What do people get wrong about reading a Japanese food label?
This answer is a draft. It stays unpublished until legal review and source verification are complete.
Japanese packaged food carries one of the world's more detailed labels: two kinds of date, a full ingredient list in descending order, allergens in brackets, and a nutrition panel. Residents read it in a glance; newcomers see a wall of kanji. Six fields cover almost everything.
The six fields (一括表示, the boxed panel)
| Heading | Reads | What it tells you |
|---|---|---|
| Name (名称) | meishō | Product type (e.g. soft drink 清涼飲料水; confectionery 菓子) |
| Ingredients (原材料名) | genzairyō-mei | Ingredients in descending order by weight; additives after a slash "／"; allergens in brackets e.g. "contains wheat and milk ingredients" （小麦・乳成分を含む） |
| Net contents (内容量) | naiyōryō | Net weight or volume |
| Best-before / use-by date (賞味期限 / 消費期限) | shōmi / shōhi kigen | Best-before (quality) / Use-by (safety) — see below |
| Storage method (保存方法) | hozon hōhō | Storage: room temp (常温), refrigerate at 10°C or below (要冷蔵, 10°C以下), frozen at −18°C or below (冷凍, −18°C以下) |
| Manufacturer / seller (製造者 / 販売者) | seizōsha / hanbaisha | Manufacturer or seller, with address |
The two dates
| Word | Meaning | Applies to | After the date |
|---|---|---|---|
| shōmi kigen (賞味期限) | Best before — the maker's quality date | Foods keeping more than ~5 days: snacks, canned, dry, frozen | Usually still edible; judge by condition |
| shōhi kigen (消費期限) | Use by — safety limit | Perishables: bento, sandwiches, fresh cakes, raw meat | Do not eat |
- Dates read year.month.day (e.g. 2026.09.08 or 26.9.8); long-life items may show year and month only.
- Nutrition panel (栄養成分表示): energy (エネルギー kcal), protein (たんぱく質), fat (脂質), carbohydrate (炭水化物), salt equivalent (食塩相当量) — mandatory since April 2020; per serving or per 100 g as stated.
- Origin: since 2022, the country of origin of the main ingredient is required on all processed foods (原料原産地).
[Verify] Field requirements with the Consumer Affairs Agency's Food Labelling Standards; nutrition and origin labelling dates with CAA notices.
Misunderstanding 1｜The date is a use-by date
Most packaged foods carry a best-before date (賞味期限) — a quality date. The use-by date (消費期限) is the safety one, and it is only on perishables. Learn to tell the kanji for "taste" (味) from the one for "consume" (費).
Misunderstanding 2｜Ingredients are in random order
Descending by weight, like most countries. Additives come after the slash (／). The first three ingredients tell you what the food mostly is.
Misunderstanding 3｜Allergens are somewhere else
They are in brackets inside the ingredient list or summarised at its end: "contains, in part, …" (一部に〇〇を含む). Eight are mandatory (see the allergen article).
Misunderstanding 4｜"Salt" will be listed as sodium
Japanese panels show salt equivalent in grams — directly comparable to the 7 g daily target — not sodium in milligrams.
Misunderstanding 5｜A camera translator is enough
It helps with ingredients. For dates and storage, learn the two kanji pairs and the words for "keep refrigerated" (要冷蔵) — they are the fields where a mistake matters.
