QUESTION: What to bring to Japan to live.
Bring lots of deodorants.It's hot but Japanese deodorants are a joke, an expensive joke.
You'll need a pair of unused atheltic shoes for use only indoors at most health clubs. You can't just walk into a Japanese gym with your street sneakers and cut-offs. You gotta have DELEGATED new exercise shoes and preferably delegated exercise clothing too. If you're like me, finding size 12 EEE gym shoes is gonna be a pain (Cost-co Japan and Sports Authority here have them sometimes).
Once I needed deck shoes for yacht party on the Trump Princess. US Embassy very begrudgingly got them for me from the Navy Exchange on Yokosuka only after calling my US Senator a couple of times. The same problem can happen for some US medications not approved in Japan.
