What are the national musical instruments of Japan?

Sakuhachi, koto, Shamisen, and Biwa are the most important traditional musical instruments in Japan. Sakuhachi (shakuhachi) is a vertical instrument made of bamboo tubes with five holes, and was widely played by a group of monks during the Tokugawa period. The playing of shakuhachi was combined with the spirit of Zen Buddhism in order to achieve enlightenment, which is known as blowing Zen. This is called Zen blowing. Therefore, when playing the instrument, the sound is released through the instrument either by inhaling or blowing, and it is interpreted with the utmost spirit. The Koto is a large 13-stringed koto played in a kneeling position with the first three fingers of the right hand, and the body of the koto lies flat in front of the player. The Shamisen is a three-stringed instrument derived from the banjo, played with large tortoise shell-like shrapnel, and is associated with kabuti, a traditional Japanese kabuki, and is based on a portion of the Nagauta, a traditional ballad from the Shodo period, and is therefore played in a short time of about two and a half minutes. Ogi No Mato (The Folding Fan as a Target) is a solo piece by Biwa, a Japanese lute with five strings plucked with wooden plectrums, and is ten minutes and thirty-nine seconds long. It is very musical and distinctive, and the origin of the piece is closely related to a fan dance related to a legend.
