Online casinos and Japan: what the law says
Online casinos are not legal in Japan. 4 of the 46 operators we track name Japan on their own restricted lists; the rest simply do not mention it. Neither fact makes playing lawful where you are, so this page sets out the law rather than listing places to play. What Japan's gambling law says →
We do not list operators for Japan. Some of the casinos we track would accept a sign-up from here, because their terms do not name Japan — but online casinos are not legal in Japan, and putting a list of them in front of you with sign-up links would be promoting something the law here prohibits. The law is on the law page, enforced by the National Police Agency (enforcement).
Based on each casino's own restricted-countries list, not legal advice. Gambling law in Japan applies to you as a player; check it before you sign up.
