Sorry for the double reply but just re-read your spoiler. Be warned about Japan. Not smoking is extremely hard despite you not being allowed to smoke in public. 20%+ of the population smoke.

The cigarettes are $6 for 20 Marlboro Red and you can smoke indoors whilst eating food in some places. The novelty of it means you will almost certainly smoke. I did as I couldn’t resist. Excessively. Last year. And I quit about 6 years ago. If you’ve recently quit it will be even harder for you. You will almost certainly smoke there. Even my non smoking partner smoked.
