Stay tuned to the end of this guide, because we will touch on a wide variety of essential topics, such as mobile compatibility, available payment methods and the RTP percentage of the best Japanese online slots.

Top Online Slot Games to Play for Real Money in Japan

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. Either way, some online casino slots are always more preferred than others and it all depends on your particular taste. Here are the top 10 online slot games that Japanese players can pay for real money:

  1. Game of Thrones 🥇 Microgaming (RTP 95.07%, Best Movie-Themed Slot)
  2. Book of the Dead 📖 Play’n GO (RTP 96.21%, Best Egyptian-Themed Slot)
  3. Wild West 🔫 Swintt (RTP 92.69%, Top Slot with a Medium Variance)
  4. Dragons of the North 🐉 PariPlay (RTP 94.49%, Most Appealing Jackpots)
  5. Great Rhino Megaways 🦏 Pragmatic Play (RTP 94.69%, Famous Megaways Slot)

  10. Maximum Reels 👁️‍🗨️ Cayetano (RTP 95.08%, Best for High Maximum Win)

Of course, many of these games can be played at Japan’s high payout slot casinos and we will give you some very hot recommendations as well. The higher the payout (or the RTP%), the better. This means that you can receive a better payback percentage from your wagers, measured per spin and on average. Typically, this percentage for the video slots ranges between 80% and 96%, however, you can find slots with up to 99% RTP!

Top Online Slot Casinos with High Payout

So, let us present to you the best slot sites in Japan where you can play games with very high RTP rates. Each of these sites below offers games with a very high RTP of over 96%. 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.

The listed high payout slot sites are suitable for both high rollers and low-stakes players, so there is a perfect slot for everyone’s preferences and are present in most of the high roller casinos in Japan. You should also try playing the best Japanese online slots with a bonus. The best slot bonuses in Japan offer exactly what you are looking for, especially if you are a new player who plays for the first time.

Top Online Casinos That Offer Slot Tournaments

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:

Online Casino Free Slot Tournament Prize Safe Link
Cash Days Tournament $60,000 Prize Pool Enter Here
Playtech Tournament 10,000€ Prize Pool Enter Here

There are many benefits of playing free tournaments. For instance, the two Japanese online casinos with slots tournaments that you can find in the table above also offer huge prize pools and juicy welcome bonuses for first-time players. At Unibet, you can find a special tournament that is valid only for Playtech games, so it is especially convenient if you are a fan of the games from this software provider. We recommend you check out the terms and the conditions of each slot tournament very carefully before you enter because it is important to know all the details in advance. 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 2021:

Slot Casino Welcome Bonus Min. Deposit Wagering Requirements Validity Safe Link
5000€ + 50 Free Spins 60€ 35x 30 Days Claim Bonus
Up to 1,500€ + 100 Free Spins 60€ 35x 3 Days Claim Bonus

100% Up to 200€ + 100 Spins 10€ 35x 21 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.

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.

Online Slot Casino Credit/Debit Card e-Wallets Prepaid Cards Other Deposit Limits Withdrawal Limits
MasterCard, Visa ecoPayz, MuchBetter AstroPay Card 5€ – 10,000€ 10€ – 10,000€
MasterCard, Visa PayPal, MuchBetter, ecoPayz AstroPay Card 10€ – 10,000€ 15€ – 10,000€

MasterCard, Visa PayPal Paysafe Card 10€ – 50,000€ 20€ – 5000€

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 2021:

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.
