I’m not implying causation here but I was surprised to see such a big smoking culture when I visited Japan. A lot of establishments have designated smoking rooms that are kinda cool and chic, with sliding glass doors and a motley crowd — young hipster types, business people, casuals. And the farther you are from an urban center people straight up smoke wherever. Watched the owner of a cafe make me eggs while casually enjoying a cigarette. I didn’t perceive as big a stigma and it kinda made me miss smoking.
