A round-the-clock branch on Kamiuma
This is a branch of the Maruetsu chain, on Kamiuma in Sangenjaya, a short walk from Sangen-jaya station. What you notice first is how compact it is: a neighbourhood supermarket sized for a daily errand rather than a weekly haul, with fresh food, prepared foods and daily necessities packed into a small floor.
The prepared food counter is where a quick dinner gets sorted. That section is the one worth heading for when you are tired and hungry, and in the evening sashimi and other items are marked down, which makes a late stop pay off. An Aeon ATM sits at the entrance, handy if you need cash.
The store runs 24 hours, which is the whole point of the place. Come in late from work, or after realizing you forgot something, and it is still open. The building is old and the prices run a bit high for what is a compact shop.
Checkout with AEON Pay has caused trouble when the app and the register do not line up.
For all that, it does the everyday job: a small floor, a full range of fresh and prepared food, and a door that never closes. If your need is a late meal or a forgotten item, the timing is the reason to choose it.
