Is online gambling legal in Japan?

Since September 2025 it is also unlawful to present or guide people to illegal gambling sites, though that rule has no penalty of its own. Ages: 20 for racing and for the casino, 19 for toto, 18 for pachinko; takarakuji has no legal minimum, but its official site asks for 20 for online membership. Race winnings are taxed as occasional income after a JPY 500,000 deduction, with only half of the result counted; takarakuji and toto prizes are tax-free. Real casinos are not open yet: the first, in Osaka, is targeted for around autumn 2030.

Gambling with crypto: Not offered by any lawful operator; gambling on an offshore crypto casino is a crime under the Penal Code however it is paid.

Online casino: Not available: online casino is a crime (land-based casino: 20). Sports betting: 20 (racing); 19 (toto). Lottery: No statutory minimum for takarakuji (official site asks for 20 for online membership); 19 for toto. 20 for racing and the casino, 19 for toto, 18 for pachinko; takarakuji has no statutory minimum, but its official site asks for 20 for online membership.

Takarakuji prizes and toto/BIG sports lottery prizes carry no income tax by statute. Horse and bicycle race payouts are occasional income: your year's total receipts minus the money directly spent to obtain them, minus a special deduction of JPY 500,000; only half of the balance is added to your other income and taxed in the ordinary way. For an ordinary racing fan, losing tickets are not deductible. If you buy continuously and aim at a profit over the year, the payouts count as miscellaneous income instead: losing tickets are then expenses, but there is no JPY 500,000 deduction and no one-half rule (Supreme Court, 10 March 2015). You declare the income yourself; the track, the JRA and the lotteries do not withhold. Residents are taxed on income from Japan or abroad, a non-resident only on Japan-source income; whether a non-resident's race payout counts as Japan-source income is not confirmed. No tax rule names casino winnings and no casino is open yet, so their treatment is not confirmed.

No operator holds an active online licence in Japan as of 13 Oct 2026.

No private operator holds a licence here, so a private site taking deposits from players in Japan is not licensed locally, whatever licence it shows from elsewhere.

Casino Regulatory Commission (casinos); ministries for public sports and lotteries's website

If a site isn't on the regulator's licensee register, ask the regulator before you play: an unlisted site is usually not licensed here (a register can lag behind a new licence). An unlicensed site is outside the regulator's supervision, so you cannot complain to the regulator about it.

  Only Use the Official Sites of the Public Bodies

  Lawful online betting is on the official sites of the statutory bodies: the JRA and local racing organisers, the bicycle, motorboat and auto racing organisers, the takarakuji official site and the toto official site, sometimes through sellers those bodies have contracted. Any site offering online slots, roulette or poker is an illegal online casino.

• ✓
  Check Who Is Behind the Site

  The official lottery sites are not all on a .go.jp address (the takarakuji site is takarakuji-official.jp and toto is toto-dream.com), so check that the site is the one a statutory body names as its own, not that it ends in .go.jp.

• ✓
  Expect Own-Name Bank Accounts or Cards

  The lawful sites take payment from your own name: JRA members bet from a designated bank account, takarakuji members need an own-name card and savings account, and toto takes cards, a named bank account or convenience-store payment. None of the sites read lists crypto-assets.

  Treat Affiliate Links, Social Posts and Ads for Online Casinos as Illegal Gambling

  Since 25 September 2025 it is unlawful to present illegal online gambling sites to people in Japan or to guide them there, and the National Police Agency lists links, recommendation-list sites and recruiting posts as prohibited. Police have arrested promoters and affiliates for aiding habitual gambling.

   1. Contact the Official Operator

   For a dispute over a lawful bet, start with the official operating body, such as the Japan Racing Association, which publishes an information desk. Land-based casino operators will be required to run a complaints window and keep complaint records for three years, but no casino is open yet.

   2. Consumer and Counselling Routes

   No gambling-specific complaint route to the Casino Regulatory Commission is described: its contact page offers a general opinion form and whistleblowing windows. The Consumer Hotline 188 connects to the local consumer centre, and the Basic Act directs the State and local governments to build counselling through mental health and welfare centres, consumer centres and the Japan Legal Support Center.

   3. Legal Action

   The regulator cannot order repayment to players, and no independent ADR provider is required. Players of illegal online casinos have no regulator to turn to; an offshore operator's own dispute body is a private promise by a foreign operator, not Japanese law.

• Myth

  Playing on an online casino is safe if the site is licensed in another country, such as Curaçao.
  Reality

  False. The National Police Agency says that playing from Japan is a crime even if the casino is lawful in its own country, and even for free versions and free bonus points. In 2025 police recorded 165 online gambling cases and 317 people; in the 158 home-access cases, 150 cases and 196 people were players. A player faces a fine of up to JPY 500,000, and a habitual player up to 3 years' imprisonment.

• Myth

  Paying through an agent or in cryptocurrency makes online gambling safe.
  Reality

  False. Payment agents have been arrested, including two in an Osaka police case in February 2025, and in May 2025 banks, crypto-asset exchangers and fund transfer providers were asked to take measures against payments to online casinos. The gambling itself stays a crime however it is paid for.

• Myth

  Gambling winnings are not taxed in Japan.
  Reality

  True only for official takarakuji lottery and toto/BIG sports lottery prizes, which are tax-free. Horse and bicycle race payouts are occasional income: winnings minus the money spent to win them minus a JPY 500,000 special deduction, with half of the balance taxed.

• Myth

  Japan blocks foreign casino sites, so a site you can open must be legal.
  Reality

  False. Japan has no power to order internet providers to block sites, and a government study group said on 22 July 2026 that blocking would need a law. A site that opens is not a lawful one: the police say online casino play from Japan is a crime.
