Smoke
It is recently easy to find smoke-free cafés in Tokyo, because such smoke-free cafes increase in these days. Local governments made the regulations to prohibit to smoke on the road, so a lot of smokers try to find some spots such as smoke-free cafés. Therefore many cafes made a smoking sub-room or a smoking corner separated by glass panels. If you would like to find smoke-free cafes, please ask a staff at the cafes, perhaps he will answer YES.
