How much would I need to save roughly?, for accommodation, train transport around tokyo, and food, I want to eat alot of yummy japanese food is it expensive?
I'm not going to be doing lots of shopping, just eating food :) and maybe disneyland.

Answer:

Air fare: You need $1000-1500 if you are departing from US

Hotel: Usually, you need $120 per night if you want to stay at a hotel.
If you want to save money, you need to stay at a hostel which will cost $40-60 per night.
If you want to stay at a luxury hotel, you need $250-300 or more.

Food, transportation and others: You need $60-120 or so per day. If you want to enjoy shopping, you need more.

So you need $120 for hotel and $90 for others per day. If you want to stay in Japan for 2 weeks, the total cost will be $2940.
