Six numbers from 1 to 43. At 1 in 6,096,454 the jackpot is the most attainable of the four games here — and uniquely, the prize is not taxed at all.
You choose six distinct numbers between 1 and 43. The draw produces six main numbers plus one bonus number, which is used only to decide second place. The structure is nearly identical to Korea Lotto 6/45; the pool is 43 rather than 45.

The jackpot depends on sales and on how many people win it. If nobody matches all six, it carries over to the next draw, subject to a cap — it does not grow without limit.
The trade-off is visible here: the most attainable jackpot of the four is also the smallest. Odds and prize size generally move in opposite directions.
Japanese lottery winnings carry no income tax. The Act on Prize-Bearing Certificates provides that income tax is not levied on these prizes. Public revenue is taken at the point of sale rather than at the point of winning, so the prize is not taxed a second time.
That contrasts sharply with Korea's 22–33% above the threshold and with the US federal-plus-state treatment. The tax comparison page lays out all three.
The structure is nearly the same, with a pool of 43 instead of 45, which makes the jackpot slightly more attainable. The biggest difference is tax: Japanese winnings are not taxed.
No. Loto7 asks for seven numbers from 1 to 37 and has far longer jackpot odds. This site covers Loto6.
Rules, odds, and tax treatment differ from game to game. Reading two of these side by side is the fastest way to see how much.
