The first beginnings of the association began with a casual get-together organised in 1975 by Sharon Bode, then Chief Instructor at the Kyoto YMCA. A subsequent meeting was held at the National L.L. School in Osaka in spring 1976, where it was agreed to call the "organization" KALT and the group grew to around 60 members. The group's first event was a KALT-sponsored weekend conference in August 1976 at Kyoto YMCA attended by about 120 people. KALT as a broader organisation came into existence when the Tokai Chapter was formed in 1977, followed in the late 1970s by Chugoku, Takamatsu, and Nishi-Nippon. In 1977 KALT became JALT, and in September that year it became the Official Japan Affiliate of TESOL, and by the end of 1978, membership was around 800, alongside 30 commercial members. JALT was granted NPO status in 1999.
Chapters
JALT now has Chapters throughout Japan, and each member of JALT may belong to one chapter. Chapters take their names from the geographical area that they serve, although Nankyu is a created name. Chapters sponsor activities for language teachers in their area, and most chapter events are in English, though some are in Japanese.
JALT now has many Special Interest Groups consisting of members who share a professional interest. Members also have the option of joining one or more SIGs. SIGs provide publications, mailing lists, and are involved with conferences.
The full name of JALT's annual conference is Annual International Conference on Language Teaching and Learning & Educational Materials Exhibition. Conferences consist of plenary sessions, featured speaker sessions, and concurrent workshops and presentations. There are about 600 of these, and about 1,600 attendees, and there is a balance between practical presentations and theoretical. The Educational Materials Exhibition consists of displays of language learning textbooks, reference books and other language education materials.
Publications
JALT's first publication,The Newsletter, began in October 1975, and gradually increased in both size and quality. Its successor, The Language Teacher, was first published in April 1984. Originally released monthly, in 2009, a decision was made to begin publishing bimonthly in order to concentrate on offering more content online. It is a refereed publication, meaning that articles are subject to peer review, and is distributed in both paper and electronic form. The first annual conference proceedings publication was called TEFL Japan '77: Collected Papers whereas the most recent was the 2017 release of the JALT Postconference Publication - JALT2016. The JALT Journal is JALT's applied research journal which was first published in November 1979. It is still published semiannually, in May and November, with an emphasis on linking theory to practice.
