Winning too much\n\n So, if you're on a lucky streak, you might find that Bet365 restricts the size of the bets you can place to avoid significant losses for the company. Similarly, if Bet365 suspects you are a professional gambler, they may restrict your account for the same reason.
The answer is yes, but with some restrictions. Bet365 is legal in Japan, but the company does not have a license to operate in the country. This means that Japanese residents can access the Bet365 website and place bets, but they may not be able to use all of the features available to users in other countries.
