Fukuoka costs more than 20.4 billion yen to host the World Swimming Championships. This is due to additional expenses incurred due to the postponement of the event.

Fukuoka City has made progress in securing subsidies from the Japan Sports Agency and sponsorship funds from companies, but the city's burden has been approximately 10.7 billion yen, about three times more than originally estimated. On the other hand, the economic ripple effect on the city from hosting the tournament is about 10 billion yen less than previously estimated.
