Very good store, with lots of selection for packaged and fresh food. They also have a very good selection of fresh ready to eat food, hot and cold, like 600yen for a tray of sashimi, or 500yen for a package of tempura meat with rice. We actually ate supermarket meals fairly often while visiting Japan, since the food was very good and very cheap. The only negative here is that they accept cash only.
