Kawazu

This blink-and-you'll-miss-it grocery store is famous for an unusual dish: fruit sandwiches (フルーツサンド furuutsu sando) prepared by placing generous portions of sliced seasonal fruit -- strawberries, grapes, persimmons! -- between slices of white bread and sealing them in with copious amounts of whipped cream. From ¥500 each.

This mid-range hot spring ryokan has seen better days, but it has one unrivalled draw: a series of no less than 6 outdoor baths at the base of the thunderous 30-meter Odaru waterfall, and you can even go for a (freezing) dip in the waterfall itself! The outdoor pools are shared, so bring a swimsuit. There are also indoor baths and a large swimming pool.
