Tokyo Gov. Yoichi Masuzoe on Tuesday cautiously welcomed the International Olympic Committee's decision to open up the event to new sports but spoke of anxiety over the costs of providing them in 2020.
Masuzoe said he will have to discuss the possible inclusion of new disciplines with the Tokyo 2020 Organizing Committee.
In Monaco, the IOC on Monday approved a new framework, scrapping the current cap of 28 sports at the Summer Games and allowing the addition of new pursuits, which could enable the return of baseball and softball, and karate.
Referring to baseball's chances, Masuzoe said Tokyo must first gain international support, as the Japanese professional baseball and U.S. major leagues will be in season during the Olympics.
