Gambling and Online Casino Regulations in Japan

Japan’s legal framework towards gambling is quite complex. Understanding its nuances can be daunting, especially for new players who wish to play popular casino games in Japan.

Japanese people can lawfully gamble in land-based establishments approved by the country. In such legal online casinos Japan government allows sports betting like horse racing & powerboats, and others. Nihonjin can also enjoy various lotteries or play known casino games in Japan, like pachinko.

It’s illegal for any Japanese to gamble on poker, slots & table games within the country. Despite the law uncertainty, you’ll get fined around 6,000 Yen or about 50 to 60 USD if caught.

Note: The only way for Japanese online casino players to gamble on poker or slots is in offshore-based online casinos, which is still unlawful.

How to Choose Safe Online Casinos in Japan?

  • Time: 5 minutes
  • Tools: PC or Mobile
  • Supply: Money

The importance of picking a reputable gambling site cannot be underestimated, as online casino regulations in Japan prohibit online gambling, you need to ensure a secure gaming experience by yourself. That's why below you'll find a brief guide written by our team of experts to help you understand how to select safe online casinos in Japan.

Online Casinos Licensing & Regulation
An important part of any legitimate site and the first criteria to look at is its regulators and who issues its licenses. Any international reputable site should be licensed by:

– Malta Gaming Authority;

– CuraΓ§ao;


– UK Gambling Commission.

These regulatory bodies issue licenses to online casinos if they meet their criteria. A regulator ensures an online gambling platform’s safety & security, as well as its fairness with check-ups, audits, or other tests.

Casinos Security Measures
Gambling sites need to have top-notch security measures that ensure players’ safety and their data confidentiality. An example of such is the encryption technologies like Secure Socket Layer, also known as SSL & TLS, or Transport Layer Security. Additionally, each site catering to Japanese online casino players should adhere to strict online gambling regulations in Japan to protect players’ privacy or game fairness. To make sure a gambling site provides fair games, you can check their independent auditors who guarantee gameplay fairness & safety.
Casino Game Selection
Having extensive game selections of slots, poker, baccarat, etc., is a must for any reputable gambling site. Japanese online casino players should look for sites that offer games produced by software developers, such as:

– Microgaming; – Playtech; – Evolution Gaming; – NetEnt.

Software providers like these ensure that all popular casino games in Japan offshore sites are of top quality with a unique theme, superb graphics, sounds, and gameplay.

Transaction Methods
Every trustworthy gambling site should provide its players with multiple transaction methods, from cards to e-wallets. Examples of such payment methods are Visa/MasterCard, ecoPayz, Neteller, Skrill, Paysafecard, Bank transfers, Interact, or cryptos like Litecoin & BTC. While many sites provide multiple transaction options, you should also check the processing time and transaction fees. These can be strictly individual from one online casino to another.
Customer Support Service
Another important criterion is whether the online casino has 24/7 active customer support. You should also check how many channels of communication you can contact them. Are they available only via email, or do they have phone and live chat support? These may often assist players with in-game issues, account troubles, or payment problems.

Top Online Casino Japan Bonuses & Promotions: Brief Overview

Below, we’ve explained everything you need to know about bonuses and promotions and their most common types:

  • Welcome Bonuses: These are offered to all players who’ve just registered in an online casino. They match up their first deposit up to 100% or more of a specific sum with set limits, plus some FS. These can be a deposit or no-deposit bonus, with the latter being smaller.
  • Reload Offers: These encourage existing players to deposit and play more. Like the welcome ones, they provide a match-up but with a lower than 50% and lower max match limits.
  • Cashback: Give a chance to gamblers to recover some of their losses. Usually, these are weekly and are up to 5-20% of a loss during a set period.

  • Max Cashout: Promotions allow players to win money without spending any, which is why maximum cashout exists. They prevent players from liquidating more than a set amount.
