I would budget my trip day-by-day. If you are traveling by yourself, food should be about 2000 yen per day. 2000 yen is enough for a couple of restaurant meals each day (in less expensive or fast-food places).

Hotel rates very widely depending on the location and kind of room you like. As a ballpark figure, I would budget 5000 yen per day for hotels. That brings you up to about 7000 yen per day.

Since you'll have the JR pass, you won't have to worry about most transportation costs. But the trains don't go everywhere, you may have to take a trip or two by bus or even boat. Local bus fare runs from 200 yen to 500 yen, depending on the distance, highway buses (which you probably won't get a chance to use) run from 1500 yen to 5000 yen.

To be on the safe side, I would budget about 10,000 yen per day, and try to spend as little as possible. If you do it right, you should have enough money to visit a resort or two, and buy some gifts and souvenirs.

As a precaution, you should get travel insurance. If you are purchasing your airline tickets with a credit card, insurance may already be included as one of your card perks. If you can, it would be a good idea to get an airline credit card which is branded by the airline you intend to use for your trip. This will give you good coverage if you need to cancel your trip, lose your luggage, or have to deal with delays/canceled flights and other travel-related mishaps.
