Japanese Sign Language (日本手話, Nihon Shuwa), also known as JSL or NS, is the main sign language in Japan.

In 1878, the first school for the deaf was established in Kyoto.
In 1900, the Tokyo School for the Deaf (東京都立ろう学校, Tokyo ro-a gakko) was founded.
In 1948, Deaf children were required to attend school.
In the late-20th century, Japanese sign language began to be recognized.
The Japanese Federation of the Deaf is for those Japanese whose primary language is JSL.
JSL has a friend in the Imperial family. Kiko, Princess Akishino has studied JSL and is a trained sign language interpreter. She also signs in informal Deaf gatherings.
In 2006, the Japanese government amended the "Supporting Independence of People with Disabilities Act." The new language in the law encourages local governments to increase the number and use of JSL interpreters.
As in other sign languages, JSL (usually called simply 手話 shuwa, "hand talk") consists of words, or signs, and the grammar with which they are put together.
