dude everyone has good and bad experiences when they got to a foreign country...everbody!!! No matter what...I know it was probably bad what happened to you and i hope you weren't hurt with the knife and you had the fright of your life...and i know this sounds dumb but you should have made due with what little time you had in japan, cuz most of here on this forum would have loved the chance you had to just be able to go to japan, you should have seen the positive in your situation and just gone out to sightsee which i'm thinking isn't a lot of money.
I'm sorry you experienced something horrible while being in japan, and it probably makes you never want to go back, but like so many people who have gone there are a lot of good things about japan. Please don't be so negative. You should have let everything go and enjoyed the rest of your time, even if you were pissed off (sorry if i'm not supposed to say words like that)
