Sizing in Japan and Asia
- Japanese clothing runs about one size smaller than US or EU labels of the same letter: a US M is often a JP L. Try on before you buy; most shops have a fitting room (shichakushitsu) — take shoes off before stepping in.
- JP shoe sizes are foot length in centimetres (25 = 25 cm). Measure your foot at home and add 0.5–1 cm; Japanese lasts are often wider at the toe.
- “Free size” (フリーサイズ) means one size, usually cut for about a JP M.
- LL, 3L, 4L are Japanese XL, XXL, 3XL. Large and tall sizes sit in separate shops or online; department stores have a large-size floor.
- Vietnam: ready-to-wear is cut small (a Western M is often a VN XL). Tailors in Hội An and Hanoi make shirts and suits in 24–72 h; bring a garment that fits as a pattern.
- Uniqlo, Muji and other chains print the same S/M/L across Asia but cut Asian-fit: check the cm chart on the tag.
- Kids: Japan and much of Europe label by child height in cm; measure height before the trip.
- Brands differ. These charts are the common retail conversions, not a promise for any one label.
