If an online casino in Japan offers No Deposit cash or Free Spins, you will find that out on their Promotions page. Betting platforms always brag about their No Deposit offers, so be sure you won’t miss it if it is there. And if it is there, you will be able to get it as a reward for activity, usually – for signing up to the site. Please keep in mind that whatever you win by using Free Spins (or cash, or chips) is subject to wagering requirements.
