It is the only food store I have found that has any vegetarian (mostly vegan) food. It has a wide selection, including lots of vegan or vegetarian frozen "meat" and gyoza, and some other types of health food, vitamins, etc.
To find it, go out Nonami (Sakuradori, "Red" line) exit no.2. Don't cross any streets. Walk North-East (face so that the UFJ Bank across the street is to your left) up Highway 59 for about 10 minutes or so. Karuna will be on your right. The sign has colourful circles on it.Pros: A large selection of vegetarian food, Almost everything in the shop is vegetar
Cons: A bit far from downtown, a little expensive
