itijo
Itijo is a traditional Japanese string instrument that belongs to the family of zithers. It is primarily used in the performance of min'yō, or Japanese folk songs, as well as in classical music traditions. The name "itijo" is derived from the Japanese words for "string" (ito) and "zither" (jo), though it is sometimes also referred to as the shamisen in certain regional contexts, though the shamisen is a distinct instrument with three strings and a longer neck.
The itijo typically features a pear-shaped body made from wood, such as hinoki (Japanese cypress) or sugi
Itijo is played with a plectrum, often made of tortoiseshell, horn, or plastic, held between the thumb
The itijo has historical roots in the nō theater tradition, where it was used to accompany nōgaku
