New Tokyo Gov. Yoichi Masuzoe said Wednesday he will work hard to make the capital the best city in the world, while noting that it's up to the central government whether to bring the nation's nuclear reactors back online.

"In order to make Tokyo the best in the world . . . above all, we have to make various preparations for the 2020 Olympics and Paralympics, not only enhancing the infrastructure," 65-year-old Masuzoe said during his inaugural news conference at the metropolitan government building in Shinjuku Ward.

Masuzoe, who took office Tuesday after winning Sunday's election, reiterated that he will aim to hold "the best ever" Olympics and will go all out to make sure that the athletes and other visitors leave Japan saying the 2020 Games were the greatest they've ever seen.
