Very useful information about JSL (Japanese Sign Language). Has the ability to teach the basic instructions of sign language for Japanese. Along from lettering it has simple direction giving, questions, personality and descriptions. All basic but at enough of a level to where one would be able to help hearing impaired. Interesting and useful site. Would recommend basic understanding of Japanese vocabulary and writing system to fully incorporate these.
