The Top Online Casino Bonuses Reviewed

Every major betting site serving Japan will provide a few casino bonus options, but not all of these are created equal. In fact, they vary wildly in both the value they represent, and their general quality. The 10 online casinos we’ve picked out above all excel in this respect, with these five brands being the very best of the best.

1 – 1xBet – 100% Deposit Welcome Bonus Up To ¥194,000

1xbet online casino bonus

Since launching in 2007, 1xBet has gone on to make a huge name for itself, with Japan being just one of the many countries it serves around the world. In addition to a packed-out sportsbook section, 1xBet also features an online casino with thousands of games available to choose between. 

The experience here is taken to a new level by the breadth and quality of the casino bonus options. Even after triggering the enormous Deposit Match welcome offer, you’ll still be able to choose between plenty of other deals. These include reload bonuses, jackpots, bonuses on your winnings, and more. Better still, the entire site is available in Japanese, and 24/7 customer service is provided.

What we like:

  • Japanese-language site available
  • Huge welcome bonus
  • Massive range of casino games

What we don’t:

  • User interface could certainly be streamlined

2 – Spin Samurai – Get More Than €800 + 75 Free Spins

spin samurai online casino bonus

Spin Samurai creates an incredible first impression, with one of the coolest user interfaces of any online casino right now. This platform doesn’t just look great, though – it’s also extremely straightforward to navigate, on both a desktop and mobile device, with the hundreds of different slots being incredibly easy to browse and access. 

Spin Samurai also excels when it comes to casino bonus deals. Newcomers can actually get three separate deposit matches here, and there are separate deposit match deals for existing customers. Add in a strong VIP program, plus an entire Japanese-language version of the website, and there’s plenty to like here. 

What we like:

  • Brilliant user interface
  • Great range of slots
  • Multiple deposit matches for new customers

What we don’t:

  • Live chat could be more responsive

3 – 22Bet – 100% Deposit Match, Up To 40,000 JPY

22bet online casino bonus

Like 1xBet, 22Bet is a ‘jack of all trades’ betting site. Along with an enormous sportsbook, and separate sections for the likes of lotto games, you’ll also find a jam-packed online casino here. Many of the world’s most celebrated betting software developers have been enlisted to provide the titles, and both the computer-run and live dealer games are excellent. 

Most importantly for our needs in this article, 22Bet also provides you with plenty of good casino bonus options. There are deposit match deals for both new and existing customers, plus a separate offer which you can trigger for free spins every single day, and a solid VIP program to reward your ongoing loyalty. 

What we like:

  • Excellent mobile apps
  • Very good live dealer games
  • Daily free spin casino bonus

What we don’t:

  • Not the fastest payment processing around

4 – BK8 – 200% Deposit Match Up To ¥67,000

bk8 online casino bonus

Early on, BK8 made the choice that it would focus entirely on the Asian market. And, while it doesn’t technically have a Japanese-language version of the site available, bettors from Japan are still more than welcome to sign up and start playing here. 

Do so, and you will become part of an enormous online casino, split across several different smaller websites. You’ll also get access to one of the best selections of casino bonuses around. Along with a VIP program, this includes a daily reload bonus, a cash-back deal, win streak bonuses, and more. 

What we like:

  • Accepts cryptocurrency payments
  • Plenty of big bonuses available
  • Huge selection of casino games

What we don’t:

  • Multi-site layout can be confusing to newcomers

5 – Lucky Niki – 100% Match Up To 100 EUR, Plus 30 Free Spins

lucky niki online casino bonus

Like Spin Samurai, Lucky Niki has committed completely to a Japanese theme. Not just that, but you can deposit and play directly in JPY on this casino site, and the entire platform is available in Japanese as well as English. 

Naturally, there’s also a great selection of online slots, jackpots, and table games to choose between, plus several great casino bonus deals to take advantage of. After claiming your welcome package, which includes both a deposit match and free spins, you can keep the bonuses coming with plenty of daily promotions, which are only available to existing customers. 

What we like:

  • Deposit and play directly in JPY
  • Cool, user-friendly interface
  • Several different daily promotions available

What we don’t:

  • No mobile app available

Different Types of Online Casino Bonus

Welcome offers deliver the biggest bonuses on online casinos, by far, and that’s as true in Japan as in any other country. Unfortunately though, Japanese punters don’t have much choice when it comes to these deals. Every top site we came across provided the same type of casino bonus for new customers, which you can learn all about below. 

Deposit Match

This offer type is completely dominant among Japanese online casinos. That’s actually not the worst thing in the world though, as deposit match deals tend to deliver extremely big rewards. 

They also happen to be very easy to both understand and trigger. After signing up to a casino site, you make your first deposit on the platform. The brand will then match that deposit in the form of a free bet, up to a certain maximum amount. 

The size of the match will also vary from platform-to-platform, but it’s rare to get less than a 100% match, which means that your spending power is immediately doubled. With 1xBet, for example, you can deposit anything up to a mighty ¥194,000, and get the same amount gifted to you as a bonus token. 

Terms and conditions naturally apply to deposit match deals, which we’ll explain shortly. For now, here are three of the best such welcome offers you can use.

Top 3 Deposit Match Deals in Japan

BK8 JP logo 200% Deposit Match up to ¥67,000 Get Offer
Wazamba JP logo 100% First Deposit Match up to ¥65,000 Get Offer

Free Spins

It’s extremely rare to find a Japanese casino site which only gives you free spins when you sign up. Many brands, however, will provide these as an added benefit to their regular welcome offer, which – as noted – will usually be a deposit match. On Spin Samurai, for example, you can get 75 free spins on top of the 100% first deposit match. 

Free spins are digital tokens, which you can use instead of your cash balance to play slots. They will only be eligible on certain titles, however, and any winnings you get will likely be subject to a wagering requirement.

Comparing the Top 10 Casino Bonus Offers

As in all areas of online betting sites, there’s no such thing as the ‘perfect’ casino bonus. Even among the best of the best – which we’ve brought you in this article – you’ll find significant variety in both the values involved, and the terms and conditions which come attached. Below, you can get a quick and easy look at how all of our recommended casino bonus sites in Japan stack up, in both of these key areas.

Which Payment Methods Can I Use for Online Casino Bonuses?

Online casinos in Japan nowadays tend to offer you an excellent choice of payment methods. These go far beyond the traditional options, to also include the likes of eWallets, prepaid cards, and cryptocurrencies. Some sites – including several of our recommended brands – will also allow you to deposit and play directly in JPY, rather than converting from EUR or USD. 

With that said, not all of these methods are suitable when you’re trying to use a casino bonus, as you can see below. 

Debit Card

Visa and Mastercard are almost universally accepted by Japanese casino sites. They are also safe, and allow instant deposits and fairly quick withdrawals.

Most importantly for our needs, debit cards are almost always compatible with casino bonus offers. That goes for both sign up deals, and ongoing promotions. For all these reasons, if you’re just getting started in casino betting, we’d recommend using a debit card if you can. 

Bank Transfer

Along with debit cards, this is the other major traditional payment method. It also enjoys excellent coverage among Japanese casino sites, with most either letting you wire them money directly, or by using a third-party service like Trustly. 

Like debit cards, bank transfers are compatible with the vast majority of casino bonus deals. The only drawback is that – while deposits tend to be fast – bank transfer is one of the slowest payment methods around for withdrawals. 

Other

Each of the other three major payment methods – eWallet, prepaid card, and crypto – has its own advantages. These tend to be extremely quick and easy to use, and offer more anonymity than either debit cards or bank transfer. 

Unfortunately, these methods are almost always incompatible with welcome offers on online casinos. As such, you’ll need to use an alternative option to grab those sign up deals in the first place, and can then use these methods for subsequent deposits and withdrawals. 

Online Casino Bonus Key Terms and Conditions

Before claiming any casino bonus at all, it is crucial that you check out the corresponding terms and conditions in full. ‘Reading the small print’ might sound boring, but – if you fail to do so – you could end up wasting both your time and money. 

When attempting to get your hands on a casino bonus in Japan, these are some of the key T&Cs to look out for.

Minimum Amounts

When first triggering a welcome offer, you must ensure to match the minimum deposit amount with your very first payment. As noted in the previous section, you should also be sure to use an eligible payment method here. 

Maximum Amounts

All deposit match welcome offers – which is the main type you’ll find in Japan – will come with maximum limits on the bonuses you can get. Technically, you can deposit more than this into your account with your first payment. Be aware, however, that not all of this will be matched. 

Game Eligibility

Whenever you receive free spins from a welcome offer, you will only be able to actually use them on certain games. These will be noted within the T&Cs for the offer, as will the monetary value of the free spins you’ve been given. 

Rollover Requirement

This is arguably the most important restriction of all. 

Whenever you use a deposit match welcome offer, the bonus you receive will be subject to a rollover (or ‘wagering’) requirement. This means you must bet through the deposit and/or bonus amount a certain number of times. If you claim a 500 JPY bonus, for example, and there’s a 3x rollover requirement, you must bet through 1,500 JPY. 

Any bonus winnings will not be converted to cash, and will therefore be ineligible for withdrawal, until this requirement is satisfied. 

How to Profit from Online Casino Bonuses in Japan 

However good a casino bonus is, it won’t automatically guarantee your success on a site, nor that you’ll even make any money at all. Instead, you must be smart in how you approach these deals, in order to get the most possible value out of them. Here are five tips to help you do just that. 

Tip 1 – Read the Small Print

We really can’t stress this strongly enough. It is absolutely essential that you check out the T&Cs for any casino bonus – in full – before attempting to claim it. Fail to satisfy any of the requirements – by failing to meet the minimum deposit amount, for example, or using an ineligible payment method – and you will immediately forfeit the entire casino bonus. 

Tip 2 – Shop Around

Nothing comes for free on betting sites, and this is obviously true for special offers too. To claim a casino bonus in Japan, you will first have to commit some of your hard-earned money. 

As such, it’s worth spending a little time to shop around and pick the most suitable deals for your needs. If you prefer a slow and steady approach, prioritise casinos which give you rebates on your losses. If you’re more of a high-risk, high-reward bettor, look instead at brands which give you bonuses on your wins, or reward you for putting win streaks together. 

Tip 3 – Open Multiple Accounts

As noted earlier in this article, when it comes to online casinos, welcome offers deliver the biggest bonuses by far. As such, many experienced players will simply go around different casino sites, create an account, claim and use the bonus, withdraw any winnings they receive, and move on. 

While this can be time-consuming, it is a perfectly legitimate strategy for profiting from casino bonus deals. After all, there’s no rule saying you need to commit to one or two Japanese casino sites at a time. 

Tip 4 – Be Smart

Whenever you receive a casino bonus, it can be tempting – especially if you’re an inexperienced player – to use it straight away. It’s undeniably exciting to see that token in your account, after all, and giving into this excitement is easily done. 

Instead, we’d recommend staying patient here. Don’t think of your casino bonus as a ‘free hit’ to be wasted. Instead, think of it as a golden opportunity to rack up some additional profits, without risking your cash balance. 

Stick to games you already know and are comfortable with, rather than throwing your bonus away on a game you know nothing about. Likewise, if you’re playing a game which requires some skill and judgement – such as poker or blackjack – take things slow and steady, rather than blowing your casino bonus on a risky play. 

Tip 5 – Think Long-Term

In this article, we’ve concentrated mostly on welcome offers which can only be claimed by new customers. Even the best sign up casino bonus deals will only last a short amount of time, however. As such, if you’re looking for a Japanese casino to keep you entertained over the long haul, you should definitely prioritise ongoing promotions. 

Ongoing deposit matches are one of the best such deals you can get. Other tasty deals for existing customers include free spin offers and cash rebates, and a good VIP program will recognise your ongoing loyalty with a whole range of different rewards.

How to Sign Up for an Online Casino Bonus

Modern-day casino sites in Japan are extremely easy to both sign up for and use, even if you’re a complete novice in online betting. After picking a brand, you’ll be able to create an account within a couple of minutes, and triggering the welcome offer tends to be extremely straightforward too. 

To help you on your way though, here’s a quick guide on how to claim a casino bonus in Japan. We’ve used the user-friendy Spin Samurai as our example site here. 

Step 1 – Visit the Home Page

spin samurai registration 1

After picking your casino of choice (in this case, Spin Samurai) simply head to the home page of the site. Alternatively, you can download the mobile app instead, on which you’ll be following a very similar process.

Step 2 – Create an Account

spin samurai registration 2

Once you’re on the home page of your chosen brand, click the ‘Sign Up’ or ‘Register’ button, which will usually be located in the top-right of your screen. 

After that, simply follow the site’s instructions. This will involve providing some personal information (such as your name and home address), and setting your account details (including a username and password). 

Once all that’s done, click the ‘Create Account’ button to finish the registration process.

Step 3 – Make a Deposit

spin samurai payments

With your account created, it’s time to make your first deposit. Log in, then hit the ‘Deposit’ or ‘Cashier’ button, which is also usually found in the top-right. 

You should now pick a payment method which is compatible with the welcome offer, and enter a value which meets or exceeds the minimum amount. Afterwards, enter the requisite account details, and confirm your payment. 

Step 4 – Claim Your Bonus on the Casino

If the online casino requires you to claim your bonus manually, now is the time at which to do so. In most cases, however, you’ll automatically be given your deposit match after making that initial deposit. 

If you’re confident that you’ve followed the T&Cs, but your bonus still hasn’t appeared, we’d recommend getting in touch with the customer service team immediately. 

Step 5 – Use Your bonus

spin samurai registration 3

As noted, your casino bonus should be in your account by this stage. Now, it’s time for the fun to begin. Head to the casino area, pick a title you enjoy playing (and which is compatible with the welcome offer), and load it up. Instead of using your regular account balance, however, you should be able to use your bonus instead. 

Step 6 – Complete the Rollover Requirement

After using your bonus, you’ll hopefully have some winnings in your account. These must be bet through a certain number of times, however, before they’re actually converted into cash. 

To complete this wagering requirement, head back to the casino section and place stakes matching the necessary amount. 

Step 7 – Withdraw Your Winnings

spin samurai withdrawals

Before withdrawing your winnings, you’ll need to verify your identity. This is easily done though, by simply providing clear images of at least two pieces of ID. One should show your face, and the other should display your residential address. 

Once this is done, you’ll be free to withdraw money from your account. Be aware that most Japanese casino sites operate a ‘closed loop’ policy here, meaning you must withdraw using the same method you used for your initial withdrawal. 

Final Thoughts

If you’re looking for a casino bonus in Japan, there are plenty of great options out there. Despite the government’s unfriendly attitude towards online betting, dozens of offshore brands are still happy to take your wagers. Almost all of these will provide at least one casino bonus for new customers, and many will also give you ongoing promotions.

After reading this article, you know about the 10 best sites on which to claim a casino bonus, and how to go about doing just that. All you need to do now is pick one of our recommended brands, claim that casino bonus, and start having fun.
