Gambling Laws in Japan

Gambling in Japan is largely prohibited under the Penal Code, with exceptions for state-regulated activities such as horse racing, bicycle racing, motorboat racing, motorcycle racing, and lotteries.

Online gambling, including participation in foreign-based online casinos, is illegal for residents in Japan. Engaging in such activities can result in fines up to ¥500,000 or imprisonment for habitual gambling offenses.

In June 2025, Japan amended the Basic Act on Countermeasures Against Gambling Addiction to further restrict online gambling. The revised law prohibits the operation and promotion of online casinos, including advertising and disseminating information that leads to illegal online gambling.

Given these strict regulations, Japanese players are advised to refrain from participating in online gambling activities to avoid legal consequences.

Are There Any Taxes on Gambling Winnings in Japan?

Yes, gambling winnings in Japan are subject to taxation. The tax treatment varies depending on the type of gambling activity.

Public Sports Betting and Lotteries: Winnings from activities like horse racing, bicycle racing, and lotteries are generally considered "occasional income." For occasional income, half of the amount exceeding a ¥500,000 exemption is taxable. For example, if you win ¥1,000,000, the taxable amount would be ¥250,000 (¥1,000,000 - ¥500,000 = ¥500,000; 50% of ¥500,000 = ¥250,000). Gambling losses cannot be deducted from taxable income.

Online Gambling: Online gambling is illegal in Japan. Engaging in such activities can lead to legal consequences.

Integrated Resort (IR) Casinos: For winnings from licensed IR casinos, Japanese residents are taxed similarly to public gambling. Winnings exceeding a certain amount must be reported as occasional income on tax returns.

It's essential to report all taxable gambling winnings to the National Tax Agency during the annual tax filing period to avoid penalties.

Solutions to Common Problems in Japanese Online Casinos

Japanese players often face specific challenges when accessing international online casinos. Below is a table outlining these common issues and their respective solutions:

By understanding these challenges and implementing the suggested solutions, Japanese players can navigate the online casino landscape more effectively.

Player Protection and Responsible Gambling in Japan

Accessing and participating in online gambling activities from Japan is illegal under the Japanese Penal Code, even if the online casinos operate legally overseas. Engaging in such activities can lead to legal consequences, including fines and imprisonment.

International online casinos often implement various safety measures to protect players' data and promote responsible gambling. These measures include SSL encryption for secure transactions, data protection policies, and responsible gambling tools such as self-exclusion programs and deposit limits. However, these protections do not extend to players in Japan due to the illegality of online gambling within the country.

Responsible gambling practices promoted by international online casinos typically include:

• Self-exclusion programs allowing players to voluntarily ban themselves from gambling activities.
• Deposit limits to control the amount of money a player can deposit over a specified period.
• Reality checks providing regular reminders of the time spent gambling.
• Access to support organizations for individuals seeking help with gambling-related issues.

While these practices are beneficial, they are not applicable to residents of Japan due to the legal restrictions on online gambling. Engaging in online gambling from Japan can result in legal penalties, and players should be aware of the risks involved.
