Una Casita Beans Asagaya — Supermarket in Asagaya, Tokyo
Una Casita Beans Asagaya, inside the Beans Asagaya complex by Asagaya station, sells vegetables at greengrocer prices rather than supermarket ones, and the low ones are the off-spec produce.
What this place is
A supermarket in name, but the shelves lean greengrocer: vegetables and fruit take up most of the floor, with bread, bento boxes, sweets and seasonings alongside. Off-spec produce is where the prices drop, and the chives cost little enough to toss into any basket. Look for Mitsuya's baked Nagamochi among the Japanese sweets. A basket runs roughly ¥1,000–3,000.

Vegetables first, everything else after
This is a branch of Una Casita Beans, sitting inside the Beans Asagaya building in Asagaya, and what you notice walking in is how much of the floor is given over to vegetables and fruit. The sign says supermarket, but the arrangement reads greengrocer, with bread, bento boxes, sweets and seasonings filling in the rest.
Start with the produce. The vegetables are sold as off-spec, and the prices are the reason to come: chives cost little enough that they go into the basket without a thought, and the range stretches to less common vegetables you can browse through. Nothing about the quality drops with the grade, so a plain tomato or a bunch of greens behaves the way you want it to.
Among the sweets, Mitsuya's baked Nagamochi is the one to pick up first, a Japanese sweet that sits on the shelf beside the produce rather than in a separate department. The bread counter has an oregano long sausage that is worth adding to the same bag.
The building itself has a picture-book feel from the outside, which sets the tone before you are through the door. It is a small-format shop, so you move through it quickly, and the ¥1,000–3,000 you spend covers a full basket of vegetables with a sweet or a bread item on top.
The trade-off is range: this is a produce-led shop, so if you need a full weekly stock of meat, dairy and household goods in one pass, you will come up short. Come for the vegetables and the sweets, and treat the rest as a bonus.

Who is this for
This suits a traveler staying in or passing through Asagaya who wants to cook with vegetables and pay greengrocer prices rather than supermarket ones. It also works for anyone with a sweet tooth who wants a Japanese sweet like Mitsuya's baked Nagamochi alongside the shopping. And if you like browsing a produce section for less common vegetables, the range here rewards a slow pass.
If you need prepared bentos and a fuller run of daily groceries rather than produce, York Foods on Asagayakita is the practical stop.
The verdict
It is a produce-led shop rather than a full-range supermarket, so you will not cover a whole week's groceries here, but for cheap vegetables and a Japanese sweet on the way through Asagaya it does the job.
