What are the major publications for amateur astronomers in Japan? How do I subscribe?
The major publications for amateurs are Tenmon Guide, Skywatcher, and Gekkan Tenmon. In addition, the Oriental Astronomical Association has always encouraged membership of both professionals and amateurs. Its publication is titled The Heavens. All of these publications are, of course, written in Japanese. Of the three geared toward amateurs, Tenmon Guide is probably most like Sky and Telescope. The other two are more like Astronomy. The Heavens functions a bit more like a professional journal. If you are interested in subscribing to any of the three amateur publications, the best way to go about it is to send them e-mail. Most will be happy to answer your English inquiry and will let you know their policy on foreign subscriptions, prices, mailing costs, etc.
