In December 2016, the Japanese gouvernment has passed the legislation to allow casinos in Japan. That is also good news for chinese players. Chinese people are heavy tourist and they travel a lot to Japan because it is nearby. So, by these legislation, casinos in Japan can attrac Chinese tourists and hopefully they play in the casinos! But there is more: Japanese have a proven history of embracing wagering, has a large population and a lot of people with big money (wealthy middle-class) in their bank account. So there is to spend money and Japanese casinos will grow the coming years, even without the Chinese visitors.
At present, online sports betting and race betting is available, but other forms of gambling are prohibited. Since all online gambling is strictly prohibited in Japan, there are no domestic mobile casinos either. There are 180 Japanese online casinos, of which 'just' 26 online mobile casinos, that offer gameplay in English or Japanese language. They accept wagers in Japanese Yen (JPY) or US Dollars.
As you will see on our above composed list of japanses language casinos, you meet all kinds of software but most mobile casinos with a japanese interface are supported by Microgaming and a few with multi software, such as netent.
Japanese residents have to proove for themselves which japanese language casinos they can enter and play the online games.
