Yoshiro Mori, president of the Tokyo Olympics organizing committee, is asking the new Tokyo Metropolitan Assembly to cooperate in tackling issues related to hosting the games.

"As one who was involved in politics, I had anticipated this (election) outcome, but I never imagined it to be this much," Mori, a former prime minister, said during a committee meeting in Tokyo on Monday, a day after Gov. Yuriko Koike's new party handed the ruling Liberal Democratic Party a resounding defeat.

Koike's Tomin First no Kai (Tokyoites First) and allies secured a majority in the metropolitan assembly.
