Japanese supermarkets (supa) are a food lover's paradise — the quality, variety, and presentation of Japanese grocery stores exceeds almost anything comparable in the Western world. Here's what to look for and how to navigate them.
The Major Chains
Aeon/Jusco: Japan's largest supermarket chain — nationwide, everything from produce to appliances in larger stores. Ito-Yokado (7i Holdings): High quality, strong prepared foods section. Maruetsu, Life, Seiyu: Urban neighborhood chains in Tokyo. Fresco/Fresco Midi (Kyoto): Kyoto's main regional chain — good for Kyoto-specific vegetables (Kyoto yasai) and traditional ingredients. Hankyu Oasis (Osaka): Premium supermarket in Osaka's upscale districts.
The Prepared Foods Section
The hot/cold prepared food area (sozai) is the heart of a Japanese supermarket: Karaage: Freshly fried chicken, still hot. Best bought and eaten immediately. Tempura: Individual pieces of vegetable and seafood tempura. Sashimi: Cut and packaged by in-store fishmongers — quality is noticeably better than Western supermarket sashimi. Bentō: Full lunch boxes, fresh daily, marked down 20–30% after 18:00–19:00 (look for "30% off" discount stickers — a ritual for budget Tokyo living). Onigiri: Often made in-store rather than factory-produced at quality supermarkets.
What to Buy
Seasonal vegetables: Japanese supermarkets are meticulously seasonal — lotus root (autumn), bamboo shoots (spring), kabocha pumpkin (autumn). Tofu varieties: Soft (silken), firm, flavored, fried — more variety than most Western stores. Natto: Fermented soybeans — a health food that divides opinion. Try it if adventurous. Dashi packs: Individual filter bags of kombu + katsuobushi for home broth-making — excellent souvenir for food-minded travelers. Mirin: Sweet rice wine essential for Japanese cooking — hard to find outside Japan, good quality in supermarkets at good prices.
Self-Checkout (Serufu rechji)
Many Japanese supermarkets have self-checkout — the interface is usually Japanese-only. Steps: scan items one by one · place in bagging area · pay by cash (insert notes then coins) or IC card/credit card. Bags: asked if you need a bag (most Japanese bring their own). Produce with price labels stuck on: scan the sticker barcode, not the item. Staff nearby to assist if confused.
