What is phi. denim?

phi. denim is a small French and Japanese jeans label that presents itself as a maker of authentic and timeless Japanese denim. It launched in 2015 with a four-person team splitting roles between Japan, where production and PR are handled, and Europe, where marketing, sales and product creation take place.

Products and positioning

The brand focuses on a redesigned five-pocket jean. Its first model used a low rise, relaxed top block and pronounced taper in 14 oz unsanforised, rope-dyed indigo selvedge denim woven in Okayama.

  • Jeans cut and sewn in a small workshop in Kojima, Okayama
  • Each pair numbered and marked with the initials of the person who cut and tailored it
  • Back pockets made from kimono fabrics such as Koushi cotton and Asanoha silk, offered in limited quantities
  • Selvedge edging with red and black detail

The kimono pocket concept limits volumes, since each kimono yields only a set number of pockets depending on its quality.

Why it matters

phi. denim is an example of a niche European label building its proposition on Japanese craft provenance, traceable production and limited editions, themes that resonate strongly in the premium raw denim market.
