What to know about Blue Blue Japan

Indigo dyeing drives the whole line

Collections are built around natural plant indigo in fermented vats, with repeated dipping so garments fade as they are worn rather than arriving pre-distressed.

Japanese craft techniques, not just denim

Shibori, katazome patterning, kasuri shirting and boro-style patchwork show up on sweatshirts, noragi and chore jackets as much as on jeans.

A Tokyo store's house label

Launched in 1996 as the flagship brand of Seilin & Co.'s Okura shop, it is largely made in Japan and now reaches US and European stockists.

How Blue Blue Japan fits

Overall fit

runs small

Shoppers consistently report that Blue Blue Japan uses Japanese numeric sizing that runs about a size small versus US/EU labels, with relaxed but short-bodied cuts and some shrinkage in the heavy indigo-dyed cottons.

Tip: Most non-Japanese buyers go up one size (e.g. a US M usually lands on a size 3), and up two if you are tall or want real layering room.
