How it works

Japanese sizes are generally smaller and cut differently than western sizes. Shoe sizes in Japan are measured in centimeters (cm). Clothing sizes (S, M, L) are typically one size smaller than their US/EU equivalents. Select the Japanese size you see on the tag to find its approximate equivalent.

Example

Scenario: You find a great shirt labeled "L" and sneakers labeled "27" in Tokyo.

  • Shirt (L): In Japan, a Large is equivalent to a US/International Medium.
  • Sneakers (27): 27 cm translates to a US Men's 9, US Women's 10, UK 8, or EU 42.

Verdict: Always try clothes on if possible, as sleeve lengths and shoulder widths in Japan are often narrower and shorter than western equivalents.

FAQ

Why do my shoes fit differently even if the conversion matches?

Japanese shoes are often designed for wider feet (typically designated as 'E', 'EE', or 'EEE' width). If you have narrow feet, you might need to size down or use insoles.

Are UNIQLO sizes in Japan the same as UNIQLO in the US/Europe?

No. UNIQLO clothing sold in Japan is cut for the Asian market. A size 'M' in Japan is usually equivalent to a size 'S' in the US or Europe.
