15 Best Online Casinos in Japan | Compare Top Japanese Casino Sites 2023

The good news is that you’ve actually got a huge amount of choice in this area. Dozens of off-shore casino sites happily accept Japanese punters, with many even providing Japanese-language versions of their sites. In this article, we’ll list the 15 best options of all for you. We’ll also tell you what games you can play, which payment methods you can use, and plenty more besides.

Top 5 Online Casinos in Japan Reviewed

In the list above, you can see a very wide range of top online casinos in Japan. Below though, we’ve focused on the very best of the best, and explained what makes them just so appealing.

1. Lucky Block – Overall Best Casino for Asian Players

Lucky Block home
A relative newcomer on the Asian market, the crypto online casino LuckyBlock is licensed in Curacao and regulated by the Curacao Gaming Control Board. It’s an online casino that’s rapidly gaining in popularity – and for good reason.

With its 6,000-strong game portfolio that includes titles from some of the best studios in the business, loyalty program, and a live casino that features classic casino table games and even game shows, few can hold a torch to Lucky Block in terms of the variety of games on offer.

The layout is easy to navigate on both mobile and desktop variants, with games listed alphabetically or by game studio. Microgaming, Evolution, NetEnt, and Red Tiger are just some of the lead developers dreaming up the slots and table games.

Lucky Block players can deposit using eight cryptocurrencies, including Bitcoin, Ethereum, and Dogecoin. Bitcoin payouts are the slowest and may take up to 1 hour, but the rest of the currencies take between 1-20 minutes with BNB taking just 1 minute to withdraw. Traditional card payment and wire transfers are also accepted at Lucky Block, as are Apple Pay and Google Pay.

LuckyBlock has one of the best welcome bonuses around with new players automatically qualifying for a 200% welcome bonus and 50 free spins on Wanted Dead or a Wild.

The bonus is paid in 10 installments with a maximum of 10,000 EUR available to those who deposit 5,000 EUR (or crypto/fiat equivalent). The offer is valid only on the first deposit made in the casino, with the minimum deposit required 20 EUR.

So for example, a player who deposits 100 EUR will immediately receive free spins and 200 EUR in the bonus bank. And for every €600 you play for (win or loose), you get €20 paid out to your account from the bonus bank, until you have cleared the entire €200.

What we like:

  • No fees on transactions
  • Minimum deposit is $1 or currency equivalence
  • Fast registration without KYC
  • Incredibly fast payouts

How We Rank the Top Online Casinos in Japan

As noted in our introduction, there are actually plenty of options for fans of casino games in Japan. We’ve boiled these down to 15 top options for you, with these being five of the most important factors we used to do so.

  • Online Casino Game Selection

The more games a Japanese casino site provides to choose from, the better. At the very least, we’d expect to see hundreds of slots in place, along with some table games. The more variety a brand put in place here though, the better ranking it received from us.

Of course, it’s not the quantity of games that’s important, but the quality too. This is something else we’ve been certain to gauge, testing many games for ourselves, ensuring they were provided by reputable developers, and so on.

  • Online Casino Site Usability

An online casino should be straightforward to use from the first time you load it up. This is as true in Japan as in any other country.

We’ve tested all of our recommended brands extensively, and found – in each case – that they provided a user-friendly interface. Not only that, but pages generally loaded quickly, and the platform – as a whole – was reliable.

  • Mobile Features

Japan is an extremely mobile-friendly country. As such, it’s not just a casino’s desktop site which matters, but its mobile features too.

Many of our recommended brands provide standalone mobile apps, which tend to be of an extremely high standard. For any which don’t, we’ve tested their mobile website instead, and confirmed that it’s of an acceptable quality.

  • Reputation of the Online Casino

As noted, we’ve put plenty of time into testing the 15 recommended brands ourselves. We’ve also been sure, however, to take the opinions of others into account, whether they be fellow critics or regular users. This was done to both confirm our own views – whether negative or positive – and make us aware of any issues we didn’t encounter during our own usage.

  • Online Casino Security

Before recommending any online gambling sites, we naturally want to be extremely confident that both your data and money will be secure after signing up.

We ensure this in a few different ways, including researching each brand’s track record, and checking that strong security measures are in place. Crucially, we also confirm that the brand is licensed with a regulatory body – such as the Malta Gaming Authority – which will hold it to the highest standards for security and fairness.

The Best Online Casino Games in Japan

Japanese casino players are blessed with a massive range of games to choose between. These include a series of hugely popular old favourites, and some less-heralded titles which you might not previously have tried. Let’s take a closer look at some of the best examples in each case.

Online Slots for Japan Casino Players

Slots remain the most popular games on casinos. As such, they also receive the best coverage by those casinos, by an absolute mile.

Most respectable casinos will give you at least several hundred different slots to choose between, provided by a whole range of different developers. In some cases, this number might swell to 1,000 or more. There will be a huge amount of variety within these options, regarding format, theme, complexity, stake size, and so on.

Popular Online Casino Table Games in Japan

French Roulette - One of The Popular Online Casino Table Games in Japan

‘Table games’ is a broad category, which – as the name suggests – refers to basically any game that would be played on a table in a regular casino. Just a few of the most popular examples include blackjack, baccarat, and roulette. Poker will be put into this category by some brands as well, while others will split it off into its own section. Either way, all top casino sites will give you at least a few different options here.

The Best Live Dealer Games at Japan Online Casinos

Live Dealer Games at Japan Online Casinos

For the most part, you’ll find the same selection of games with a ‘Live Casino’ section as you would within the ‘Table Games’ area. The most popular titles remain the same, such as blackjack and roulette, although you’ll also find a couple of different choices, including ‘game shows’.

The difference here, as the name suggests, is that the games are run by a live dealer, rather than the results being calculated by a computer algorithm. This helps to give a better approximation of a real-world casino, although you will tend to find slightly fewer games being offered overall.

Japan Instant Win Lottery Games

Japan Instant Win Lottery Games

For the most part, online lotteries work similarly to their real-world counterparts. You buy a digital ‘ticket’, usually with a series of numbers. A draw is held, and – if you get enough numbers correct – you get a prize. The more numbers you hit, the bigger your prize.

There are a couple of key differences here, though. Most importantly, these are ‘instant win’, meaning not only that you get the results of the lottery more quickly, but also that you’re given any winnings straight away. The results are also provably fair, with numbers being selected by a computer algorithm rather than by hand.

Online Scratchcards in Japan

Online Scratchcards in Japan

As with lotteries, online scratchards work mostly the same as the real-life version. You buy a digital card, then ‘scratch’ it to reveal numbers or symbols beneath. Get enough symbols, and you’ll instantly receive a prize.

Online scratchcards are quick to complete, and can be very fun to play. The downside, however, is that they’re still not widely available among casino sites serving Japan.

  • Recommended Brand: BONS

The Best Online Casino Bonuses and Promotions in Japan

Welcome offers deliver the biggest bonuses of all among gambling sites in Japan. With the brands serving Japan, there’s actually very little variety among the promotions you can get. They’re almost all of the same type, with only the amounts and T&Cs differing between them.

Let’s see what that offer type involves, and investigate the rewards you can receive.

Deposit Match

This offer type is absolutely dominant on Japanese casinos. In fact, you’ll find some variation of it on almost every brand. That’s certainly not a bad thing though, because these promotions deliver seriously big bonuses.

As the name suggests, they involve the casino ‘matching’ your first deposit. The amount will typically be anything from 100-200%, and the match will be delivered as a bonus, rather than cash. This can then be used to place wagers, in place of your regular balance.

There is one major drawback here, however – the infamous ‘rollover requirement’. This means that any winnings from your bonus cash must be wagered through a certain number of times. If you win 1,000 JPY, for example, and there’s a 5x rollover, you must stake at least 5,000 JPY on games before withdrawing your winnings.

  • Recommended Casino: TigerRiches100% Casino Welcome Bonus Up To ¥‎100,000

Free Spins

Along with the aforementioned bonus money, this is the other type of reward you’ll receive from online casinos. Some brands will bundle free spins together with a deposit match welcome offer, while others will allow you to claim them via ongoing promotions.

Again, the name is self-explanatory here. These are simply tokens which you use for spins on certain slots, instead of spending your real money. Be aware that certain T&Cs will apply here though, with a cap on your winnings being the most common.

  • Recommended Casino: Wazamba – 100% Match Up To 500 EUR, Plus 200 Free Spins

Comparing the Top Online Casinos in Japan

We’ve covered the main types of welcome bonuses you can get from Japanese casinos above. Now, it’s time to find out what you can specifically receive from our 15 recommended brands. The table below shows you exactly that, so you can identify the bonuses in which you’re most interested at a glance.

Is Online Gambling Legal in Japan?

The Japanese government has a confusing stance towards casino usage. Since 2018 it has been legal to use a land-based casino within theJapan flag icon - Country flags country. It remains illegal, however, to use casinos online. As such, there are obviously no domestic casino brands in Japan.

Technically, if you were ‘caught’ using a foreign casino site in Japan, you could be given a petty fine. In reality, similar to Singapore online casinos, this law simply isn’t enforced by the authorities. Ultimately, therefore, while you’ll technically be breaking the law by gambling online in Japan, there’s almost a 0% chance you’ll be punished for doing so.

Online Casinos vs Land-Based Casinos in Japan

As noted above, it has actually been legal to bet at land-based casinos in Japan for a few years now. Unsurprisingly, quite a few brands have already taken advantage of this by setting up shop in the country.

As such, you have two clear choices about how you play casino games in Japan: in-person, or online. Let’s see how the two compare and contrast in a handful of key areas.

Convenience

This is one category in which online gambling in Japan wins hands-down. In fact, for most bettors, it is the main reason to use digital casinos over their real-world counterparts.

To use a land-based casino, you obviously need to go there in the first place. Depending on where you’re based, this could mean quite a bit of travel. Even if there’s a casino near you, it still takes some time to get there, get set up, and start playing.

None of this is the case with online casinos. You simply open your laptop or unlock your phone, log onto a site, and start playing straight away. You can do this wherever you are, whenever you like.

Winner: Online Casinos

Game Selection

You certainly won’t lack choice at any respectable land-based casino. The vast majority of them will provide you with plenty of slots and table games to choose between.

When it comes to the sheer variety within these categories, however, online casinos are once again superior. They will always provide hundreds more slots than you’d find in a brick-and-mortar location. While the same table games will be in place, playing online will usually offer a few different versions of each game; instead of simply playing blackjack, for example, there might be several different kinds of blackjack you can choose between, which differ in theme, buy-in amount, and so on.

Winner: Online Casinos

Atmosphere

This one should be a major consideration when choosing whether to gamble at real-world or online casinos. Some bettors like the feeling of a physical casino, whether for the camaraderie with other players, the interaction with the dealers, or – quite simply – the bar. Others prefer the privacy and more relaxed nature of an online casino. Your preference is completely subjective, of course, but it’s something you should think about in advance.

Winner: Tie

How to Win at the Top Real Money Online Casinos in Japan

Playing with online casinos in Japan can be a lot of fun, if you approach it the right way, but there’s never a guarantee that you’ll make a profit. Here are some of the best measures you can take to boost your chances, though.

Tip 1 – Measure Your Stakes

Everyone will have a different budget for their casino gambling. Make sure you identify exactly how much you’re willing to wager per day, week, or month ahead of time, and stick to this figure religiously, whatever happens.

Tip 2 – Use Those Bonuses

Whether they’re welcome offers or ongoing promotions, all casino special offers have one thing in common: they help your cash balance go further. Use these whenever and wherever possible (assuming you’re getting a good deal, of course) to increase your long-term profits.

Tip 3 – Create Multiple Accounts

Creating accounts with multiple casinos will let you trigger a series of welcome offers, which give you the biggest rewards of all. Not only that, but you’ll also have instant access to any new ongoing promotions, and get a better chance at having access to all the latest games which are released.

Tip 4 – Learn From the Experts

Whatever your games of choice – whether poker, baccarat, blackjack, or anything else – you’ll find a huge amount of information online to help you. Devour as much of this as possible, and learn all the basic strategies and most important tips before committing any money to your gaming.

Tip 5 – Practice Makes Perfect

Don’t expect to ‘dominate’ your online casino straight away. Start slowly, and build up as you grow more confident. You’ll find that many games offer a demo mode, and we’d recommend getting comfortable with these before committing any real-money stakes.

The Top Online Casino RTP Slots in Japan

As touched upon earlier, slots remain the most popular games on online casinos, and this is as true in Japan as anywhere else. You’ve got thousands of options here, and sorting through them all can be intimidating to say the least.

One quick and easy way to gauge a game’s quality, however, is to check its RTP. This stands for ‘Return to Player’, and gives you an idea of how much money you might realistically win. It’s expressed as a percentage, which indicates your theoretical winnings if you played the slot long enough. With an RTP of 98%, for example, if you staked $1,000 over the long run, you should get $980 back.

Here are 10 of the best slots among Japanese casinos, regarding their RTP. You can also see short reviews for the three top options of all below.

Slot Developer RTP Recommended Site
Ugga Bugga PlayTech 99% LuckyBlock
Marching Legions Relax Gaming 98% BC.Game
Mr Macau BetSoft 97% BetOnline
Fancy Fruits Gamomat 96% Mr Play

Toad’s Gift Playtech 96% Spin Samurai
Starburst NetEnt 96% Casumo
Thunderstruck II Microgaming 96% Jackpotcity
Lady of Fortune Play’n Go 96% Wazamba

1. Ugga Bugga

Ugga Bugga - Online Casino RTP Slot in Japan

This is the definition of a classic slot. Created by industry giants Playtech Software, it was released all the way back in 2013 but remains immensely popular to this day. One of the main reasons for this, apart from it being very easy to play, is the sky-high 99% RTP.

2. Marching Legions

Marching Legions - Online Casino RTP Slot in Japan

Marching Legions is a slot with an ancient theme, but there’s absolutely nothing outdated about its excellent 98% RTP. It was developed by Relax Gaming, and features a whopping 243 different ways to win, offering excellent long-term replayability.

3. Mr Macau

Mr Macau - Online Casino RTP Slot in Japan

Created by Betsoft Gaming, Mr Macau takes you on a journey to one of the world’s most famous casino destinations. It’s a five reel, 20 payline game which can deliver some seriously big returns, with a potential payout of over 4,000x your original stake.

How to Sign Up to an Online Casino in Japan

The international casinos which accept Japanese bettors tend to be extremely easy to use. You can usually sign up and start playing within barely a few minutes, with these being the handful of steps you must take.

Step 1: Choose a Reliable Online Casino Site

Head to the top of this page and pick one of our 15 recommended online casinos, then load up their home page on either your desktop or mobile device. We’ll assume you’re using Spin Samurai for the purposes of this guide, but the process will be largely the same with our other brands.

Spin Samurai Online Casino Japan - Home Page

Step 2: Create Your Betting Account

Look for the ‘Register’ or ‘Sign Up’ button on the home page of your chosen brand, click it, and complete each of the sections in turn. This will involve providing personal information (such as your date of birth and address), and deciding your account details (namely your username and password).

Step 3: Make a Deposit

Log into your newly-created account, and hit the button reading ‘Cashier’ or ‘Deposit’, usually located in the top-right of your screen. You’ll now see a list of your available options. Pick one and enter the amount you wish to deposit, then provide the necessary details and confirm the payment.

Step 4: Start Playing Your Favourite Online Casino Games

This is the fun part. Now that your account has been funded, you can head back to the home page and choose from the wide range of games that are available to you. You’ll need to place a stake for every game you play, which will be deducted from your cash balance, but will receive any winnings instantly.

Step 5: Verify Your Identity

Before making any withdrawals, almost all legitimate Japanese online casinos will need you to verify your identity. Fortunately, doing so is extremely easy. Simply take clear photos of a piece of photo ID (e.g. a passport), and a document proving your address (like a utility bill). Now submit them to the support team, either via a document uploader tool or live chat, and wait for your account to be verified.

Step 6: Request a Withdrawal

It won’t usually take longer than a day, at most, for your account to be verified. Once it has been, you’re free to start making withdrawals. To do so, simply click the ‘Cashier’ button again, choose the ‘Withdraw’ option, and pick a withdrawal method. Enter the amount you wish to take out of your account, along with any necessary payment details, and confirm the transaction.

Comparing Payment Methods at Japan’s Top Online Casinos

The days of being limited purely to bank transfers and debit cards to fund your betting accounts are thankfully over. Nowadays most online casinos will offer you a variety of ways to do so, and this is certainly the case with those serving Japanese customers.

Alongside the aforementioned ‘big two’, the vast majority of casinos will also let you choose between a few different eWallets, such as PayPal, Neteller, or Skrill. Prepaid cards are also common, and some off-shore brands will even let you use cryptos.

While no casinos are based in Japan itself, for legal reasons, many of our recommended brands will still let you make payments directly in yen. Unfortunately, though, very few of them actually offer any Japanese-specific payment methods.

What is the Best Online Casino in Japan?

Using an online casino in Japan might technically still be against the rules. Don’t worry for a second, though, because this won’t actually stop you from playing any of your favorite games. The rules themselves aren’t enforced, and there are dozens of great international online brands that are more than happy to accept Japanese players.

We’ve given you 15 excellent examples in this article. For our money, Spin Samurai is the very best of the best right now, with a great selection of games housed in an excellent user interface. Naturally, the cool Japanese theme doesn’t hurt either. The other 14 casinos also have their own benefits though, and – whichever one you go with – you’re sure to find a modern, safe, and user-friendly experience.
