Japanese ASL Signers Society (JASS) is a non-profit organization dedicated in introducing American Sign Language and Deaf Culture.  JASS was officially approved and certified by Tokyo Department of Justice on April 15, 2002 and thus changed our status as a volunteer organization to a non-profit organization.

It is an honor for us to announce the formation of JASS as a non-profit organization and we promise to keep our aim by contributing to the public interest through the cultural and language entrenchment.  We truly appreciate your interest.
We are also always on the look out for a Deaf ASL instructor.  If you are interested in becoming one of our instructors then please do not hesitate to contact us!  We will appreciate your interest and give you more information.

Activities and services currently available through JASS:
*ASL Classes
*International Sign (IS) Classes
*ASL retreats
*ASL/JSL tours in U.S.A.
*ASL Instructors/Interpreters
*The Nippon Foudation Overseas Scholarship Program for the Deaf
(higher education abroad)
*Newsletter (6 issues annually)

Why learn ASL?
ASL is used by the majority of the Deaf Americans in the U.S.A.  When Tokyo hosted the World Congress of Deaf in 1991, we realized that ASL was often used as the “contact” language by many people from international countries.  Gesture was also widely used but ASL is definitely in an unshakable position as the primary “contact” language.  JASS became more determined to offer ASL as a foreign sign language for members of the Deaf Community in Japan.  By giving the Deaf Community in Japan the chance to learn foreign sign language as well as cultural differences, one will appreciate his/her language and culture even more.  JASS has a policy that at least everyone should know basic Japanese Sign Language (JSL) before taking ASL courses.  JASS does recognize and value JSL as Deaf Japanese’s native language as well as other communication methods utilized by other members of the Deaf Community.
