About The Site

Top Japan Casinos is a reference site about gambling as it relates to Japan, written in English for readers who want the mechanics rather than the marketing.

The site has existed since 2020 and has published in English throughout. What changed in 2026 is the shape of it: the material was rebuilt around three questions that readers actually arrive with — what does Japanese law say, what happens to the money, and how is the game itself built. Older articles were kept, because they are part of the record, and they now sit under the section that matches their subject.

What we publish and what we refuse to

Figures appear here only when an operator or a public body has published them first. Where a number does not exist in a verifiable form, the page says so rather than estimating. We do not run player testimonials, star ratings or invented expert scores, and we do not publish anything that reads as a recommendation to gamble. Pages about Japanese law state the criminal position plainly, including on pages that also carry commercial links.

How the site is funded

Some links to operators are commercial: if a reader opens an account through one, the site may be paid. Those links are marked on the page where they appear, and the ranking model that orders them is published on the how we rate page. Advertising does not buy editorial positions and operators are not shown the text before it goes up.
