Every material claim must be traceable to operator documents, regulator records, or a named reputable source. Industry hearsay and untraceable "common knowledge" are not treated as facts.
All content is published under the collective byline of the Japan Bonus Editorial Team. No fictional personas, no fabricated credentials — that is stated plainly as policy. There are no invented experts on this site.
The principle is "commercially funded, editorially controlled." Affiliate commissions fund this site, and partner placements exist — they are labeled as such (the "Partner" chip on casino cards).
What is never traded: factual content and scores. Terms, licences and payout rules are reported as the documents state them, regardless of the commercial relationship. See the affiliate disclosure for details.
Our content is intended for readers aged 18 and over. We never suggest gambling is a way to make money or that winning can be guaranteed. Relevant pages link to responsible gambling resources and support organisations.
How to report errors, and how we fix them, is set out in our corrections policy. Material corrections carry a dated note.
