Prediction markets in Japan

Of the 57 platforms we review, 27 are open to residents of Japan, 2 with restrictions and 7 exclude them. For 21 the published terms do not say either way.

The Penal Code prohibits gambling outside state-sanctioned categories, and the FSA supervises financial derivatives. Some platforms restrict Japan or limit it to closing positions.

Each line reports what the platform’s own terms say, with the source we read and when. It is not legal advice, and a platform can still refuse an individual account. Last checked 19 Oct 2026.
