Old rice store selling different kinds of rice. Some are grown using very little pesticides.
You can bring your own container.
The store is open everyday but most of the time the shutter is down. You can ring the doorbell on the left side of the door. It is probably best if you call the owner in advance to tell her your are coming: 03-3260-3032, as she is running the store on her own and is sometimes running errands.
