I am leaving for Tokyo in about a week, and while yes I know it's not a good habit to have I'm a smoker. I read on a few different sites that smoking while walking isn't allowed, and so I was wondering is it okay to smoke anywhere on the street as long as your not walking and don't throw the cigarette butt on the ground (i.e. have portable ashtray)?
Also I read something about smoking areas on the streets, are these hard to find? And what about smoking in bars or restaurants?
Don't really want to be rude or get in trouble for smoking when I finally get to Tokyo, so I thought that the best policy is to just ask. :)
