[Kanji_The_Wanderer]

^(Don't go off-topic please) If you are a tourist staying for a short while, which you are, I don't think you have anything to worry about. Just be polite like everybody has been saying. I am sure that plenty of people would like to help you out, as long as you seem interested, and involved with your surroundings. If you are friendly enough, you might meet someone who will be willing to help you out and give you tips once you get there!

Good luck, and have fun! (envious over here ) Make sure when you come back, you make a thread about it, and put up photos in the "Japan Trip Reports" section!
