Although our #1 overall selection this time around was Lucky Niki; we’ve got 14 runner-ups with their own, unique list of standout features.

Let’s take a closer look!

The Best Online Casinos in Japan

1. Lucky Niki – Best Online Casino in Japan Overall


  • Over 3,400 online slot games
  • Solid VIP Program
  • 100 free spins with first deposit
  • Reasonable 30x playthrough
  • Fast, fee-free withdrawals


  • Deposit bonus isn’t very competitive

Lucky Niki is the best online casino site for Japanese gamblers looking to play online. They’ve knocked their competition out of the park with 3000+ online slots, around 50 virtual sports betting options, and over 150 live dealer games. When you sign up now, you’ll get 150 free spins with your first deposit.

Gaming Variety: 4.5/5

When you sign up with Lucky Niki, you’ll never run out of games to play. Sports bettors and traditional online gamblers alike can enjoy everything their casino library has to offer here.

You’ll find over 3,000 high-quality online slots and more than a few progressive jackpots to use your free spins across.

Skill gamers will further appreciate Lucky Niki’s ample selection of table games. You’ll find several variants of live dealer baccarat, blackjack, roulette, Texas Hold’em, and poker through their live casino. You can also play through 4 types of video poker here.

Additionally, when you feel like you need a change of pace, 50 virtual sports betting options are waiting for you. You’ll have access to golf, darts, horse racing, American football, wrestling, boxing, basketball, fishing, cricket, and much more.

In short, there isn’t much you won’t find with Lucky Niki.

Bonuses & Promos: 4.2/5

Their welcome bonus is geared towards satisfying slot players; but we think everyone can appreciate receiving 150 free spins to use across any of Lucky Niki’s extensive slots library.

Their initial deposit match could be a lot more competitive, though. When you make your first deposit of at least $20, you’ll qualify for a 100% bonus up to $100. The whole package is up for 3 deposits and gives you a total of $350.

Your free spins and deposit bonus both come attached to a very reasonable 30x playthrough.

Their VIP Program is also one of the most detailed and player-friendly loyalty programs we’ve come across. As you gain more loyalty points and level up with their site, you’ll qualify for special monthly bonus offers, higher deposit limits, and even faster payouts.

Banking Options: 4.1/5

Players who sign up with Lucky Niki can take advantage of several secure payment methods through their site. Additionally, we liked their low deposit limits. Even if you put down as little as $20; you’ll get the same 150 free spins as everybody else.

You’ll be able to make your deposits and withdraw your winnings through credit card, ecoPayz, iWallet, Neteller, and Skrill.

Although we believe their banking menu is comparatively limited; they manage to take everyone’s payment preferences into account here.

Finally, you can expect blazing-fast, fee-free payouts here. Withdrawals made through Bitcoin, ecoPayz, Neteller, and Skrill take a mere 24 hours to process and deliver; while all credit card payouts take 48 hours to clear.

Mobile Compatibility: 5/5

Lucky Niki hosts a native casino app for iOS and Android devices. You’ll be able to enjoy their full selection of slots, virtual sports betting options, and live dealer table games from the palm of your hand.

As far as casino software goes, we liked how their app was structured.

We found it easy to place bets with one click, add money to our casino wallet, and scroll through their entire selection of mobile-optimized provisions while on-the-go.

2. National Casino – Best Online Casino in Japan for Gaming Variety


  • 4,200+ online casino games
  • Over 100 casino software providers
  • Around 500 live dealer provisions
  • Native mobile app offers full casino library
  • Comprehensive banking menu


  • High 40x playthrough

National Casino is our top pick for gaming variety – and it’s pretty obvious why. Their vast casino library incorporates 4,200 real money games that spread across thousands of slots and hundreds of table games. You can also take advantage of 150 free spins when you sign up today.

Gaming Variety: 4.7/5

National Casino works in tandem with over a hundred high-tech software providers to host 4,200 different casino games. You’ll find innovative provisions from PlayTech, Microgaming, Play’n GO, NetEnt, and many more.

We haven’t yet encountered an online casino with more to enjoy – when you sign up today, you can spin through thousands of high-quality slot reels and nearly 50 progressive jackpot reels.

Additionally, players looking for more than just slots will find a staggering number of live dealer versions of poker, blackjack, baccarat, and roulette alongside bingo, keno, and other specialty games.

The only market National Casino doesn’t touch is virtual sports betting.

Bonuses & Promos: 4.2/5

New players at National Casino will qualify for a 100% deposit match up to $100 or ¥ 12,000 and 100 free spins. Your second deposit will be credited with a 50% match up to $200 or ¥ 25,000, along with 50 additional free spins.

Over your first 2 deposits, you can take advantage of 150 free spins and a grand total of $300 in bonus cash. You’ll have to meet their 40x playthrough to cash out here, though.

Your 150 free spins can be used across their 3,000+ slot machines; we think their wagering requirements are steep for a listed $300 deposit match.

On the bright side, National Casino will give you 100 free spins on Journey Flirt (96.6% RTP) every Monday just for being registered with their site. Additionally, when you reload your casino wallet on Fridays, you’ll get a 50% match up to $250.

Banking Options: 4.1/5

National Casino accepts 9 fiat currencies and 3 forms of crypto.

Crypto fans can transact through Bitcoin, Litecoin, and Ethereum; while fiat bettors can wager through Visa/MasterCard, Discover, Skrill, Neteller, ecoPayz, Jeton, Interac, and Perfect Money here.

You’ll only need to deposit $20 across your first 2 deposits to qualify for your welcome bonus package and 150 free spins.

Additionally, we loved their lightning-quick fiat and crypto payout speeds. You can expect instantly processed crypto withdrawals and standard 48-hour fiat withdrawals here.

Mobile Compatibility: 4.8/5

National Casino’s mobile app manages to cram 4,200 games into one iOS and Android-friendly platform. Their app contains an organized layout and dedicated sections for each betting market they carry.

We had no problems depositing our crypto/fiat with one tap, placing wagers seamlessly, and initiating withdrawals while on-the-go.However, because their casino library is massive, older smartphones will suffer with slower loading speeds than we’d like to see.

3. Jackpot City – Best Online Casino in Japan for Progressive Jackpots


  • Great progressive jackpot slots selection
  • 300+ traditional slot machines
  • 4-tiered welcome bonus up to ¥ 160,000
  • Low betting limits
  • 15 banking options
  • Native mobile app for iOS + Android


  • 70x playthrough requirements
  • Some fiat payouts take up to 5 days

Jackpot City is the best casino online for big fish hunters. With over 100 progressive jackpot slots waiting for you here; you’d be hard-pressed to find larger payouts anywhere else.

Gaming Variety: 4/5

Jackpot City made our top-reviewed list for their vast selection of progressive jackpots. Big fish hunters looking for a huge payday should stop here. They host over 100 high-RTP jackpot slots that pay into the millions.

You’ll also find around 300 traditional slot machines to spin through when you feel like it. If you find yourself looking for something more engaging, you’ll have nearly 100 table games to keep you occupied.

You’ll have the opportunity to wager across 12 video poker variants, 17 games of online blackjack, 9 virtual roulette wheels, and 15 baccarat tables alongside 53 live dealer provisions.

Bonuses & Promos: 3.7/5

Players who sign up with Jackpot City today can score up to ¥ 160,000 in extra spending money. Their welcome bonus package is fairly straightforward – each of your first 4 deposits will receive a 100% match up to ¥ 40,000.

However, there’s a catch here. In order to cash out on your winnings, you’ll need to meet their 70x playthrough requirements. Of course, they’re banking on you hitting one of their numerous progressive jackpots and cashing out in one fell swoop.

Although walking away richer with Jackpot City is far from impossible, you should be prepared to spend a significant amount of time earning your bonus back.

Banking Options: 4/5

Jackpot City’s banking menu is packed with 15 secure payment methods.

You’ll be able to pad your casino wallet and cash out on your winnings through Visa, MasterCard, debit card, Interac, eCheck, MuchBetter, ecoPayz, Flexepin, ecoVoucher, bank transfer, and more.

We also appreciated their low deposit limits. However, you should know that some fiat payouts here are slow. Although e-wallet transactions are processed within 1 business day, you’ll have to wait a full 5 days for bank transfer, debit card, and Visa/MasterCard payouts.

Mobile Compatibility: 4.5/5

Jackpot City’s mobile app for iOS and Android devices comes across as very high-quality.

To their credit, they’ve made sure that every single game in their desktop library works flawlessly on (newer) smartphones. Players can enjoy full, on-the-go compatibility across their progressive jackpots, traditional slots, and table games.

However, because their app is very graphics-intensive, you might encounter some laggy loading speeds on older mobile devices.

4. Casumo – Best Online Casino in Japan for Roulette Games


  • Reasonable 30x playthrough
  • 1,992 slot machines
  • 100+ live casino provisions
  • Low deposit limits
  • 45+ game providers


  • No virtual sports betting options
  • No mobile app to speak of
  • Some fiat payouts are slow

Casumo is the best casino online for their massively generous welcome bonus. Over your first 3 deposits; you can get up to $1,800 in extra cash along with 100 free spins over your first 5 days with their site.

Gaming Variety: 3.9/5

Casumo hosts nearly 2,000 high-quality slot reels, and they bring 108 live casino games to the table for Japanese players.

In addition to their 1,992 high-RTP slots, players can enjoy 108 variants of live dealer poker, blackjack, baccarat, and roulette. If you’re looking for even more variety, you’ll be happy to know they carry 100 additional online table games and specialty provisions.

On their site, you’ll also find 12 video poker games, 28 versions of online blackjack, 19 baccarat tables, and 9 specialty dice games.

On top of that, Casumo carries a roulette wheel section that is unlike any other on our list. There are only 26 titles but it covers the classics and all types of roulette game you love.

Bonuses & Promos: 4.5/5

We really loved Casumo’s double-tiered welcome bonus package. Over your first 2 deposits, you’ll qualify for two separate deposit bonuses that can score you up to $1,000 in extra spending money.

Here’s how it works. Your first deposit of at least $15 will be matched with a 100% bonus up to $600. Your second deposit of $15 or more will each qualify for a 100% match up to $400.

In total, players can walk away with $1,000 in their casino wallets here, plus 300 free spins and $50 on Casumo Mahjong.

You can cash out on your bonus money and winnings derived from your free spins after meeting their reasonable 30x wagering requirements.

Banking Options: 3.7/5

Although Casumo hosts a limited banking menu; to their credit, they accept numerous e-wallets.

You’ll be able to add money to your casino wallet and withdraw your winnings through Visa/MasterCard, Interac, iDebit, MuchBetter, PaySafeCard, and ecoPayz.

We also liked their relatively low barriers to entry. You’ll be able to qualify for your welcome bonus with two individual deposits of $15 or more.

However, we’d like to see them improve some of their fiat payout speeds. As it stands, Visa/MasterCard and bank transfer payouts take a full 5 business days to process and deliver

If you’re looking to have your winnings in hand within 1 business day, we’d recommend going through one of Casumo’s accepted e-wallets to play here.

Mobile Compatibility: 3.8/5

Disappointingly enough, we didn’t find a native mobile app for Casumo’s platform. That said, their casino website is fully optimized for mobile usage; and we had no problem navigating through their library on smaller screens.

All of their slots work flawlessly on older smartphones.

However, before you make an account here, you should know that around 10 of their live dealer provisions aren’t compatible with mobile devices.

5. Spin Casino – Best Online Casino in Japan for Blackjack Players


  • 15 different versions of blackjack
  • 480 casino games
  • Around 400 high-RTP slot reels
  • 15 banking options
  • 3-tiered welcome bonus up to ¥100000


  • 70x listed playthrough
  • No free spins here
  • Slow fiat payouts

Spin Casino is the best online casino Japan has to offer for blackjack players. On their site, you’ll find 15 different blackjack games that include live dealer variants. You can also wager on over 40 live dealer games and nearly 400 high-RTP slots.

Gaming Variety: 3.8/5

Spin Casino hosts 15 different versions of blackjack through their website and mobile app. Skill gamers will be delighted to know that they can sit in with a live dealer for 5 of those blackjack variants.

Whenever you get tired of doing mental math, you’ll also have 378 high-RTP slots, a few progressive jackpots, and nearly 100 table games to keep you busy.

You’ll have the opportunity to place your bets on 47 live dealer versions of poker, baccarat, and blackjack. Additionally, you can scroll through 9 video poker variants, 16 baccarat tables, and 21 virtual roulette wheels.

Although we were disappointed to see them lack specialty games, they offer a very healthy selection of casino games otherwise.

Bonuses & Promos: 3.7/5

Ironically enough, you won’t find any free spins at Spin Casino. However, your first 3 deposits here can score you up to $1,000 or ¥100,000 in extra cash.

Here’s how it works – your first deposit with their site will qualify for a 100% match up to $400 or ¥40000. Your second and third deposits will each receive a 100% match up to $300 or ¥30000.

Although their bonus looks very tempting, you should know about their listed 70x playthrough before you decide to make an account here.

Banking Options: 4/5

Spin Casino accepts over 10 different payment methods – you’ll be able to pad your casino wallet using Visa/MasterCard, debit card, Interac, eCheck, PaySafeCard, iDebit, MuchBetter, NeoSurf, Flexepin, bank transfers, and ecoVoucher.

You’ll only need to put down $10 or ¥1,000 for each of your first 3 deposits to redeem their 100% welcome bonus package.

We were also happy to see them accept so many different e-wallets from players.

However, you should know that you’ll receive your winnings much faster when you choose to play through an e-wallet with Spin Casino.

Bank transfer payouts and debit card withdrawals take a full 5 days to post to your bank balance, while all e-wallet transactions take just 24 hours to process and deliver.

Mobile Compatibility: 4.5/5

Spin Casino’s mobile app is designed to accommodate iOS and Android devices.

You can enjoy the full scope of their casino library from the palm of your hand – we had no issues loading their slots, playing through blackjack games, and sitting in with a live dealer while on-the-move.

That said, their app is fairly graphics-intensive, which could result in perceivable lag on older smartphones.

We gave a higher ranking to sites that list the most versatile range of banking options alongside the fastest payout speeds.

Japanese players shouldn’t be limited to playing casino games from your computer. That’s why we prioritized mobile casino sites in this review. Additionally, sites that host a mobile casino app received a higher ranking from us.

Frequently Asked Questions (FAQs) About Japanese Casino Sites

Is Online Gambling Legal for Japanese Players?

Yes, it is. Online gambling laws permit Japanese players to enjoy popular online casino games and wager on their favorite sports through licensed Japanese casinos.

The Malta Gaming Authority licenses and regulates all the Japan casino sites we review. This means that you can enjoy gambling online without fear of getting into legal trouble.

Because the Japanese government is very lax when it comes to restricting online gambling; players can legally enjoy sports betting, online slots, live casino games, and other popular games (like poker and blackjack) from the comfort of home.

However, you will need to report your profits as taxable income to the Japanese government. Failing to report your online casino winnings as personal income can get you in lots of trouble.

Please check your local laws to make sure your chosen online casino is legal to use in your region.

Can I Play Live Dealer Games With Japanese Online Casinos?

Yes, you can. The best online casinos in Japan give players the opportunity to enjoy several variants of live dealer poker, blackjack, baccarat, and roulette.

Additionally, because many of the most popular casino games are available to play on mobile devices; you’ll find yourself sitting in for a hand of poker and blackjack no matter where you are.

Live dealer games bring the table to your screen. You’ll be faced with a real person dealing your hand, and you’ll enjoy the same betting odds that you’d find with any land based casino.

Are Online Casino Games Fair?

Yes, they are. Reputable online casinos in Japan offer provably fair online slot games, table games, live dealer provisions, and sports betting odds.

You can enjoy high-RTP (return-to-player) online slot games and view the “house edge” behind each table game before you put down real money.

That said, because all of our top-reviewed casino sites in Japan contain a valid operating license, they are regularly audited for fairness and volatility by the same authorities in charge of regulating in-person betting venues.

This means that the outcome of online slot games is randomized in your favor. Up to 98% of the money each machine takes from players is ultimately paid out in winnings. The same algorithm is applied to online table games and virtual sports bets.

All in all, no matter what you hear from disgruntled players on Reddit; licensed online casino sites in Japan aren’t rigged.

Can I Trust Online Casinos in Japan?

Contrary to popular belief, most casino sites in Japan are trustworthy. However, a few bad apples can spoil the bunch – for every licensed Japan online casino, there exists its unlicensed counterpart.

Players need to be alert and double-check their chosen site before signing up with any Japan online casinos.

Because unlicensed online casinos aren’t regulated; they don’t face any consequences for stealing your money, compromising your financial integrity, or selling your personal information to scrupulous third parties.

To ease your mind, you should know that all of our top-reviewed Japanese casinos are fully licensed and regulated. You can trust our top picks in the same way you’d trust your favorite in-person casino with your hard-earned money.

Will I Receive a Welcome Bonus From Japan Online Casinos?

Yes – all of our top-reviewed online casinos offer players the opportunity to redeem a generous welcome bonus.

Although welcome bonuses will vary depending on the casino site you make an account with, you can usually expect some combination of a deposit bonus, free spins, and a reload match that covers your next few deposits.

The best Japan online casinos list the lowest wagering requirements attached to the highest bonus match caps and the greatest number of free spins.

No matter which Japan casino you choose from this list; you can rest assured that you’re getting the best bang for your buck.

How Can I Pick the Best Online Casino for My Needs?

Choosing the best Japan online casino for you will boil down to your online gambling preferences. You’ll need to figure out what you’re mostly interested in ahead of time.

Japanese players who are mostly interested in finding the best online casino games and virtual sports betting options under one roof would find Lucky Niki or Casumo to be the perfect fit for them.

However, those looking for the best deposit bonus and largest number of free spins available would enjoy what National Casino, Spin Casino, and Jackpot City have to offer.
