Crypto Gambling in Japan: A Big Opportunity?

Key Takeaways

• Crypto gambling in Japan remains prohibited under the Penal Code, which bans most wagering despite government-run racing and lottery exceptions remaining in place.
• Crypto ownership is fully legal and regulated under the Payment Services Act, but using it for gambling remains prohibited regardless of where the platform operates.
• Japan’s pachinko industry survives through a three-step cash workaround that keeps the activity technically outside direct gambling prohibitions while functioning economically like wagering.
• Japan trails regional peers like the Philippines on online gaming access but leads on crypto regulation, creating a sharp gap between financial innovation and gambling policy.
• Reform is moving gradually, with the FSA reviewing crypto use in gaming, integrated resorts expanding, and a 2027 licensing round signalling measured but real regulatory momentum.

Japan is one of the most deeply rooted gaming cultures in Asia, yet it maintains one of the world’s most restrictive anti-gambling regimes. Crypto gambling in Japan sits at the intersection of these opposing forces.

The country has long embraced risk-driven entertainment through pachinko halls and public racing, but draws a hard legal line on most forms of betting. Cryptocurrency adds a new grey zone to this already complex environment.  

But with strong demand for gaming in Japan and growing crypto adoption, could Japan be the next best environment for crypto gambling?

Japan’s Gambling Laws

Japan’s gambling laws are famously strict. Under the country’s Penal Code, the laws prohibit wagering on games of chance, with a handful of exceptions: horse racing, bicycle racing, boat racing, motorcycle racing, and lotteries. Government bodies manage gambling activities, with revenue contributing to social welfare programs. Everything else, especially privately operated or online gambling, is generally illegal.

That hasn’t stopped demand, though. Japanese users wagered about ¥6.5 trillion (over $40 billion) on offshore betting sites in 2024, according to the Tokyo-based Council for Sports Ecosystem Promotion. While betting through overseas websites is also illegal, enforcement has historically focused on operators rather than players. In recent years, though, this has begun to change.

The legal framework leaves little ambiguity, with most forms of betting deemed illegal unless specifically authorized. Yet the Japanese online gambling market is expected to grow past $12.5 billion by 2033.

What Pachinko Has to Do With Gambling in Japan

Japan’s multi-billion dollar Pachinko market operates through a legal loophole.

Pachinko is classified and regulated as amusement, not gambling, but in practice, it functions very much like it. The “three-store system” is the legal workaround that keeps the Japanese arcade-style game quasi-legal.

In pachinko, players first exchange cash for metal balls. They sit at a machine and turn a handle to launch balls into a vertical cabinet filled with pins and moving parts. Some balls land in winning areas that release more balls, with successful hits releasing even more. Players can keep playing using these balls or stop at any time.

Unlike casinos, players don’t receive cash directly. They win prizes in the form of balls inside the pachinko parlor, which they exchange for special items. Those items are then sold to a separate, third-party vendor for cash.

Because the cash transaction happens outside the parlor, the game sidesteps direct gambling prohibitions while maintaining the economic reality of wagering. This structure is why pachinko is described as “quasi-gambling.”

The IR Laws and Their Limits

While online gaming activities remain prohibited in Japan, the government passed the Integrated Resort (IR) Implementation Law in 2018 to promote tourism and increase foreign investment. It marked a major shift by legalizing casino gambling, but only within tightly controlled, land-based resorts.

The law allows up to three IRs combining casinos with hotels, conference centers, and entertainment. It establishes the Casino Regulatory Commission to oversee operator licenses, game standards, and background checks. Domestic residents are permitted to visit but face restrictions. A maximum of 3 visits every 7 days and a ¥6,000 entrance fee (approximately $38).

As of now, Osaka is the sole approved IR location, with a large-scale casino resort targeting a 2030 launch. A second round of applications for one of the remaining two licenses will open in 2027.

Importantly, this legalization does not extend to online gambling. Even under the IR framework, online casinos remain prohibited, as the law only legalizes gambling activities conducted in land-based casino facilities located within an IR area.

Where Cryptocurrency Sits in Japanese Law

In Japan, cryptocurrency is fully legal and regulated primarily under the Payment Services Act (PSA), which is overseen by the Financial Services Agency (FSA). However, that was not always the case. Prior to 2016, crypto remained largely unregulated, though authorities maintained a largely progressive stance to avoid stifling innovation in the emerging industry. 

Japan later amended its PSA law to establish cryptocurrencies such as Bitcoin as a legal payment method. Further updates to both the PSA and the Financial Instruments and Exchange Act (FIEA), the country’s two main crypto-facing legislative acts, came into effect in 2020.

Under this framework, cryptocurrencies and utility tokens like Bitcoin and Ether are classified as “Crypto Assets”. Stablecoins such as USDT and USDC fall under “Electronic Payment Instruments” (“EPIs”). 

Japan’s regulatory system also imposes strict requirements on Crypto Asset Exchange Services (“CAES”), which must register with the FSA and comply with requirements on custody, security, consumer protection, and AML/KYC.

Together, these measures have created a strong legal foundation for crypto in Japan, even as its use cases, like gambling, remain subject to separate scrutiny.

The Legal Line Between Crypto Ownership and Crypto Gambling

There’s a clear distinction when it comes to crypto usage in Japan. While owning and trading cryptocurrency is completely legal, using it for gambling is absolutely not. 

Adoption, however, remains strong, with an estimated 4% of Japan’s total population currently owning crypto. Projections even suggest that the number of crypto users in Japan will continue to grow, reaching 18.69 million in the near future. 

According to Chainalysis’ 2025 report, Japan recorded the “strongest growth” among APAC’s top five markets, with a 120% increase in on-chain value received in the 12 months leading up to June 2025.

Despite this widespread adoption, Japan defines the legal boundary, with the use of crypto barred from gambling purposes. So, under Japan’s iGaming regulation, currency is not the issue; the activity is.

As a result, crypto gambling falls into the same prohibited category as traditional online betting. Even when platforms operate offshore and rely on crypto transactions, the underlying activity remains illegal under Japanese law.

Japan vs. the Region: A Regulatory Snapshot

Within the broader Asian gambling market, Japan stands out as conservative on online betting but progressive on crypto regulation. Here’s how it compares to its regional peers.

When it comes to iGaming regulation, Japan lags behind more permissive jurisdictions like the Philippines, where players can access licensed crypto casinos, especially in online and crypto-integrated gaming models.

Could Japan Legalize Online Gambling or Crypto Casinos?

In recent years, policymakers have shown growing interest in crypto and Web3 innovation as well as gambling.

When it comes to gambling, the country has been considering casino legalization for decades and is working on expanding the development of integrated resorts. But as far as online casinos go, there is no concrete legislative pathway yet. In fact, Japan is making moves toward blocking illegal online casinos, with a revised gambling addiction law even prohibiting promotion for offshore platforms targeting Japanese citizens. 

There have also been plans to lift restrictions on sports betting, but these attempts were recently thwarted when Japanese lawmakers unanimously opposed the move, warning that it could threaten sports integrity.

As for crypto, over a year ago, the FSA announced its intention to amend legislation governing crypto use in gaming as part of the nation’s effort to modernize its regulatory framework. Separately, the Web3 project team of Japan’s ruling Liberal Democratic Party (LDP) has flagged the current tax structure as non-optimized for startups.

Notably, Japan regulation tends to move cautiously, so any shift will likely be incremental and tightly controlled.

Are There Crypto Gambling Risks for Players in Japan

Consumer appetite for crypto payments is on the rise, outpacing regulatory enforcement. When using crypto casinos, players face risks including regulatory uncertainty, security threats like phishing and hacking, and price volatility.

Players who access offshore crypto gambling platforms operate in a grey area. While enforcement against individuals has historically been limited, the activity remains illegal under Japanese law. 

There are also practical risks, such as a lack of consumer protection, challenges in dispute resolution, and potential exposure to unregulated operators. The decentralized, borderless, and pseudonymous nature of crypto does not change the legality of gambling.

Final Word

Japan presents a clear contradiction. It has one of the most mature crypto ecosystems in Asia, backed by clear regulation and institutional oversight. At the same time, it maintains a firm stance against gambling, especially online gambling, while allowing for a few government-authorized exceptions. The gap between those two realities is where both the opportunity for crypto gambling and the uncertainty lie.
