Answer:

About $1400 for a plane ticket from the USA
About $2000 for living expenses for 3 months (plenty of 60000 yen (about $650) per month apartments/guest houses available) + food
Travel costs will be largely dependent on what you do. But another $2000 should be enough for a comfortable time.

This is all a rough estimate but it is about what I am paying.
