The Japanese guitar is a type of stringed instrument that has been used in Japan for centuries. The two most common types of Japanese guitars are the samisen and the ZITHER. The samisen is a three-stringed instrument with a long neck and a body made of wood, bamboo, or plastic. It is usually played with a plectrum called a bachi. The ZITHER is a six-stringed instrument with a flat soundboard and a hollow body. It is typically played with the fingers or a pick. Both instruments are popular in traditional Japanese music and have been used in various forms of entertainment.
