The Japan Association of Translators (JAT) was founded in 1985 to facilitate the exchange of information and ideas among translators working between Japanese and English, and to establish and maintain professional standards in the industry. Membership is limited to individuals who are engaged in, or interested in, translation or interpretation. JAT was officially recognized as a non-profit organization (NPO) in Japan in April 2001. As of November 2018, JAT had approximately 700 members, about half of whom reside outside Japan. JAT offers members a wide array of opportunities and resources for professional development and networking.

IJET Conferences

The International Japanese-English Translation (IJET) Conference is JAT’s flagship professional development and networking event. First held in 1990, this annual two-day conference brings translators and interpreters together to network, share their experience and expertise, and further develop their professional skills. With the venue alternating between Japan and an English-speaking country each year, IJET has been held in locations throughout Japan and around the globe.

The PROfessional Japanese-English Conference on Translation (PROJECT) is a one-day conference that covers various aspects of translation and the translation business, and is designed to be of particular benefit to people just starting out in the profession. PROJECTs are held in major Japanese cities, usually in years when IJET is held overseas. Host cities have included Tokyo, Osaka, Nagoya, and Kyoto.

Regional Activities Committees

Regional activity committees hold regular seminars featuring presentations by JAT members and other specialists, covering topics such as professional translation tools and practices, how to establish a company, tax issues, industry standards, and the freelancer’s perspective, as well as networking and social events. Social gatherings are often held after these seminars at a nearby bar or restaurant to encourage casual networking.
