How much should I save for a 2 and a half week holiday in Japan?

Question:

My flights from Australia to Japan RETURN was only $499 because of a huge sale.
I'm planning on staying at a backpackers and mostly staying in Tokyo but I also will see some of the country.
I will see the Zoo's and may see Disney Land and buy cheap stuff and cheap food. Do you think $2500 would be enough?

Answer:

Hotel: Usually, you need $100 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 $30-50 per night.
If you want to stay at a luxury hotel, you need $200-300 or more.

Food, transportation and others: You need $50-100 or so per day. If you want to enjoy shopping, you need more.

So you need $100 for hotel and $75 for others per day. If you want to stay in Japan for 2 weeks, the total cost will be $2450.
