Japan has several lottery games; the most popular one is Bingo 5. The draw for this takes place just once a week, on Wednesdays at 8 pm. The player selects a set of numbers from a more extensive range, as for most lotteries around the world.
Tickets are on sale until a short time before the draw takes place, then sales restart after the draw is completed. These can be purchased via retailers and online.
The results can be seen on television, but they are also published online shortly after the draw has been verified. A player who believes they have won a prize can have their ticket checked at the retailer if they bought it in person, but if they purchased it online, then the checking is automatic.
Smaller prizes are paid via the retailer or directly online, but a claim has to be made for a larger prize.
