Is Polymarket Legal in Japan? Available — Updated 2026

Quick Answer: Yes, Polymarket is available in Japan. Japanese users can access the platform without geo-restrictions, though Japan's financial regulations around crypto are among the most developed in the world.

Polymarket Status in Japan

✅ Available — Polymarket is accessible from Japan with no IP-based blocking as of March 2026.

Japan has one of the highest levels of trading activity on Polymarket in the Asia-Pacific region. The country's strong tech culture, combined with widespread crypto awareness following early Bitcoin adoption, has made Japanese users a significant presence on prediction market platforms.

Regulatory Context

Japan has one of the most comprehensive crypto regulatory frameworks globally, overseen by the Financial Services Agency (FSA):

• Crypto is legal and regulated — Japan was among the first countries to establish a legal framework for cryptocurrency through the Payment Services Act and the Financial Instruments and Exchange Act
• FSA oversight — The FSA regulates crypto exchanges and has licensed over 30 domestic platforms
• No prediction market ban — While Japan has strict gambling laws (only certain forms are legal, such as horse racing and pachinko), blockchain prediction markets have not been explicitly targeted
• No geo-blocking — Polymarket does not restrict Japanese IP addresses
• Stablecoin regulations — Japan enacted stablecoin regulations in 2023, which primarily affect issuers and exchanges rather than users

Gambling Law Considerations

Japan's gambling laws are strict — most forms of gambling are illegal under the Penal Code. However, prediction markets are generally viewed differently from traditional gambling because they serve an information discovery function. Polymarket has not been targeted by Japanese regulators, and the platform remains accessible. That said, users should be aware that Japanese authorities could reassess this position.

How to Get Started from Japan

1. Create your account — Set up your Polymarket wallet using our account creation guide.
2. Acquire USDC — Japanese users can buy crypto on licensed exchanges like bitFlyer, Coincheck, or bitbank, convert to USDC on an international platform, and transfer to Polymarket.
3. Trade — Start exploring and trading on prediction markets.

Funding Methods for Japanese Users

• Japanese bank transfer — Deposit JPY to bitFlyer, Coincheck, or GMO Coin, purchase crypto, then swap to USDC on a supporting platform
• Convenience store payment — Some Japanese exchanges accept konbini payments for deposits
• Quick deposit — Many Japanese exchanges offer instant JPY deposits via net banking
• Note on USDC — Most Japanese licensed exchanges may not directly offer USDC. You may need to buy ETH or BTC on a domestic exchange, transfer to an international exchange, swap to USDC, then send to Polymarket

Tax Considerations

Japan taxes cryptocurrency profits as "miscellaneous income," which is subject to progressive income tax rates ranging from 5% to 45% (plus 10% resident tax). This means total tax on crypto gains can reach up to 55% for high earners. Japanese users should maintain meticulous records of all Polymarket transactions and consult a tax accountant (zeirishi) for proper filing.
