Japan’s online casinos are improving in leaps and bounds, thus catering to fans of gambling in various ways. As much as the top sites aim for the same thing – happy and returning customers – they take different approaches to building the perfect online casino for Japanese players. There’s no right or wrong way to go about it, you as the player have the right to choose where to start gambling and why.

How to Choose the Best Online Casino in Japan

The registration process at a typical online casino in Japan is an extremely smooth and simple process and should be identical at each site. Below, we’ve provided a step-by-step guide to signing up to ensure that your registration process is as fast and stress-free as possible.

While we’re quick to point out that the registration process is easy, arriving at the first step can be difficult. That is, finding the right casino can be tough. Thankfully, this guide is bound to make things significantly easier for you, as we explore the essential ingredients for a top casino.

One way to be sure that you’re always up-to-date with the latest advancements in online casinos and gambling in Japan is by following the news. Below, we have provided the latest news that relates to the best casinos and games in Japan.

Our Japan Casino Review Criteria

You can always join an online casino for Japanese players if it measures up to your expectations. In order to test sites fairly, we have crafted a set of criteria that takes into account all the most important factors, as well as the overlooked details that reviewers frequently miss.

In total, there are eight main factors considered when ranking the best Japan online casinos. In the below table, you have the option to jump to each factor. Alternatively, you can continue scrolling through to receive the most informed and full picture of the top online casinos Japan.

Casino Games Catalogue

To many regular gamblers, the most important element to consider before signing up with a new casino is the different games that it offers. Due to Japan’s relatively unrestricted online gaming market, we’re happy to reveal that whatever your favorite casino game is, you can find it in Japan.

This is great news to report considering that different players have varying preferences on everything from the types of games offered to the categories of slot machines on offer. In the following table, we have listed each top-ranking casino that we recommend and the number of game types it offers.

The Top Slots in Japan

It’s no secret that slots are the most popular casino games worldwide. This is evident in the fact that the best casinos in Japan offer hundreds of slots while offering far less on table games. Whether it’s old-school classic slots that you prefer or feature-packed video slots, you can find them in Japan.

If you’re playing at online slots casinos, you may want to have a look at the return to player (RTP) rates when picking games. The return-to-player rate of a slot determines how much of what is invested in the game by all players will theoretically be returned. This information can usually be found within a game’s menu.

Additionally, the volatility of a slot refers to how frequently wins are rewarded. Low volatility slots will offer frequent but smaller wins, while high volatility slots will offer large wins infrequently. With this and the feedback of Japanese players taken into consideration, here are the best online slots in Japan.

Top Japan Blackjack Offers

Out of all online casino games, Blackjack has the highest return-to-player rate. For this reason, this game is especially popular with both land-based and online gamblers in Japan. In saying that, this is a game that comes in plenty of variants that should be understood to be played successfully.

The best blackjack casinos will offer a number of different blackjack variants, which could offer features as varied as multi-hand betting, and side bets and doubling down. Keep in mind though that certain blackjack features may impact the RTP. Below, we’ve provided our pick of the best online blackjack games in Japan.

Best Japan Online Roulette

The roulette wheel is an icon of the land-based casino industry, so there’s plenty for games developers to live up to when making online adaptations of roulette. Fortunately, there are some particularly great roulette variants available to bettors in Japan that mimic the thrill of in-person gambling.

The best roulette casinos tend to offer games that replicate classic roulette styles or are bold and futuristic by making the use of modern gaming technology. Like blackjack, different roulette games offer different RTPs, with American Roulette offering lower payout rates. See below for the best Japanese roulette games.

Japan Live Casino Platforms

The explosion of the live casino industry has resulted in what is one of the most exciting advancements in the online casino industry in years. The past several years has seen a number of world-class developers who have proved themselves in the video slots arena branching out into live casinos to great effect.

This has given gamblers a growing number of great options to choose from when deciding to play live. If you’re yet to try it, live casino gambling allows you to play casino games against the dealer or other players in real-time. The best sites offer games hosted by charismatic croupiers in beautiful sets.

One downside is that live casinos require on higher download speeds. This, however, is no issue for Japan, which is renowned for its high download rates. This has made Japan the perfect market for developers such as NetEnt, Playtech and Evolution to offer their live casino games.

List of Online Casino Game Types Available in Japan

Although game types such as slots, blackjack and roulette are must-haves to be considered a top casino, we’re also interested in seeing a number of other game types provided. With some of the best international online casinos available in Japan, there isn’t much that can’t be played.

After all, in some countries, games such as bingo and baccarat are particularly popular, while online Texas Hold’em is an exciting way to improve your poker skills. We’ve listed all the different types of casino games that can be played at Japanese online casinos, most of which are available at sites we recommend.

The Importance of Good Casino Software

Have you ever noticed that many of your favorite only casino games tend to feature the same logos before they begin? These are the software developers that are behind the game. Whether they be providers Microgaming, Red Tiger Gaming or NetEnt, particular developers are loved for their unique styles, features and quality.

When judging an online casino, we’re most impressed by a website that stocks games from several developers. One reason is that most popular slots are created by numerous different developers, so the more developers featured, the more likely it is that you will be able to play these different games.

In saying this, there are some casinos that offer only one developer, whether that be Playtech or NetEnt, and are still easy to recommend. This is because the featured game developer is internationally recognized and tends to offer a wide catalogue of games built over many years in the business.

We have gauged the feedback of our Japanese readers to discover what it is they like about certain providers, whether that be different aesthetic styles or unique game mechanics. The following five developers are the highest rated providers in Japan that are represented at our recommended casinos.

Casino Safety and Licensing for Japan

The safety and security of an online casino should always be one of your highest priorities when you’re looking for a new site. This is because the high volume of financial-related traffic that online casinos host has made these sites a prime target for scammers and hackers.

Fortunately, there are several things a website can do to protect users’ data. While you can search individually for proof of encryption, responsible gambling mechanisms and fairness testing, the best way to be sure that a site has implemented these features is by checking that the casino is licensed.

As Japan doesn’t have a casino regulatory body, we suggest you rely on the licensing bodies of other gaming jurisdictions. In many cases, casinos available to Japanese customers are licensed by the Malta Gaming Authority (MGA). As you can see below, several of our top casinos have Maltese licensing.

In the above table, you will see that we have listed a few specific categories that relate to website safety and security. The first is the licensing authority. There are several global licensing bodies that have strict security standards that must be proved in order for a site to earn a licence. The MGA is one of these bodies.

Licensing requires tech audits to be held by independent testing agencies. These tests show that online casino games have not been tampered with to rig games to be further in favor of the site than advertised. IT security refers to the degree of encryption technology used to safeguard users’ connections.

It’s an unfortunate fact that some gamblers may develop compulsive gambling behaviors that can become harmful. Trustworthy websites will team up with responsible gambling initiatives and implement certain technologies to minimise the risks of problem gambling, and support those who are having struggles.

Due to Japan’s lack of a licensing body, it’s extremely important to only gamble with proven sites that offer safe and secure gaming in other markets. Every single one of our recommendations is licensed, independently fairness-tested uses encryption and has implemented a responsible gambling plan.

Japan Best Mobile Casino Options

As you’d likely be aware, mobile gambling is the most convenient and easy way to play slots and table games. This is why it’s extremely important that our casinos have either created websites that are compatible with mobile browsers or better yet, have developed mobile applications.

We understand the importance of mobile gaming, which is why all of our recommended sites are fully mobile compatible. When we’ve graded the mobile gaming options, we’ve also ensured that the platforms can be used on both iOS and Android devices, whether they be smartphones or tablets.

We’ve also ensured that most games available on the desktop version can be played on mobile. Below, we’ve listed the best mobile casinos for Japanese players.

Customer Service in Japanese

Have you ever been in a situation where you’ve needed the urgent help of a customer service representative but have had troubles reaching them, or even worse, they were unhelpful? Then you’ll know how important customer service is. Due to the financial nature of gambling, good service is particularly important for online casinos.

The best online casinos Japan offers provide a live chat service 24 hours a day, 7 days a week. In many cases, websites will offer their service in several languages, including Japanese. However, this is not guaranteed. At the very least, all of our recommendations offer customer service in English.

The Best Online Casino Bonuses in Japan

One of the biggest drawers to a new casino that Japanese players report is the size of the site’s welcome bonus. A good welcome bonus can start you off with a decent budget or a bank of free spins on slot games, which can be a great introduction to the casino’s games catalogue.

In Japan, the most common types of bonuses are deposit matches, which offer you a complete match on your first deposit/s up to a certain percentage, and free spins. Free spins are often able only to be used on a select number of games and may be awarded over several days.

With these factors considered, here are the best welcome bonuses available in Japan according to player preferences.

Above, we have ranked each bonus according to to its overall value for money. At first glance, our rankings may seem inaccurate as some may offer higher bonus amounts but are positioned lower. However, the true value of a welcome bonus can be discovered by looking into the particulars of its terms and conditions.

Top Online Casino Offers and Promotions: Terms and Wagering

Before you rush to claim a casino welcome bonus, we suggest taking a deeper look at the terms and conditions listed in the fine print. If you don’t, you run the risk of signing up to receive credits or free spins that don’t actually suit your playing preferences or habits.

Deposit matches are popular because they reward you based on what you put in. It’s common for these to come in 50% or 100% matches, though higher than 100% is possible and certainly better. Deposit match bonuses tend to be awarded in foreign currencies, although it’s not impossible to find bonuses in Japanese Yen.

Free spins may often only be for select games, though they are frequently awarded for the most popular games on the website. Free spins usually also come with certain limitations, including the value of the spins – for example, 50 cents per spin – and even the maximum amount of winnings that can be made on free spins.

In the following table, we have provided explanations for common phrases that you will see listed in the full terms and conditions of a welcome bonus. Each one of them is important to consider when grading the legitimate value of a bonus.

Common terms that are important to consider include the wagering or playthrough requirements, validity and contribution. The wagering requirement refers to how many times you need to wager the bonus before you can withdraw it as winnings. This is often as low as 20x but can be as high as 80x.

For this reason, the lower the wagering requirement, the better. This, however, may be different if games have different game contributions. The game contributions, which should be listed in the full terms and conditions, refer to what percentage betting on a game will count toward the wagering requirement.

For example, slot games often have game contributions of 100%, while table games frequently have a game contribution of around 50% or less. Therefore, if a wagering requirement on a $100 bonus was 40x, you would need to bet $4000 on a slot game to meet the requirements, and $8000 on table games.

The validity refers to how long you have to use your bonus before it expires. This could be as short as a day and up to 30 days. The importance of this will depend on how frequently you gamble, although having more time is undoubtedly better, especially when the wagering requirements are higher.

RTP: List of the Best Payout Online Casino Sites for Real Money in Japan

The return-to-player (RTP) rate, or house edge, refers to the amount that will be returned to players. For example, a slot game with a return to player rate of 95% indicates that 5% of total money spent on the game is expected, over a long period of time, to be kept as profit, while 95% will be returned to players in prizes.

The overall return-to-player rate of a website is usually determined by independent testing agencies that figure out the RTPs of every game on the site and then work out the average. Below, we have listed the average payout rates of our recommended casinos to prove that all are fair and generous.

• Casitabi – 96.0% Payout Rate
• 1xbet – 97.0% Payout Rate
• 20bet – 95.8% Payout Rate
• 22bet – 96.2% Payout Rate
• Bons – 97.2% Payout Rate
• MelBet – 96.0% Payout Rate
• 10bet – 96.0% Payout Rate
• CasinoSky – 96.0% Payout Rate
• CasinoSecret – 96.0% Payout Rate
• CasinoMe – 96.0% Payout Rate

Obviously, the higher the RTP rate, the better. It’s not unheard of for some slots to offer as little as 80% for RTPs, so the fact that all of our recommendations score around 95% or higher is a great sign. To ensure you’re playing the best odds, look at the RTP rates of your chosen games within their menus.

The Best Payment Methods for Japanese Players

To save time in the sign-up stage, we suggest checking the kinds of payment methods that the casino accepts. In our experience, the best casinos will always offer a wide selection of payment types, ranging from debit and credit cards, prepaid cards, bank transfers and our personal favorites, e-Wallets.

There are different perks to each payment method that will appeal to different bettors. Of course, some bettors may be less technologically savvy and prefer bank transfers over e-Wallets, though they will need to deal with longer transaction times. Credit cards are often the most convenient but may incur fees.

Below, we have provided a number of the most commonly available payment methods according to payment type categories. We have also provided the average transaction times and limitations.

As the table above shows, e-Wallets excel in both the transaction speed categories and are almost always available to facilitate both deposits and withdrawals at casinos. As they also often act as intermediaries between bank accounts and a Japanese casino online, e-Wallets also provide an extra layer of payment security.

It’s for this reason why we always recommend that players bet with e-Wallets. However, we must point out that in some cases, Skrill and Neteller deposits may be excluded from receiving bonuses. Additionally, PayPal may charge its own transaction fees. In either case, be sure to look into how your chosen casino handles these payments.

The Latest Gambling Trends in Japan 2024

For some time, most forms of gambling have been illegal in Japan. The only forms of legalized gambling were horse racing, some sports betting and the lottery. Japan is also home to a unique Pachinko industry, which sees players purchase balls that they can play in slot-like machines that, when jackpots strike, award more balls.

These balls can then be traded in for non-cash prizes. Over $200 billion is spent annually on Pachinko, proving just how much of an appetite there is for gambling-type games. Then, in 2018, the Japanese government legalized casino gambling at three licensed venues. It is still in the process of awarding licenses and choosing host locations.

At the moment, several international casino giants have been considered to open the casino resorts, including MGM Resorts, Wynn Resorts and Las Vegas Sands International. It may be a few more years before these resorts open, though we have little doubt that the future of gambling looks bright in Japan.

Is Gambling in Japan Legal?

Generally speaking, gambling is banned in Japan according to Article 185 of the country’s Penal Code. The Code broadly describes gambling as betting on an event that is decided by chance or accident. However, the law only covers wagering at local gambling operators, leaving the foreign-operator controlled market in a legal grey area.

For this reason, there is no Japanese licensing body that regulates foreign operators that accept Japanese customers. This is why it is extremely important for gamblers in Japan to choose foreign casinos that have earned licenses in strict jurisdictions and have earned reputations for safety and security, such as those that we review and recommend.

As the above shows, all of our recommended legal casinos in Japan have earned licensing from at least one international gaming body. Among the most reputable are the United Kingdom Gaming Commission (UKGC) and the Malta Gaming Authority. With the licensing information provided, you can view the licence details at each regulator’s website.

• Sweetspot N.V (Casitabi) – Curacao eGaming – Licence No 8048/JAZ2015-004
• Exidna Enterprises LTD (1xbet) – Curacao eGaming – Licence No 1668/JAZ
• TechSolutions Group N.V. (20bet) – Curacao eGaming – Licence No 8048/JAZ2017-067
• TechSolutions Group N.V. (22bet) – Curacao eGaming – Licence No 8048/JAZ2017-067
• Owl In N.V. (Bons) – Curacao eGaming – Licence No 8048/JAZ 2019-055
• Batnesto LTD (MelBet) – British Virgin Islands – Licence No 1810697
• Autonomode Limited (10bet) – N/A
• Sweetspot N.V (CasinoSky) – Curacao eGaming – Licence No 8048/JAZ2015-004
• Niollo B.V.R. (Casino Secret) – N.A
• Sweetspot N.V (Casino Me) – Curacao eGaming – Licence No 8048/JAZ2015-004

From what we know, no one would be facing legal consequences for gambling online in Japan, but keep in mind that the burden of choosing a trustworthy website lies on you. There are several other websites available in Japan that you can trust, though the ones we have listed are by far the best for safety, security and quality.

Casinos to Avoid in Japan

Just as it’s valuable to be aware of the best online casinos in Japan, so it is worth being aware of casinos you should avoid. After all, if you’re in the habit of reading casino reviews, there’s a chance that you may come across a recommendations website that doesn’t put as much value on things like licensing, safety or security.

The above online casinos are those that we have blacklisted. We suggest you avoid them at all costs. They have been flagged as untrustworthy for operating in markets where online gambling is illegal, for refusing to apply for licenses or for regular customer complaints. For your own safety, please avoid our blacklisted sites and stick to the ones that pass our review requirements.
