We are pleased to announce the launch of the English version of “Signs I/O”, a web service operated by General Incorporated Association Shikaku (headed by Kohei Ito) that allows users to learn Japanese Sign Language (JSL) anytime, anywhere online.

The newly released English version is based on learning materials that have been provided by Signs I/O. We hope you enjoy it!

About Signs I/O

Signs I/O was launched in 2019 as a web service where you can learn JSL anytime, anywhere online. With Signs I/O, you can learn JSL in a fun and game-like way. All instructors are Deaf, native signers of JSL.

From Us

We really appreciate the contributions from many people in creating the English version of Signs I/O. We are elated that we can offer opportunities for people all over the world to learn JSL.

On Signs I/O, we provide materials so that people can learn about not only JSL and Deaf culture, but also Japanese culture. We hope that more people will enjoy learning with Signs I/O!
