Japan is a high-margin market for apparel exports, but its labelling rules form a system of their own: care symbols follow JIS L 0001, composition and labeller details fall under the Household Goods Quality Labelling Act, and imported goods must also carry a country of origin. Many Chinese suppliers simply reuse a GB or ISO file for a Japanese order and get rejected at customs, inspection or on the marketplace.

This guide sets out the legal basis, the mandatory items, the differences between JIS care symbols and ISO/GB, how blend ratios should be written, and how hang tags, main labels and care labels share the compliance load — plus a checklist of the mistakes Chinese factories make most often.

1. Which Rules Govern Clothing Labels in Japan?

Japan's textile labelling requirements come from three layers rather than one law: (1) the Household Goods Quality Labelling Act and the fibre product labelling standards issued by the Consumer Affairs Agency, which fix the mandatory items; (2) JIS L 0001, Care labelling symbols for textiles, which defines the washing, bleaching, tumble drying, ironing and dry-cleaning symbols; and (3) country-of-origin rules for imported goods. Getting only one of the three right can still be ruled non-compliant.

2. The Four Mandatory Categories

ItemRequirementTypical carrier
CompositionFibre names and blend ratios, listed from highest to lowest contentMain label, care label, durable label
Care symbolsWashing, bleaching, tumble drying, ironing and dry cleaning per JIS L 0001Care label (must be durable)
LabellerName and address, or name and phone numberCare label, hang tag or packaging
Country of originMandatory for imported goods, e.g. 原産国：中国Hang tag or care label

3. How JIS Care Symbols Differ From ISO and GB

JIS L 0001 is based on ISO 3758, and most everyday symbols match China's GB/T 8685 — but the details are enough for a Japanese buyer to reject a sample:

  • Japan keeps symbol groups for wringing and for the drying method (line dry in shade, dry flat), which have no exact equivalent in ISO 3758;
  • Some newer ISO symbols are not adopted in Japan, so copying a European symbol chart produces marks the Japanese market does not recognise;
  • Japanese practice is to cover all five groups — washing, bleaching, tumble drying, ironing and dry cleaning — while GB allows selective use; omitting one group can trigger a complaint.
💡 Tip: for Japanese orders, ask the buyer for their current symbol list or a reference label, then we lay out the care label to JIS L 0001 — that avoids version clashes.

4. Writing Blend Ratios That Clear Inspection

The rule is simple: list fibres from highest to lowest content, with ratios adding up to 100%. Three practical notes:

  • Write out common blends such as 65/35 polyester-cotton in full — never just polyester-cotton;
  • Very small fibre shares may be grouped under a general category (such as other fibres), but the threshold follows the latest official notice — do not merge on gut feeling;
  • Ribbing, lining and decorative threads each need their own calculation — missed items here cause a good share of rejections.

5. Splitting the Job Between Durable Labels and Hang Tags

Japan requires care instructions to be durable — sewn in or firmly attached, and still legible after normal washing. Composition and labeller details may move to a hang tag or the packaging only when the product itself cannot carry them.

  • Care label: carries composition plus care symbols, usually sewn into the side seam or the back neck;
  • Main label (woven): brand mark and size; whether it also carries composition is the brand's call;
  • Hang tag: labeller details, country of origin, price and marketing — but it cannot replace the care symbols on the sewn label;
  • The combo: confirm main label, care label and hang tag as one set so compliance information is allocated in a single pass.

6. Six Mistakes Chinese Suppliers Make Most Often

  • Using a GB or ISO file straight away for a Japanese order, so symbols are missing or version-mismatched;
  • Origin written differently on the tag and the care label — 中国製 on one, Made in China on the other;
  • Listing the Chinese factory as labeller when the responsible party should be the Japanese importer or seller — never confirmed in advance;
  • Missing ribbing, lining or decorative thread in the blend ratio;
  • Using film-type care labels that fade or peel after a few washes, failing the durability requirement;
  • Machine-translating the Japanese copy, leaving unnatural wording that hurts the brand;

7. Build Compliance Into the Trim Package Once

For Japanese orders, confirm the trims as one package: main label, care label, hang tag and packaging sampled in the same round and driven by a single composition-and-symbol sheet — so nothing conflicts on arrival.

Dongguan TAGE Packaging supplies main labels, care labels, hang tags and packaging bags as a one-stop programme for brands exporting to Japan, laying out and sampling to the buyer's JIS symbol sheet and composition data — samples in 3–7 days, bulk in 10–25 days, with flexible MOQs.
