What can you tell me about JAPAN?

I am planning a trip to Japan, for about 70 days, and I was wondering about some of the follwing things:

What's the average price of food?

What's the general price of hotels per night?

What is the general price of renting small boats/ riding ferries?

You can give me this information in Yen or the US$ if you want. This information would really help! Thanks!
