Japanese Clothing Sizes for Women 

General size chart

Japanese women’s clothing is typically smaller than Western sizes, so it’s common to select a size or two larger than you might in the US or UK. For example, a US size 4 may correspond to a size 9 in Japan. However, brands vary, so checking the size chart for each store or brand is recommended.

Women's dresses

Women’s dresses in Japan often run slim and fitted, making them smaller than the US or European sizes. For a comfortable fit, you may need to go up by one or two sizes, especially in more fitted or tailored styles. This adjustment allows for better movement and aligns with Japanese sizing standards.

Bra sizes (Cup vs. Band sizes)

Japanese bra sizing uses cup and band measurements similar to Western countries, but they tend to run smaller.

Japanese cup sizes are typically a size or two smaller than US sizes, so a US B cup may need a Japanese C cup for a comparable fit. Band sizes are measured in centimeters, with increments of five rather than the two-inch increments found in the US and UK.

Women's underwear

Japanese women’s underwear is usually labeled in sizes like S, M, and L but often fits more snugly than Western sizes. Choosing a size larger than usual can help achieve a comfortable fit, especially in more form-fitting styles.

Women's pants and jeans

Women’s pants and jeans in Japan are measured by waist size in centimeters, which may differ from the inch measurements common in the US. Japanese pants often run one to two sizes smaller. It’s helpful to know your waist size in centimeters and consider going up a size for a looser, more comfortable fit.

Women’s shoe sizing

Women’s shoe sizes in Japan are measured in centimeters, different from the inch-based sizing used in the US. Japanese shoe sizes for women start smaller, so it’s best to refer to a conversion chart to find the equivalent size in centimeters to match your US size.

Here's a general size chart for Women's Shoe Sizing in Japan. Note that Japanese shoe sizes are usually measured in centimeters, and it's best to measure the length of your foot for an accurate fit.

Men’s Clothing Sizes in Japan

Men’s shoe sizes

In Japan, men's shoe sizes are based on centimeters, which can make it challenging for visitors used to US, UK, or EU sizing. Generally, a Japanese shoe size 27 cm aligns with a US size 9 or UK size 8.5.

For those with larger feet, finding sizes above 28 cm (US size 10) may be difficult in typical stores, though specialty shops and online options are available for extended sizes.

Men’s shirt collar sizes

When selecting men’s shirts in Japan, note that Japanese shirt collar sizes differ from US and UK measurements. The collar size in Japan increases by one unit for each half-size increase in US/UK standards. 

For instance, a US/UK size 15 collar is a Japanese size 38. This slight adjustment helps ensure a more tailored fit in Japanese sizing, and it's helpful to check collar sizes closely when purchasing.

Men’s Underwear

Men’s underwear in Japan follows a standard size range from S to 4L, though Japanese sizing often runs smaller than Western counterparts. A Japanese medium (M) might fit more like a small (S) in US sizes, so it’s wise to consider going up a size for a comfortable fit, especially if you’re accustomed to Western sizing.

Men's suit 

Men’s coats and suit sizes in Japan usually follow a pattern similar to shirt sizing, where a Japanese medium roughly matches a Western small. For example, a chest size of 38-40 inches corresponds to a Japanese medium.

For those seeking tailored fits, jackets and suits in Japanese stores may have a slightly tighter fit, so trying on jackets in-store can help ensure the right feel and look.
