Perhaps I'm foolhardy but at this stage I'm 99% certain I'm going there in April for a week or so before I go to a different part of Asia (likely Vietnam). Obviously I speak no Japanese (might be bit of a problem ) and a completely different culture to what I'm used to. Plus there is enough cheap flights there I can get a bargin. At this stage I'm going Tokoyo, Osaka, and down south to Hiroshima and see the site where the Atomic Bomb got dropped (my grandfather on my mum's side was sent there in WWII three days after the bomb to help out in the clean up and walked around in his sailor suit and a pair of thongs )
Anyway I know about the country or customs or heck language, so some advice or have I bitten off more then I can chew?
