Gambling laws in Japan - iGaming Agency

Gambling in Japan is undergoing its most significant transformation since the post-war era. Driven by the 2018 Integrated Resorts (IR) Implementation Act and the recently enforced Basic Act on Countermeasures Against Gambling Addiction (Amended 2025), Japan is moving toward a highly interventionist model focused on tourism growth and digital safety. This analysis provides a detailed overview of the legal status, taxation, player protection, and future trends of the Japanese gambling market, which remains a multi-billion-dollar sector through its unique amusement and state-regulated sports industries.

Is gambling legal in Japan?

No, gambling is strictly prohibited under Chapter 23 of the Japanese Penal Code. However, legality is strictly contingent upon specific statutory exceptions granted for state-authorized “public sports,” lotteries, and the newly established framework for licensed Integrated Resorts (IR).

Short answer to legal status

While the Penal Code criminalizes most forms of wagering, several primary forms of gambling are legal under special laws:

casinos – legal only within authorized “Integrated Resorts”; the first facility is scheduled to open in Osaka in 2030,
sports betting – legal only for four public sports and the Toto football pools,
online gambling – Japan does not license private online casinos. Participation in offshore online gambling may constitute a violation of the Penal Code, although enforcement has historically focused more heavily on operators and promoters than individual players.

Legal status of gambling in Japan

The legal status of gambling is defined by a centralized system that prohibits general gambling while creating specific “safe harbors” for activities deemed beneficial to the public interest or tourism.

penal code (Articles 185 & 186) – prohibits general gambling and the operation of gambling venues for profit, with penalties including fines and imprisonment,
jurisdiction – unlike the UK’s point-of-consumption licensing, Japan operates a prohibition-by-default model for digital gambling. Japan does not currently provide a licensing framework for private online casinos targeting domestic residents,
regulatory shift – since late 2025, the government has adopted a proactive approach to blocking offshore sites and removing promotional content from social media platforms.

Key gambling laws and regulations

Penal Code (1907) – the foundational law criminalizing unauthorized gambling,
IR Implementation Act (2018) – legalizes the development of up to three casino-resort complexes,
Basic Act on Countermeasures Against Gambling Addiction – the amended framework significantly restricts advertising and promotional activities related to illegal online gambling services, including certain forms of celebrity endorsement,
Amusement Business Act – regulates Pachinko parlors as amusement venues, exempting them from the Penal Code’s gambling definitions.

Regulatory authority

The Japan Casino Regulatory Commission (JCRC) is the independent body responsible for licensing and oversight of the casino industry. Public sports are regulated by their respective ministries.

Casino gambling laws

integrated resorts (IR) – only three locations can be authorized nationwide. Currently, MGM Osaka is the only approved project,
application window – a second round for the remaining two licenses is scheduled to open from May 6, 2027, to November 5, 2027,
resident restrictions – to prevent addiction, Japanese residents face a 6,000 JPY entry fee and visit limits (3 times per 7 days; 10 times per 28 days),
tourist access – current policy indicates that casino winnings paid to non-resident visitors are not subject to standard Japanese income tax withholding, supporting tourism objectives.

Sports betting laws

public sports (Kōei Kyōgi) – betting is legal only on horse, bicycle, powerboat, and motorcycle racing,
online betting – legally permitted only through official state-run platforms for the public sports,
prohibited sports – domestic sports betting outside the designated public sports framework remains generally prohibited under current law.

Lottery and other gambling activities

state lotteries (Takarakuji) – officially authorized and operated by local governments to fund public projects,
pachinko & pachislot – these operate via a “Three-Store System” loophole:

Players win “special prizes” (tokens) at the parlor.
Tokens are exchanged for cash at a separate, independent exchange booth nearby.
Because the parlor does not provide cash directly, it is legally classified as “amusement”.

Legal gambling age and player protection

minimum age – the legal age for public sports, lotteries, and upcoming casinos is 20 years old. For Pachinko, the age is 18,
2025 protections – authorities have strengthened cooperation with ISPs and digital platforms to facilitate the removal or blocking of links to illegal online gambling services,
addiction support – IR operators must provide counseling services and implement self-exclusion programs for residents.

Are winnings taxed?

residents – gambling winnings are generally treated as “temporary income” under Japanese tax law. A 500,000 JPY special deduction applies, but taxable amounts depend on overall income and deductible expenses,
tourists – casino winnings paid to non-resident visitors are generally not subject to Japanese income tax withholding, consistent with current tourism policy,
operators – IR operators are subject to a 30% tax on Gross Gaming Revenue (GGR).

Penalties for illegal gambling

operators – running unauthorized gambling venues can lead to up to 5 years in prison,
players – participation in unauthorized gambling activities may result in fines or imprisonment of up to three years under the Penal Code,
digital enforcement – as of late 2025, authorities treat online casino promotion as “illegal information,” allowing for faster site blocking.

Legal status of gambling advertising

2025 ad ban – the amended framework significantly restricts advertising and promotion of illegal online gambling services, including digital and social media channels,
celebrity endorsements – the amended framework restricts the use of celebrity endorsements in connection with illegal gambling promotion, particularly where youth audiences may be affected,
mandatory warnings – all permitted gambling ads must include prominent warnings about addiction.

Future of gambling laws in Japan

The next few years will focus on the opening of the first physical casinos and the digital cleanup:

2027 application round – selection of the final two locations for integrated resorts,
AI integration – regulatory discussions include the potential use of advanced monitoring technologies to identify high-risk gambling behavior within IR facilities.
2030 Launch – the first integrated resort in Osaka is currently scheduled to open around 2030, subject to construction timelines and regulatory approvals.
