food expense in Japan?

Hi Japan Guide,

My husband and I will spend 3 weeks in Japan. We are visiting Tokyo, Osaka, Hiroshima, Kyoto and Yokohama. How much money do you think we need to spend on food per day? We will try to be as frugal as possible. Thank you in advance.

The following page should give you a basic idea:

Hi Uji,

1 liter milk Yen 200
5 slices of bread (toast-style) 200 Yen
1,5 liters apple juice Yen 200
8 slcies of cheese Yen 250
1 tomato Yen 100
