Next year's World Cup soccer finals, to be cohosted by South Korea and Japan, could generate economic benefits of up to 3.6 trillion yen if Japan wins the tournament, two private research institutes said Thursday.

The Dentsu Institute For Human Studies and the Institute For Social Engineering said they estimate economic effects of the event have been felt since the end of May 1996, when Japan won the right to host the tournament, and will continue until the event ends.

Based on data acquired through related local government and corporate questionnaires, as well as statistical tourism data, the institutions derived estimates of construction investment spending and of spending related to audience consumption of such things as drinks, food and souvenirs and related goods.
