Japan is a country steeped in rich history and culture, with its incredible cuisine and technology wowing visitors who head to the likes of Tokyo and Kyoto.
You may not know it, but Japan also has a vibrant casino industry, with millions of players enjoying games such as pachinko, mahjong, and slot machines. However, the legal landscape for online casinos in Japan can be challenging, making it difficult for players to find safe and reputable options.
That's where Casino Guru comes in. Our expert team has carefully researched and reviewed the top online casinos in Japan in 2025, so you can enjoy a secure and enjoyable gaming experience from the comfort of your own home.
On this page, you'll find a curated list of relevant gambling sites, whether you're searching for a live-dealer, crypto-friendly or mobile casino Japan has to offer. Just let our review, rating, and filter system lead the way.
Online gambling in Japan is a complex and often contentious topic. Most forms of gambling are illegal, and this prohibition is included in the national Criminal Code. Betting on horse racing, boat racing, and bicycle racing is allowed, as well as certain lottery games. However, casino gambling, including online casinos, is illegal.
Despite this, the government doesn't prosecute players for betting online, according to various sources, nor does it ban offshore casinos from offering their services to Japanese casino players. There are numerous domestic gambling sites that operate in the country's black market, too, but we would advise players to steer well clear of these.
In recent years, the Japanese government has taken steps to crack down on these black-market sites, passing legislation to impose stricter penalties on those offering such illegal betting.
One area where online gambling has been able to prosper in Japan is pachinko, a popular form of gambling that resembles a combination of pinball and slot machines. Pachinko parlors have been able to skirt the country's strict gambling laws by offering prizes that can be exchanged for cash outside of the parlor.
Whether the rest of the online gambling sphere will start to benefit in the future, though, is very uncertain. Betting in general is frowned upon by many sectors of Japanese society and it's difficult to see how the industry will evolve in the coming years.
If you're a player there and would like to see how to locate the best online casinos in Japan (these will all be offshore sites), then continue reading to find out how you can do this.
How to choose the best online casino in Japan for you
When it comes to choosing the best online casino in Japan, it's important to bear several factors in mind. Has it got a reputation for paying out wins? How many complaints does it have, and does it tend to resolve them? Does it have fair terms and conditions?
To make this process easier for you, Casino Guru provides a variety of filters and sorting tools that can help you find the best online casinos in Japan according to your preferences. If you've just arrived here and are not sure what to do, then follow this checklist to put yourself on the right path.
Check the Safety Index – Casino Guru's expert team awards each site a Safety Index that is made up of the factors mentioned above, plus several more. Obviously, the higher the Safety Index, the better the chance of you having a positive experience. We advise you to start with the sites at the top of the list with the 'Recommended' tab selected.
Use the filters – If you'd like to have fewer options to choose from, Casino Guru's filters allow you to narrow down your search. The most popular filters are 'Casino Games,' 'Payment Method,' and 'Game Provider,' but you can also see the sites with a certain 'Withdrawal Limit' or 'Licensing Authority' by selecting the relevant section.
Reorder the list – Casino Guru's sorting tools allow you to reorder the list of casinos based on different criteria. For example, if you select the 'Recently opened' sort, new casinos will appear at the top of the list.
Read the reviews – Our reviews are packed full of information that you can find out in a minute or two of reading – way faster and safer than signing up to the site to try it for yourself. Our expert team's judgement will put you on the right path.
Check out different casinos – If you have the time, it's also a good idea to visit two or three of the best online casinos in Japan by clicking on the 'Visit Casino' button and see whether you like them before deciding where to sign up.
Japan online casino bonuses
Online casino bonuses are much talked about in the internet gambling world as they offer something that traditional casinos don't: free spins or extra credit. Casino bonuses are generally intended to attract new players, but there are also some available for the already registered ones.
What you must do to get one depends on the type of casino bonus. As the name suggests, you have to make a deposit to get a deposit bonus. This type of bonus is often worth more than a no deposit bonus, but the advantage with the latter is that you only have to sign up to claim it.
However, like with online casinos in Japan, it's important to find the best possible bonus for you. Casino Guru provides you with various filters that you can use to track it down. For example, you can adjust the list according to bonus type or value, to name just two options.
Note: Once you have the bonuses with your preferred features, it's important to read the terms and conditions carefully. These will tell you what you need to do in order to claim the bonus and any potential winnings from it, such as wagering requirements (WR) and minimum deposit amounts.
Some bonuses may also require you to enter a bonus code in order to claim them. This is common. Just follow the instructions in the information box to do this.
If you do the above correctly, then you'll be well on your way to finding the best online casino bonuses Japan has to offer.
