Japan may not bid to stage the 2022 World Cup in the event Qatar is stripped of the hosting rights and a revote takes place, Japan Football Association president Kuniya Daini said on Monday.

"We've got the Olympics, and we have to think about our overall domestic situation," Daini said.

Domenico Scala, the independent chairman of FIFA's audit and compliance committee, has told Swiss newspaper SonntagsZeitung that if evidence emerges that Russia and Qatar bought votes in their bids to host respectively the 2018 and 2022 World Cup, they could lose their rights to stage the tournament.

Japan, South Korea, Australia and the United States ran against Qatar in the race for the 2022 hosting rights.

Japan, though, already has its hands full with the 2019 Rugby World Cup and the 2020 Olympics in Tokyo, and Daini said it could be difficult to host another international sporting event the size of a FIFA World Cup.

Plans for Tokyo's new National Stadium, to be the centerpiece of both the Rugby World Cup and the Summer Games, are under serious review. The blueprint for the Olympics — now anything but compact, which Tokyo sold itself on during the bid — has come under heavy scrutiny as part of cost-cutting measures.

But Japan could throw up its hand to host the 2023 Women's World Cup.
