Sports Betting in Japan

What sports betting is legal in Japan

Japan treats gambling as illegal in principle, but a small set of products is authorized under special laws, partly as everyday entertainment and partly so the proceeds can flow back to public causes¹. For sports betting specifically, that means two families of products.

The first is the four public racing sports: horse racing, keirin (track cycling), boat racing and auto racing (motorcycle racing on paved ovals). These are pari-mutuel betting products run by public bodies, and they are the oldest and largest form of legal sports wagering in the country².

The second is the sports promotion lottery, better known as toto, which covers football and basketball. It is run under the Sports Promotion Voting Law and operated by the Japan Sports Council, with proceeds going to sport promotion⁹.

That is the full list. There is no legal way to bet on baseball in Japan, so NPB games are off the table, and there is no domestic sportsbook taking fixed-odds bets on soccer, tennis or anything else. If you see a private bookmaker or an offshore site offering those markets, it is operating outside what Japan allows, which we cover at the end of this page.

For the wider picture, including pachinko and casinos, see gambling in Japan.

Where you can bet on live racing

The four public racing sports each have their own venues, culture and betting style, but they share a pari-mutuel structure: the pool is divided among winning tickets, so payouts depend on how many people picked the same result.

Horse racing is split between central racing run by the Japan Racing Association (JRA) at ten racecourses including Tokyo, Nakayama, Kyoto and Hanshin, and local racing run by municipal governments at tracks such as Oi and Obihiro. We go into the full menu of wagers in Japanese horse racing bet types.

Boat racing (kyotei) is hydroplane racing, described by its own organizers as publicly managed sports betting². Six boats race around two marker buoys, and you can place bets for as little as JPY 100¹⁰.

Auto racing is motorcycle racing on a paved oval, run by municipal bodies in the same pari-mutuel style.

A few practical points that apply across all four sports:

• Bets are placed by filling in a marking card at a window or betting terminal, or through telephone and internet voting accounts, which now cover races held nationwide across all five racing products (central and local horse racing, keirin, boat racing and auto racing)¹¹.
• Payouts can be large, and the tax office asks anyone receiving public racing payouts to keep a note of the race date, venue and race, the amount received, and the amount wagered on the winning payout⁸.
• Each sport runs an entry restriction system based on self-declaration or family declaration, so people with a gambling problem can ask to be kept out of racecourses and off-course betting shops¹².

If you want to go deeper, we have separate pages on horse racing in Japan, boat racing, keirin and auto race.

The toto football and basketball lottery

The sports promotion lottery is sold under the toto brand, and it divides into four games: toto, BIG, WINNER and DUNK³. The core product, toto, asks you to predict the results of 13 designated football matches, mostly J.League fixtures¹³. For each match you pick a home win, draw or away win, and you can hedge by marking one match as a double (two outcomes) or triple (all three)¹⁴.

A single toto entry costs JPY 100 and covers all 13 matches in one pattern, which makes it the simplest starting point for a beginner¹⁵. The normal first prize is capped at JPY 100 million, and when a round ends with no full winner, prize money carries over and pushes the top prize higher¹⁶.

If 13 predictions sound like hard work, there is a shortcut: you can predict only the two or three matches you feel confident about, or just your favorite team's matches, and let the computer fill in the rest¹⁷.

Where to buy tickets

toto tickets are sold through several channels:

Online purchases of the sports lottery are permitted, since it is a sports promotion lottery issued by the Sports Council⁷. Our page on buying toto and BIG online walks through the process.

Collecting prizes

Where you collect depends on the amount. Prizes of JPY 100,000 or less per ticket can be paid at booths, credit unions or Seven-Eleven; anything over JPY 100,000 goes through a credit union; and prizes over JPY 500,000 require a credit union procedure, paid in cash after 12 business days or by bank transfer. Seven-Eleven pays out only up to JPY 15,000, and some booths cap payouts at JPY 10,000 or JPY 50,000 per ticket¹⁸.

BIG, toto, WINNER and DUNK: what each game covers

The four games share a family resemblance but suit different players.

toto is the prediction game described above, built around J.League and other designated football matches¹³.

BIG is the no-knowledge version of the same football fixtures. The computer randomly selects the match results for you, so you can join in without following the sport, and it aims at high prizes⁹. BIG and its related products are sold twice a week, and during the J.League off-season the operator has run BIG lotteries on overseas football, including year-end and New Year rounds¹⁹.

WINNER is the closest thing Japan has to a conventional sports bet. It offers single match prediction on designated fixtures and competition prediction on league and tournament outcomes, covering both football and basketball⁹. The designated events span a wide list: the football World Cup, Asian Cup, Super Cup, J1, J2, J3, the J playoff, Emperor's Cup, English League 1 and the German Bundesliga, plus the Basketball World Cup, B1, B2, the B League championship series, relegation playoffs and the B1/B2 promotion-relegation matches²⁰.

DUNK is the newest game, launched in 2026 as Japan's first sports lottery targeting basketball with no prediction required. The computer randomly selects basketball match results, so it works like BIG but for the B League²¹.

One thing to know before buying: the purchase methods differ between BIG, toto and DUNK on one side and WINNER on the other, so if you want WINNER together with the others, follow the separate WINNER purchase guide²³. A "Rakuraku Purchase" option for regular repeat buying is available for BIG, toto and DUNK²⁴.

We have dedicated pages for each game: toto, BIG and MEGA BIG, WINNER and DUNK.

Betting online: the official route and what is off-limits

Online wagering in Japan is allowed only on the four public racing sports, which are operated and self-regulated by the government or municipal bodies, and on lotteries issued by public bodies, including the sports promotion lottery⁷. That gives you two official online routes:

1. Racing voting accounts. Telephone and internet voting now covers every race held nationwide across central horse racing, local horse racing, keirin, boat racing and auto racing¹¹. For horse racing specifically, the JRA's internet voting lets overseas users buy tickets through the general PAT and A-PAT account types²⁵. We cover this in betting on Japanese horse racing online.

1. Sports lottery partner sites. The Yahoo!, Rakuten, SMBC and Docomo toto sites sell the sports lottery online²⁶.

Everything else online is off-limits. Online casinos are not legal for operators to deliver to Japan or for players to bet at⁷, and the consumer affairs agency states plainly that gambling at an online casino by connecting from within Japan is a crime even if the casino is legally operated overseas²⁷. Police have made clear they treat this strictly regardless of whether the site is licensed in its home country²⁸.

Betting with private bookmakers

This is the part to be direct about. Betting with a private bookmaker, whether a local one or an offshore sportsbook site, falls under the Penal Code gambling offense, which carries a fine of up to JPY 500,000 or a petty fine for a person who gambles²⁹. The same applies to offshore operators offering bets over the internet: anyone who purchases bets from such a source can be investigated by police and severely punished³⁰.

The racing authorities put it in equally plain terms for their own sport: betting on horse racing is authorized only through the methods the special law prescribes, and betting by any other method constitutes the crime of gambling³². So an offshore site offering odds on the Japan Cup is not a loophole; it is the same offense as any other private bet.

In practice, this means the offshore sportsbooks you may see advertised to Japanese users, covering soccer, baseball, basketball, esports and more³³, are not a legal option while you are in Japan. If you want that kind of action, the legal products above are what is available: racing bets from JPY 100 at the venues or through official voting accounts, and the toto family of football and basketball lotteries.
