Casinos in Japan: 2026 guide
None of the operators listed below holds a licence of this country — all of them work under foreign licences.
Regulation
Japan has traditionally banned most forms of gambling, including online casinos. Only certain formats are legal — state lotteries and 'public sports': horse racing, keirin cycle racing, boat and motorcycle racing. Pachinko is hugely popular and is formally not considered gambling because of its prize-exchange scheme. For casinos the country created a legal framework for integrated resorts (IR): the first complex is being built in Osaka and is due to open in the second half of the 2020s, with strict restrictions for local residents, including an entry fee and visit limits. Online casinos remain illegal, and taking part in them is risky. The currency is the Japanese yen; cards and bank transfers are used. Players should note the ban on online casinos and expect the legal land-based segment in the IR format.
