The flight would probably be the biggest part of the cost.
We are a company who help people to get cheap hotel booking, so if you are on a budget, we could get you a hotel room for 2 for as low as USD90 in Tokyo area, or even less if you are not asking for 5-star service.
All hotels in Japan are pretty clean, so nothing to worry about the quality.
As for food, it really depends what you eat, general japanese meal for everyday life cost around USD6 to USD10, dinner would cost a bit more of coz. If you are going for expensive beef, etc., that would be expensive (USD50 per person depends how much u eat).
If you would like to have a tourguide, we could also get you a tourguide as well, to guide you through place that might be difficult for foreigners.
