OK Store Kamiooka

Almost always busy but the prices are quite reasonable and they also have some rate items (the brown rice crackers being my favorite) . You have to be careful with food prices as the price displayed in the bigger font is for members and only when paying with cash. Non-members and/or credit card holders will pay slightly more. The displayed prices are not tax inclusive, which is a practice I don't approve of.

Prices were a bit more expensive than other groceries in the area, but more choices and one of the few places that accepts credit cards.

Prepared foods are high quality and cheap. Produce is more expensive than the other stores in the area. Other items vary, although a lot of the staples that I buy (e.g. pasta sauce) are slightly cheaper, but you can't rely on that. You need to compare prices if you want to be sure. It's probably the largest supermarket in the neighbourhood, and therefore has the best selection.

This superstore has a very large selection and reasonably low prices. Some of it wasn't the cheapest I have found, but everything was priced below average for Tokyo. Selection highly oriented towards the Japanese market, so selection was poor in certain areas (cheese for example). Almost nothing in the way of English signage or availability.

Huge selection for a Japanese supermarket. Deli section is decent. Prices are... Ok. With some things being much cheaper than elsewhere, but some being the same or more expensive, so you do have to pay attention.
