army after they helped Hideyoshi to take over the castle of Mugu

and finally got rid of their bad reputation as bandits. However, since Nobunaga hated the bad army with poor military discipline, Beezusu

Ga Kohroku and his group of bandits never did any more killing or killing again, but the general skills that they had developed in the time of banditshad been a condition for becoming ninjas. They became ninjas in Hashiba Hideyoshi's army.

And they performed well in all the major battles.

●The history of the name ninja

The name ninja was first introduced in Japan during the Edo period, but the history of the ninja goes back much further

. It is said that the first person to send a "ninja" on a mission in Japan was Prince Tokushin. At that time, ninjas were called "shinobi. Depending on the time and place, there were various names, and the following are the current names of ninja in each period: Asuka Period (飛鳥時代

: "shinobin"); Nara Period (奈良時代: "scout"); Warring States Period (战国時代): there were many different names, and the most popular one was "chaiba", which was given by Shingen Takeda

. Edo period: "Ninja".

Although the name was formalized during the Edo period, it was during this period that Japan entered a longer period of peace under the Tokugawa family, and activities on the stage of history became less and less frequent. The loss of the stage of activity caused the

ninja to disappear from the stage of history. So much so that many jutsu were lost. The last record of ninja activity was in 163

7 during the Shimabara Rebellion, when the ninja fought as part of the Shogunate's deployment.

●Origin of Ninjutsu

Ninjutsu is also known as the art of concealment. The origin of ninjutsu and ninjutsu varies, with some people in China believing that ninjutsu originated in the Han

generation of China as a five-element art, which later spread to Japan. Like karate, judo, shaolin boxing and other Japanese martial arts, ninjutsu is a distinctive Japanese martial art that was gradually developed by the Chinese

ancient martial arts that came to Japan. The authoritative work on ninjutsu, "Manchuan Jikai", states that the idea of ninjutsu

has its roots in Luwang, the Grand Duke of Jiang at the time of the Yin and Zhou dynasties in China. It was he who first proposed the concept of ninjutsu, which was written in the heirloom masterpiece Liu Tao (六

韬). Later, Sun Wu, Zhang Liang and Han Xin refined the theory of Ninjutsu. In particular, Sun Wu's "The Art of War

" was highly respected by the ninja class. At this time, Ninjutsu also basically formed a prototype consisting of several parts, such as power and strategy - formation - yin and yang - techniques and so on

. As the art of ninjutsu spread to Japan, the ninja appeared and developed in Japan.

The Japanese believe that the theoretical basis of ninjutsu evolved from Sun Tzu's Art of War, which came to Japan from China, and was later combined with the practice of Taoism and the ambush techniques of the mountains, which are known as the Four Character Truths of Wind, Forest, Fire and Mountain. During the Heian Period (794-1192), the samurai warrior class developed the art of mountain ambush warfare. In the Genpei era, Minamoto no Yoshitsune succeeded in using the technique of mountain ambush and completed the theory of attacking surface warfare. During the Northern and Southern Dynasties, Nanoki Masanari developed the defensive side of the art of war

and it was at this point that Ninjutsu and martial arts were separated into separate systems and formalized.

The Chinese and Korean immigrants also had a great deal to do with the development of ninjutsu. Because Japan was very backward in ancient times, the Japanese government

welcomed immigrants from China, which was highly developed in science and technology, to settle in Japan, and Koreans, who had been influenced by Chinese civilization, were also welcomed, and the Japanese called these immigrants "naturalized people" (although they were welcomed, they were still discriminated against, and the immigrants could hardly enter the upper-class society, and they could not use their original languages and cultures, but had to change to Japanese names and use Japanese names). (Although welcomed, they were still discriminated against, as it was difficult for immigrants to enter the upper class, and they could not adopt the language and culture of their original place of residence, but had to change their names to Japanese and use Japanese). These ancient technological

immigrants brought a great deal of advanced science, technology, and cultural knowledge to Japan, such as the manufacture of pottery, armor, and clothing techniques, as well as the decidedly

qualitative Chinese martial arts that contributed to the development of ninjutsu in Japan. Because the ninja's origins were mostly from peasants at the bottom of the social ladder, rather than

samurai of noble birth, it was difficult for them to be accepted by the upper class. Therefore, as immigrants who were hardly accepted by the upper class, "naturalized people" also entered the ninja profession in large numbers.

"Naturalized people" were usually the most common form of ninjutsu. The naturalized people usually settled in Kyoto, and then a large number of them moved to nearby Iga or Koga, which

was also the main reason why ninjutsu developed so well in these two places. For example, the famous Hattori Hanzo Masamune was a Chinese man named Chin, and the Chin

family was a stronghold for the development of ninjutsu in the late third and early fourth centuries from the Chinese state of Kure, the traditional name for the Japanese kimono

. Iga's and Koga's greatest contribution to the ninja cause was the

systematization of the theoretical foundations and skills of ninjutsu and the compilation of a ninja's training manual, the Manchuan Jikai. Although the genre

●A Ninja's Path to Cultivation

Ninjutsu flourished during the Warring States period in Japan because of its extreme practicality. Ninjutsu is a complete system of espionage and intelligence techniques mastered by ancient Japanese ninjas, including tracking, reconnaissance, espionage, bodyguarding, assassination, and many other aspects. Ninja

superhuman skills, good at using swords, hooks and other weapons and shuriken and other concealed weapons; they can fly over the eaves and walk on the wall, running in the sand without making

a little noise; hold their breath in the water for up to five minutes, such as special equipment can be stayed under the water for a day and a night; they are good at fighting on the surface of the water

and under the water, and even dive to the bottom of the ship, eavesdropping on the boat's conversation! ...... All of these superhuman skills were acquired through inhuman training

.

Spiritual training: Ninjutsu and other martial arts schools emphasize physical training, but it especially emphasizes spiritual training, and its

entire training system, based on an unimaginable spiritual training. Because most of the tasks performed by ninjas are high-risk missions from which there is no return, and accomplishing them alone in the enemy's lair involves overcoming many difficulties such as fear of death, loneliness, darkness, and even hunger, cold

, and injury, the possession of strong spiritual power is the real reason why ninjutsu is indestructible.

As a descendant of a ninja clan, one must accept the harsh reality of fate as soon as one is born - either become a ninja or

die. From a very young age, ninjas are taught to be absolutely loyal to their masters: they will not listen to anyone but their masters, not even the Emperor of Japan. Through this mental brainwashing from a young age, the ninja are created to be more fanatical and fearless than any religion

. But ninjas aren't zombie-like warriors like cultists, either; they have a

practical training method for powerful mental strength. It is this technique that is the secret of ninjutsu, and it is the practice of dōmi. East

The Secret and our country's Tibetan Tantra, India's miscellaneous Tantra, is the same, is a branch of Buddhism in the Tantric sect, and the East Tantra for the development of the human body's numinous power

has always had its own unique inheritance, and has always been known in the Tantric world for its remarkable speed, ninjas, through through the East Tantric secret method of practice,

hammers their own wills, the spirit becomes incomparably pure and tough, and the potential of the body will be developed to the fullest extent. The mind can be completely freed from confusion and fear, and the mind can be fully focused on the battle. In addition, Tantric Buddhism believes that the human body has many mysteries and potentials, and that through the tireless efforts of Tantric Buddhism, the practitioner can realize his full potential, allowing his body to communicate with the universe and reach the realm of heavenly and human harmony

, which is similar to the extreme physical arts pursued by ninjas. Tantric Buddhism regards Dainichi Nyorai as the Lord of all things, and strongly promotes the transmission, truth and secret

mantra.

Skill training: Children of the ninja clan, both male and female, are required to carry on the occupational traditions of their ancestors, and are generally trained from the age of five.

There are five types of training. There are five types of training: balance, agility, strength, durability, and special techniques. Balance training begins with walking on bamboo poles

and when one can walk on a rounded bamboo pole without slipping, the pole is gradually raised to a height of 30 to 40 feet, so that

the person is able to run and jump as if he were walking on a flat surface, and can then climb and climb up and down trees, rooftops, and walls as if he were flying. Sensitivity training is also

so jumping over ropes with razor blades stuck in them, and turning corners and hurrying through narrow paths full of sharp blades and gun points. Durability and strength training

The most grueling training is hanging from a tree with your hands supporting your whole body, with concealed weapons underneath, so that you can't let go and jump, and using fear to stimulate your body's

potential for long-lasting support. Long-distance running is even more basic ninja skills, requiring continuous running on the road for 50 kilometers without stopping to rest,

100 miles a day is commonplace. The training in special techniques is even more astonishing. In addition to those mentioned above, there is also hand-to-hand combat, throwing

perseverance, endurance, and fighting strength beyond the norm. A ninja who has survived training in ninjutsu is an absolutely reliable, full

power fighting machine.

●Ninja and Samurai

During the Warring States period, the ninja and samurai were both in the service of the daimyo, but the ninja and the samurai were on opposite sides of the spectrum, with the ninja being a slave and the samurai being a retainer. Because the ninja's work was mostly secret, involving power struggles in the upper echelons, and

dangerous, they often came to a sad end. The danger came first from their employers. After achieving their goals by any means necessary, these sinister and venomous figures at the top of society, fearing that the inner workings of the matter will be leaked, will often kill the ninja carrying out the mission to silence them.

Though the ninja were superhuman, they often miscalculated in their missions. One ninja braved the summer heat to

sneak into a vassal's house to assassinate him. He dug a hole in the earth with his hands so as not to make any noise, and it took him more than ten days to get under the tatami mats in the room

. Just as he was about to succeed, the stench of his sweat attracted flies and mosquitoes, and the buzzing

of the insects aroused the suspicion of one of the guards, who drew his sword downward and stabbed through the floor, killing the ninja who was hiding below.

The ninja's worst enemy was the samurai. The samurai hated the ninja because they were in the open and the ninja were in the shadows.

Once a ninja was captured by a samurai, he would be killed by the most brutal forms of torture. Skinning is one kind of torture, the skin was peeled off piece by piece

down, extremely painful, but can not die immediately. That's why the ninja would never let the samurai take them alive. Here is the story of one of the most legendary ninja of all time. This ninja was named Sarutobi, because he had the ability to climb and leap like a monkey in the trees, coming and going without a trace; at the same time, he was also very good at hand-to-hand combat, so people could not catch him. Once he was sent to spy on a general who lived in a city

fortress, and overheard a secret conversation between the general and a minister. But when he left the castle he was discovered by the guards, and he immediately leaped up

the ramparts, skillfully avoiding his pursuers, but as he jumped down into the garden he stepped on a concealed steel trap for a bear, which caught his leg in a tight

hold. When the general's guards came around, Sarutobi saw this and cut off the pinned leg with a single slash, escaping on one foot for a long

distance. But in the end, he lost too much blood and had trouble supporting himself. Seeing the guards getting closer and closer, and knowing that he had no hope of escaping, Sarutobi simply stood

still, shouted insults at the pursuing guards, disfigured his own face with his sword to make it unrecognizable, and then swung his sword to slice off his own

neck. Thus sadly ended the life of a renowned ninja.

Those who survived were often lonely. Oni Hanzo, who served Tokugawa Ieyasu for many years, was a ninja who was good at both the black

and white paths. He was trusted by Tokugawa Ieyasu, saved his name countless times, and participated in the wars of the Three Rivers Legion many times, so his life could be considered as a typical ninja of the most brilliant, and his salary at the time of his death was only 8,000 koku, which is only a fraction of the salary of the same meritorious samurai. Fractions of the treatment of generals ......

Why were the ninjutsu of Iga and Koga so advanced? Iga and Koga are close to Nagoya and are located in a small, enclosed basin surrounded by heavy

mountains, making them small worlds in their own right. However, they are strategically important. Because of its proximity to

Japan's central Kinki region, it has been y influenced by the culture of Kyoto. There were many shrines, temples and manor houses. When the manor system collapsed, the landed gentry rose up one by one. In the Warring States period, there were 60 tycoons in such a small area, but

because the land was so small, everyone wanted to take over each other's land, so each family would have about 30-40 soldiers to fight against the "enemy", and ninjas became an important force.

Favorite Ninja General - Takeda ShingenTakeeda Shingen loved to train ninjas because he hated the idea of his country's secrets being known to others. He loved to use the ninjas he had trained (he called them "Kabuto" and "Sansho", which was also the Takeda family's name for ninjas

). The origin of the word "Habanero" is that the ninja came from the Koshi, Noboribetsu, and Echigo regions as vagabonds, or a group of robbers organized them and taught them mountain warfare and other fighting techniques, and so they became ninja. In addition, the "Sanjin" is a generic term for "Mamiya," "Mihata," and "Megumi

Fu," who are experts in scouting and espionage. Shingen sent Tomitago Saemon to take charge of the "Three" ninjas.

●List of famous ninja

The Momiji Santao, also known as Momiji Tamba, was a ninja who lived in the Iga Ueno region. He was a tycoon based in Ueno, Iga, and one of the three great ninja of Iga

. He repelled Oda Nobuo's Iga Heiding Army at Onigoma-horide. He was a legendary ninja who fought against the Oda family all his life.

Ishikawa Goemon, an Iga ninja. As a subordinate of Momiji Mitao, he once infiltrated Osaka Castle to try to assassinate Toyotomi Hideyoshi.

Unfortunately, he was discovered when he accidentally touched the treasure "Chidori's incense burner", and was later executed by Toyotomi Hideyoshi.

Kotaro Kazamora was the leader of the Sagittarius Chaos. Served the Hojo family for five generations. He collected wartime information for the Hojo family and carried out

subversive activities against the enemy. Legend has it that Kotaro Kazamora, who stood 7 feet 2 inches tall, is said to have organized a group of thieves in Edo Castle after the fall of the Hojo family

. He led the "Kaze Demon Party," a group of ninjas who were active in the yakuza, and many legends have been passed down in Japanese folklore.

Sadao Suzuki was the leader of the Koga clan. The Koga clan was a group of mercenaries who used iron cannons (muskets) as their main weapon. Since iron cannons were precious at that time, the battle power of the Koga clan was not to be ignored. He collaborated with Honganji Temple to fight against Oda Nobunaga. He was later killed in a battle with Toyotomi

Hideyoshi!

Hattori hanzou masanari (1542-1596). The Hattori ancestors were originally descended from the Chin clan, one of the great clans of ancient Japan (mid-6th century), who were immigrants who had crossed the sea from the Chinese state of Wu. The Chin clan not only taught the Japanese the art of weaving, but they also opened their eyes to the Japanese by organizing "shinraku" performances all over Japan. The so-called "shinraku" was a popular performing art developed in China between the end of the 3rd century and the beginning of the 4th century. It consisted of songs, dances, acrobatics, power tricks, magic, puppet shows, ventriloquism, and training of small animals such as dogs, monkeys, and birds to perform for the entertainment of the general public. It is said to be a new type of skill that combines Tibetan and Chinese performing arts. At the time, the Chin group mainly toured cities and temples in southern China, but later the organization expanded and spread throughout China. Two or three of these groups crossed the ocean to Japan in search of new horizons. The traditional name for the Japanese kimono is "Kure", which is derived from the country of Kure, where the Chins came from.

The Hattori clan was one of the subgroups of the Chin clan. When did they move to Iga? It is not clear. How did the Hattori clan develop the skill of "Shinkaku" into the art of war and ninjutsu? There is no detailed historical data to trace the origin of the Hattori clan. In any case, the Hattori clan left their home in the early 15th century and became vassals of the Matsudaira family under the daimyo Matsudaira Kiyoyasu (Ieyasu Tokugawa's grandfather). As a vassal of the Tokugawa, Hattori Hanzo led the Iga ninjas in many battles. He was called "Oni Hanzo" in fear of the people. From then on, the leader of the Tokugawa family's ninja forces was honored to inherit the title of 'Hanzo'. However, both of Masanari's sons were tragic figures: his eldest son, Hattori Masanori, was relegated to civilian status by Tokugawa Ieyasu after his selfishness and stupidity provoked a mass rebellion among the ninja under his command (an extremely rare occurrence). Later, in an attempt to revitalize the family, Masato participated in the "Summer Battle of Osaka" in 1615, when Tokugawa Ieyasu attacked Toyotomi Hideyori, and was killed in battle. His second son, Hattori Masashige, was also implicated in the suspected rebellion of his wife's mother's family and was punished by exile, and finally died in poverty in a foreign land.

Shimotsuki Noki Saru-Kozaru (小猿), birth and death dates unknown

Shimotsuki Noki Saru (下柘植ノ木猿-小猿), one of the eleven daimyō of Iga, was one of the eleven daimyōs of Iga. He is known for his special skill of driving apes and monkeys, and for his invisibility in trees. Kizaru's real name is Sasuke Kamitsuki, so some people say that Sarutobi Sasuke, one of the Ten Warriors of Sanada, is actually referring to him.

Sasuke Sarutobi (Koukichi)

One of the Ten Warriors of Sanada. He was given the name "Sasuke" for his assistance to Sanada Saemon Sa Yukimura. Sarutobi Sasuke's name appears in the "Osaka Natsu no Jinyu Allocation Formation Chart" from the late Edo period (1825). According to the Tachikawa Bunko, Sarutobi Sasuke was the son of Satao Washio (Washizuka), a samurai from the village of Torii-tōge in Shinshu, who practiced under Tōzawa Shiranunsai, the master of Koga-ryū ninjutsu, and became a retainer of the Yukimura family.

Ning was Toyotomi Hideyoshi's original main wife, over 40 years older than Maeda Keiji, and not related by blood. I don't know now, I'm asking a question and waiting for an answer!
