Japanese supermarkets (スーパー supa) are well-stocked, clean, and efficient — but the first few visits can be disorienting if you can’t read labels. This guide helps foreign residents navigate the layout, decode packaging, and shop confidently.
Major Supermarket Chains

Store Layout
Japanese supermarkets typically follow a consistent layout: fresh produce (野菜・果物) near the entrance, followed by meat/fish sections, then processed foods, dairy, and frozen. Ready-made meals (惣菜 sozai) are usually near the checkout area or a dedicated deli counter. Alcohol occupies its own aisle. Non-food items like detergent and toiletries are usually in a separate section at the back or side.
Reading Labels: Key Terms
You don’t need to read Japanese fluently to shop — a few key terms cover most situations:
- 消費期限 (shōhi kigen): “Use by” date — strictly followed for raw meat, fish, prepared foods. Don’t eat after this date.
- 賞味期限 (shōmi kigen): “Best before” date — applies to preserved goods (canned, dried, processed). Quality may decline after but not necessarily unsafe.
- 原材料名 (genzairyō mei): Ingredients list — allergens are highlighted in bold in Japanese labeling
- 内容量 (naiyōryō): Net weight/volume
- 産地 (sanchi): Origin/production region — Japanese consumers pay attention to this, especially for fish and rice
- 国産 (kokusan): Domestic (Japanese) origin
Meat and Fish Sections
Meat is almost always pre-sliced in Japanese supermarkets. Thin-sliced beef (薄切り usugiri) and pork are used for shabu-shabu, sukiyaki, and stir-fries; thicker cuts are less common but available. Chicken is sold both whole pieces and sliced. Fish is typically whole, filleted (切り身 kirime), or prepared sashimi-grade depending on the store’s quality level. The fish section may feel overwhelming initially — focus on pre-packed fillets for easy cooking.
The Discount Sticker System
This is one of the most practically useful things to know: time-based discount stickers (値引き nerubiki or 割引 waribiki) are applied to approaching-expiry items, typically 1–3 hours before closing. Common markings:
- 半額 (hangaku) — 50% off
- 30%引き — 30% off
- 20%引き — 20% off
Prepared sushi, sashimi, bento, and deli items are the most commonly discounted. Strategically shopping near closing (typically 9–11pm for urban stores) can significantly reduce food costs.
Self-Checkout and Bagging
Self-checkout (セルフレジ) is increasingly common in Japanese supermarkets. In Japan, baggers are rare — you take your basket to the bagging counter and pack your own bags. Most stores encourage bringing your own bags (エコバッグ eco bag); plastic bags cost ¥2–5 each under national law since 2020. Loyalty point cards (ポイントカード) are offered by most chains — worth getting for frequent shoppers.
Useful Food Items to Know
- Mirin (みりん): Sweet rice wine for cooking — cooking mirin (料理用みりん) is in the condiments aisle
- Dashi (だし): Stock base — instant dashi packets (だしパック) are a kitchen essential
- Natto (納豆): Fermented soybeans in the dairy/chilled section — acquired taste but nutritious
- Tofu (豆腐): Multiple varieties; 絹 (kinu/silken) vs. 木綿 (momen/firm) — key distinction
- Mentsuyu (めんつゆ): All-purpose noodle soup base that doubles as seasoning for many dishes
Once you’ve done a few shops, Japanese supermarkets become among the most pleasant grocery experiences anywhere — excellent quality, clear organization, and genuinely good ready-to-eat options throughout the day.
