Also worth mentioning, if you go to Japan they don't expect foreigners to have the same body shape, height or width wise.
When I went over last, as a tourist so it will be different from living and working, but still perhaps relevant, I was a UK size 14 (5'7 and about 155lbs)
By Japan standards this would be huge, yet I didn't hear a single comment or see anyone stare and even found some clothes to fit (an XL woman's long sleeve blouse and size M souvenir type t-shirts)
I tried on a top in a boutique in shibuya and it was only a tiny bit too small (my boobs got squished) and the shop assistant was polite and helpful and seemed a little shocked when I said the top was too small (probably just being polite but still)

So don't worry too much!
