Japan lottery number generators
Japan runs 5 lottery games covered on this site: Loto 7, Loto 6, Mini Loto, Numbers 3 and Numbers 4. Between them you'll find a mix of number-matrix draws and pick-your-own-digits draws, operated by Mizuho Bank.
Pick any game below for a generator scoped to that draw, its exact number ranges, and a plain-English breakdown of how it works. Every set of numbers is biased using your Western star sign and your Chinese zodiac year — entertainment only, never a strategy for beating the actual odds.
