Japanese Shoe Sizes Explained
Japanese shoe sizing is the simplest system in common use: the number on the label is your foot length in centimetres. There is no men's/women's offset and no kids' restart - JP 24 means a 24cm foot, full stop.
That makes JP sizes the most reliable cross-reference when you're shopping international brands. Use the converter below - pre-set to JP 24 - to translate any Japanese size into US, UK, EU and more.

Frequently asked questions
How do Japanese shoe sizes work?
JP sizes = foot length in cm. JP 26 = 26cm foot.
What is JP 26 in US shoe size?
JP 26 is roughly US men's 8 and US women's 9.5. Because JP sizing is anchored directly to foot length in centimetres, the exact US equivalent can drift half a size either way depending on the brand's last shape.
Are Japanese kids' shoe sizes also in centimetres?
Yes - Japanese kids' sizes use the same centimetre-based system, just with smaller numbers. A toddler shoe might be labelled 17 (a 17cm foot), and the scale runs in 0.5cm steps up into the adult range, so there is no separate kids' numbering to learn.
