Thanks for all the help!

As far a flights go I've looked on several travel sites and the flights seem to range fro $800-$1,300 (USD) one way, does this seem about right?

On guides I'm not sure on how easy it is for an English speaking person who know very little Japanese to get by there. Also in South Korea, according to their government run travel website, they offer guides free of charge who will help you get around the country with ease. I wasn't aware if Japan did the same or if it just a goo thing to have a friend with you.

On Hotels, cabs and overall costs, are you saying try to avoid tourist geared hotel as they are way more expensive? What exactly is a youth hotel? and How would a visitor use public transportation?

On being big, that's good to know someone similar was there, I didn't expect them to be rude though. Just curious.

Again thanks for all the great help!
