Online Gambling in Japan + Casinos List
Gambling is illegal in Japan. That's right, you can't play the lottery or go to a casino in this country. It makes sense though because gambling has been associated with a lot of crime and corruption when it comes to how it is handled in other countries around the world. The government does allow for betting on horse racing at designated tracks and there are also some forms of electronic gambling that are legal but nowhere near as popular as they are elsewhere like slot machines or poker games online.
When it comes to online casinos, Japanese residents can access plenty of them on the Internet. It is true that the government tries to block such sites, but there is always some workaround (VPNs and proxies).
