The legal situation in Japan

Japan allows betting only on state-authorised activities such as horse racing and lotteries, and no regulator has authorised prediction markets. No specific regulator order against Polymarket was found, but Polymarket restricts Japan on its website. In May 2026 it appointed a Japan lead to seek approval, targeting 2030. In June 2026 the exchange Bitbank warned it may restrict accounts that send funds to prediction markets.

What are your options in Japan?

If Polymarket or local law restricts this country, the honest answer is: don't try to get around it. VPNs and third-party wallets break Polymarket's terms, can get funds frozen and may be illegal locally. Look for prediction markets or exchanges licensed by National Police Agency (gambling under the Penal Code); Financial Services Agency (FSA), and check back here: rules change.
