Tokyo International Amateur Radio Association



In-person meetings are cancelled until further notice.

The Tokyo International Amateur Radio Association (TIARA) holds monthly meetings in English usually in Jiyugaoka, Tokyo. Jiyugaoka is just a few minutes from Shibuya on the Tokyu Toyoko Line, or from Oimachi on the Tokyu Oimachi Line. Meetings are held on the third Friday of most months except August (Field Day & Ham Fair) and December (Christmas Party). The meetings are open not only to members, but other English-speaking hams and foreigners residing in or visiting Japan interested in amateur radio.

US Amateur Exams in Tokyo

The ARRL VEC Tokyo VE Team (which is not directly affiliated with TIARA, but which includes some members) conducts examinations for US amateur radio licenses at least twice a year in the Tokyo area. The next session will be announced when it is possible to again hold testing sessions. Information and pre-registration are available from ARRL VEC Tokyo. Start studying now! A US amateur license can be your gateway to getting a Japanese reciprocal license while you are here.

You can also check the ARRL US amateur exam registry for Japan to find other sessions.
