Every Japan game on this site, ranked by top-prize odds, with the tax rules and the regulator. All odds derived from the published rules.
| Game | Top-prize odds | Any-prize odds | Ticket | Cost per unit of jackpot chance |
|---|---|---|---|---|
| Numbers 3 | 1 in 1,000 | — | ¥200 | 200,000 JPY |
| Numbers 4 | 1 in 10,000 | — | ¥200 | 2,000,000 JPY |
| Loto 6 | 1 in 6,096,454 | 1 in 36.81 | ¥200 | 1,219,290,800 JPY |
| Loto 7 | 1 in 10,295,472 | 1 in 26.13 | ¥300 | 3,088,641,600 JPY |
| Jumbo Takarakuji | 1 in 20,000,000 | — | ¥300 | 6,000,000,000 JPY |
Shorter odds are not automatically better value — shorter-odds games pay smaller top prizes. Cost per unit of chance (price × odds) is the cleanest single comparison.
Takarakuji prizes are exempt from income tax and residence tax under Japan's Lottery Ticket Act — winnings need not be reported, whatever the size. Sharing a prize can trigger gift tax for the recipient on amounts above the annual JPY 1.1 million gift allowance, and foreign winners should check liability in their home country.
Winners are not publicly identified; claims through banks are confidential.
