Usually, the online gambling sites in Japan provide game portfolios with hundreds of slots, including video, classic and progressive jackpot titles. Some games offer better payouts than others, but there are also games with higher betting limits or with more interesting symbols.

On the first site, you can even find games with over 97% RTP. This is the payback percentage that you will get from your wagers, and it is measured on average and per spin.

Of course, the higher RTP rate does not guarantee that the player would always win. You should not forget that the slot games are, before all, games of chance and the outcome of the game depends on how lucky you get in the first place. That being said, here are the slots sites with the highest payout in Japan.

This is one of the most amusing forms of gambling if you like to play online slots in Japan. The slot tournaments offer you the chance to compete with other players like you, for a shared prize pool. There are two basic ways to participate in such a game. It can be a freeroll tournament or a tournament with buy-ins. To enter in such a tournament, firstly, you should check if it is offered by your favourite casino operator, because not every operator has them. Here are the best free slot tournaments for Japanese players:

Actually, this is a recommendation for all sorts of promotions, including the ones found at the best poker sites in Japan.

Best Slot Bonus Offers for Japanese Players

Now, let’s talk about the best welcome bonuses available for new players at the Japanese casino slot sites. Each of our top 10 sites has a welcome bonus, however, we provide you with more details in the next table only about the best and most appealing ones. It comes down to the biggest welcome bonus packs with free spins and very nice wagering requirements. Here are the best slot sign up offers in Japan for 2022:

Slot Casino Welcome Bonus Min. Deposit Wagering Requirements Validity Safe Link
5000€ + 50 Free Spins 60€ 35x 30 Days Claim Bonus

Typically, the video slots offer a full (100%) contribution towards the wagering requirements of these casinos, but you should check out the terms of your favourite bonus very carefully before claiming it. Sometimes, the welcome bonuses include free spins that are valid for only one or two video slots from a specific software provider. Also, you should check out the bonus validity period and what is the minimum deposit required for a valid bonus request.

Well, you can play at online slot casinos in Japan for real money, and you would probably ask yourself ‘Is it legal?’. The answer is not that simple, as there are only a few legal options for gambling in Japan, such as sports betting and lotteries. All the other forms of gambling are illegal, and playing online slots falls into the so-called ‘grey zone’. The top offshore casinos, however, are a great way to make sure that you can play at licensed and trustworthy sites.

There were recent efforts by the Liberal Democratic Party to legalise casinos in Japan. The minimum legal age for the permitted gambling premises is 20 years, but if you play at an international slot site, then you should comply with its restrictions and requirements as well. Learn more about the legal online situation in our guide of the online gambling laws in Japan!

Payment Methods – Deposits and Withdrawals

You can take advantage of a wide variety of online payment methods when it comes down to deposits or withdrawals from the Japanese casino slot sites. Most slot sites in Japan support e-wallets, bank cards and direct bank transfers, as well as prepaid cards and various mobile billing methods. PayPal is among the most preferred methods, as the transactions are almost immediate, and the transaction limits are decent. Check out more about the top payment methods for players from Japan.

Sometimes, not all the methods are available for deposits and withdrawals at the same time. Sometimes, the casino cashier requires you to use the same method for withdrawal as for the deposit. In other words, you should check out the casino cashier very carefully and read all the instructions. You would like to check for minimum and maximum deposit limits, as well as the withdrawal times and if there are any additional fees applied by your card issuer or by the casino operator. That being said, let’s take a look at the most used payment method at Japanese online casinos with slots.

Top Slot Sites That Accept PayPal

PayPal is one of the most popular e-wallets around the world, and Japan makes no exception. Since Neteller and Skrill are not accepted in Japan, PayPal is your best choice if you want to deposit or withdraw from a Japanese casino site. This e-wallet offers excellent privacy and safety because your private financial and personal details remain concealed. You can find the top online slot casinos in Japan that accept PayPal in the next table.

Often, you can find the available payment methods in the footer of an online casino, but it does not include all of them. So, you should always go to the specific ‘Payments’ page or tab and see the available payment methods for you, and whether PayPal is among them. Also, please check if it is accepted for both deposits and withdrawals, because sometimes it is not. If all goes well, make sure that your transactions will be quick and effortless, and there is an awesome option for mobile billing via PayPal as well!

Best Bitcoin Slot Casinos in Japan

We should highlight this topic because Japan is one of the world’s best countries for Bitcoin payments! It recognizes Bitcoin and other cryptocurrencies as legal property under the Payment Services Act (PSA) and, therefore, the Japanese players can easily pay with Bitcoin at their favourite slot sites. There are many advantages of using Bitcoin, and its safety is second to none, however, there are not so many casino operators that accept it as a payment method. So, here is the best Bitcoin slot site in Japan for 2022:

Bitcoin Slot Sites Slots Bonus Min Deposit Max Deposit Deposit Timeframe Casino Rating Secure Link

Of course, Bitcoin has its downsides as well. It is a volatile currency, and it is not always the most trusted payment method when it comes down to online gambling. Yet, we can see a tendency for more and more JP players to prefer it over the other standard e-wallets and online payment methods.
