Online Betting Sites in Japan

This list covers bookmakers that serving readers in Japan. It is a reference table, not a search result: the ordering is fixed by measured traffic, so two visits to the page show the same ranking unless the underlying figures have been updated.

Daily visits are third-party estimates summed across the domains of an operator. Global rank places that figure against the whole directory, and the change compares it with the previous recorded ranking. A dash means the source publishes no value for that bookmaker in this group.

Requirements for including a bookmaker in this list

  • Sports betting is a substantial part of the bookmaker site, not an add-on to a casino product.
  • The source records measurable visitor traffic for the bookmaker in this group.
  • The bookmaker has a published review, so every row leads to a page with ranking and licence detail.
