A lot of cultures have the tradition of bringing a small, often edible, gift for coworkers when you return from a trip. Japan calls it omiyage (おみやげ) and takes it very seriously. So seriously that train stations and airports overflow with the precious, regionally specific and individually wrapped things.
Sogo's depachika has a lot of beautiful omiyage options — crackers, cookies, cakes that you can get wrapped.
These flaky, bite-sized pastries shaped like hearts will keep you going while shopping. The stand is at Sogo department store's depachika, the basement level food bazaar with bentos, cakes, omiyage, prepared foods, a liquor store and a grocery.
I got two of each mini heart — plain, sweet nuts and cheese — for less than $2.50.
