A record ¥700 million will be paid out to the first-prize winner in the Year-End Jumbo Lottery if that person also purchased a block of tickets including the numbers immediately before and after the winning ticket, according to its organizer.

The organizer decided to raise the cash payout for the top prize to ¥500 million from ¥400 million, while keeping the payout for the two adjacent numbers at ¥100 million each.

The move is aimed at boosting Takarakuji sales amid intense competition from rivals such as the soccer lotteries.

A Jumbo Mini Lottery will also be launched, offering ¥70 million as the first prize — with a winning chance 10 times greater than a conventional Jumbo Lottery.

Tickets, at ¥300 each, for both the Year-End Jumbo and the Mini Jumbo lotteries will be offered for sale between Nov. 22 and Dec. 20.
