A genuine, legal keirin (bicycle racing) pari-mutuel betting portal, operated by K Dreams Corporation, a wholly owned Rakuten subsidiary since 2014
Not available lawfully hereIs Rakuten Kdreams legal in Japan?
No. Real-money gambling is banned in Japan. Under the Penal Code gambling offences and the revised Basic Law on Measures against Addiction, in force since the revised law took effect in September 2025, Rakuten Kdreams cannot lawfully offer you a welcome bonus here, and you cannot lawfully claim one.
Only public pari-mutuel sports and lotteries are legal in Japan; offshore online casinos are not. Online casino-related arrests hit a record 196 in 2025, up more than 38% on 2024. The revised law also criminalises intermediary 'reach' sites and social media promotion that funnel players to offshore casinos, and the first arrests over an affiliate site followed in September 2025. source
Any Rakuten Kdreams bonus you see advertised for Japan is offered from an offshore site operating against local law. Your payments can be blocked, your account can vanish with a mirror domain, and no Japan regulator can help you recover funds. We therefore show no offer and no sign-up link on this page.

Our verdict
Rakuten Kdreams is a genuine, legal keirin (bicycle racing) pari-mutuel betting portal - we located the correct official domain (keirin.kdreams.jp) after the prior session's domain-resolution failure, and independently confirmed via a second source (Japanese Wikipedia) that it is operated by K Dreams Corporation, established 29 June 2009 and fully acquired by Rakuten in September 2014 as a wholly owned subsidiary. It falls under JKA (Japan Keirin Association) jurisdiction via the Multi-Win Betting Electronic Settlement System Management Council - the same legal, government-linked public pari-mutuel system as the related Rakuten Keiba brand, and distinct from the offshore online casinos Japan bans. No traditional welcome bonus applies to this pari-mutuel format; players instead earn Rakuten Points on their bets.
