Expert Opinion
Christian Howells
Assistant Editor / Bingo & Casino Expert

Online casinos in Japan have a habit of offering free spins bonuses as part of a welcome bonus or ongoing promotions. You should not underestimate the importance of such deals. Especially since some platforms deliver up to 250 free spins, creating more opportunities to play for fun and potentially win real money. The wagering requirements will not be low, most have a 45 x playthrough, but the sizable bundles of free spins make these bonuses an appealing prospect.

🏆 How to Choose the Best Casino Site in Japan

There are countless online casinos in Japan, but not all should be trusted. That’s why we have developed a scheme of criteria that can help you find the best casinos. Here are the parameters to pay close attention to:

1

License & Security

How to Choose the Best Casino Site in JapanWhen playing at online casinos, you must be sure that your funds are protected and that the games offer fair outcomes. To ensure safety, join an operator licensed by a reputable regulatory agency. Most online casinos in Japan hold a Curacao license, but casino sites validated by MGA are also good destinations. In addition, checking the availability of SSL encryption protocols can guarantee your information’s security.

2

Bonuses and Promotions

Look for a packed promo page with deposit matches, free spins, no-deposit casino offers, and cashback bonuses. Start by searching for a large welcome bonus, and make sure you can claim ongoing promotions. Always consider the stipulations you need to meet when using a bonus. Our recommendation is to pick bonuses with low rollovers and qualifying deposits.

3

Wide Variety of Games

A casino without a variety of games is not a good casino. You need to satisfy your gaming tastes and have an opportunity to explore new gaming horizons. Games are the driving force of casinos, so aiming for game libraries with over a thousand of slots, and live dealer games, instants, crash, and video poker games from a long list of software providers is a good idea. The games should offer diverse themes, high RTPs, and multiple bonus features.

4

Deposit and Withdrawal Methods

A good casino must accept multiple payment options. In most casinos, you can make transactions through e-wallets, wire transfers, credit or debit cards, and some cryptocurrencies. Yet, not every brand offers the same transaction speeds, security features, and fees. Focus on access to renowned payment providers. Additionally, look at the operator’s payment policies, try to find the withdrawal processing speeds, which must be quick, and if any fees will diminish your winnings.

5

Mobile Compatibility

It’s crucial to choose casinos that are optimized for smaller screens. The best method for mobile gaming are casino apps for iOS and Android smartphones. Intuitive navigation and fast load seeds are imperative. The games must run smoothly without any major issues on the casino apps or in-browser experience.

5

Customer Support Service

The FAQs provided are not always sufficient, considering how many features a single casino can have. For this reason, 24/7 customer support for additional questions and problems is essential. Good customer support offers live chat and a dedicated email. The response times must be fast, and the agents should be able to answer questions relating to the operators’ policies about bonuses, payments, and games.
