The last time it hosted the Olympics, in 1964, Tokyo earned $1 million from an official Olympics-branded cigarette.

"I want to do this," Masuzoe said on a Fuji TV show this week when asked about the possibility of introducing stricter curbs. "If I get cooperation from the Tokyo Assembly, we can pass an ordinance."
