Loto 7 (Japan) in a nutshell
Loto 7 is Japan’s biggest number-selection lottery, sold under the national Takarakuji brand. A ticket costs ¥300 and the draw is held every Friday. Players choose seven numbers from 1 to 37; each draw produces seven main numbers and two bonus numbers that only count for the second and sixth prizes. The first prize is up to ¥700 million, or up to ¥1.2 billion with a carry-over, and lottery prizes in Japan are tax-free. You can buy up to five lines per slip, or use Quick Pick.
How to play Loto 7 (Japan)
- Choose seven different numbers from 1–37, or let a Quick Pick choose them for you.
- Wait for the draw and compare your line with the winning numbers; the order does not matter.
- The top prize needs all seven main numbers; smaller combinations win lower prizes set by the operator.
