What was the level of Japanese combat effectiveness in the world during the Toyotomi Hideyoshi period?

In fact, to tell the truth, Toyotomi Hideyoshi's army was really strong at that time in terms of combat effectiveness. After all, the Japanese army at that time basically experienced the baptism of the Warring States period. Especially their musket technology was leading in the world at that time. At the beginning of the invasion of Korea, it was unstoppable and basically occupied the Korean mainland in a short time. As for why it finally failed, it is actually a bit like War of Resistance against Japanese Aggression's;

1, Japan is far from the local war and it is inconvenient to transport grain. Moreover, at that time, Japan had just finished the chaotic situation during the Warring States period, and production had yet to be resumed. It is really difficult to support 200,000 troops to fight for a long time.

2. The Ming army didn't go through a big war for hundreds of years, and it was at a disadvantage at first, and then its advantage was revealed. Japan, a small country, can't afford a long-term protracted war. The excellent command of individual generals in the Ming Dynasty made up for the lack of experience.

3. In the later period, Japan's maritime transport line was cut off by the allied forces of China and North Korea, which was unsustainable and accelerated the pace of failure.

4. In fact, although Toyotomi Hideyoshi unified Japan, in fact, his unification is somewhat similar to Chiang Kai-shek's unification of China. He was only the strongest in Japan at that time. In fact, there are many local people who are dissatisfied with him, only because of the disparity in strength. Tokugawa Ieyasu is a good example. At that time, the Japanese army that invaded Korea was basically transferred from West Japan, which was Toyotomi Hideyoshi's base camp. East Japan, headed by Tokugawa Ieyasu, basically didn't send people, only symbolically sent some troops. It can be seen that the internal contradictions in Japan were surging at that time. In fact, this factor indirectly led to the failure of the western army in the Guanyuan War after Toyotomi Hideyoshi's death, because the strength of the western army was seriously damaged in the process of invading Korea, while the eastern army was basically waiting for death.
