Bentohs! A bentoh is a lunch box. They are inexpensive and usually delicious. Available at all convenience stores (konbini) and major train stations, the bentoh is the thrifty traveller's key to living cheaply in Japan. I found bentohs ranging from around ¥200 and up to ¥1000 for fancy-pants ones, like the wrapped up sake no osushi (salmon sushi) you see below. And as an aside, they all taste infinitely better than they look. Oishii!
