Japanese Shoe Size Converter
Japanese shoe sizes are refreshingly literal: the number on the label is your foot length in centimetres. JP 26 means a 26 cm foot; JP 24.5 means a 24.5 cm foot. The same scale applies to men, women and children, so there's no separate gender chart on the JP side.
Use the converter below to translate any JP size into US, UK, EU and other systems. It defaults to JP 24 (a common women's size in Japan).

Frequently asked questions
How do Japanese shoe sizes work?
Japanese shoe sizes equal foot length in centimetres. JP 26 means a 26 cm foot, JP 24.5 means a 24.5 cm foot. The same scale is used for men, women and children, which makes it one of the simplest sizing systems in the world.
What is JP 26 in US shoe size?
JP 26 is approximately US men's 8 and US women's 9.5. Because Japanese sizing maps directly to foot length, the US conversion changes between men's and women's scales even though the JP number stays the same.
Are Japanese shoe sizes the same for men and women?
Yes - JP sizes are unisex and measure foot length directly, so JP 25 means the same foot for everyone. The US and UK conversions, however, are different for men's and women's because those systems use separate scales.
