Japan Bonus is a free service providing information about online casinos with Japanese language support. To keep this service free for you, we partner with the casino operators we review and recommend through affiliate marketing.
When you click a link on Japan Bonus and register at a casino, we may receive a referral fee or commission from that operator. This commission is paid by the casino — not by you — and does not affect the price of any service you receive.
Affiliate compensation may be structured as a one-time payment per new player (CPA), a percentage of the operator's revenues (revenue share), or a hybrid of both.
Our editorial team, led by Aiko Shimizu, writes and maintains all reviews independently. We only partner with operators we consider reputable, but please be aware of the following:
All bonus offers and promotions on this site were verified at the time of publication. Casinos update their offers frequently. Always check the current terms directly with the operator before registering.
