Outside of MUJI Store in NYC

A comprehensive guide for shoppers who want to understand how MUJI clothing sizing and price differ in Japan versus in the US.

When I first started visiting Japan in 2013, I was really excited to shop at UNIQLO and MUJI – two very popular Japanese brands that I was familiar with because they had opened shops in New York City, where I lived at the time.

As I already recounted in previous posts, I’d never really been successful at shopping for clothing in either store while in the US. As a petite Asian woman under 5’3″, I was hopeful that the sizing in Japan would be more of an “Asian fit” (aka – slimmer cut) and the selection of clothing would be wider so I’d be able to snatch up a ton of great items to wear back in the US.

I’ve gotten a lot of amazing feedback on my Japan vs. US UNIQLO size comparison blog post from travelers who were curious to know more about how sizing in Japan differs from the US. Recently a reader asked me more about whether sizing for MUJI in Japan was also different from other countries where their clothing is sold and that got me thinking I should write a post dedicated to shopping for MUJI clothing in Japan!

TLDR version:

• Japanese MUJI sizing is generally one size smaller than the US version.
• Based on sizing charts, for most items, you need to go one size up in the Japanese size to get an equivalent US fit (e.g. – JP S = US XS), however, the item length is generally shorter in Japan than in the US, even if you size up.
• Japan’s XS size is the smallest size made by MUJI, but has no equivalent in the US since MUJI US does not carry XXS. Very petite women will want to stock up on Japan XS because they can’t get it back in the US.

But now let’s take a look at some specific examples.

The MUJI US site has a size chart, but it does have a caveat saying that individual items may have slightly different sizing:

Unfortunately, the MUJI Japan does NOT have a universal size chart on their site we can compare 1:1 with the US chart. Instead, they publish individual size charts for every item on its website, so let’s look at a few specific examples of the sizing listed on the MUJI Japan site versus the US site.

I found the Extra Long Staple Cotton Broad White Shirt I bought when I was last in Japan on both the US and Japan MUJI sites.
