Isetan Shinjuku's Creators floors back two young labels this month, one built on a carbon-capture textile, one on made-in-Japan tailoring
Isetan Shinjuku is running two AW26 pop-ups from young Japanese labels this month: doublet's Re-Style shop built around a garment made partly from a material developed from CO2-consuming microorganisms, and vowels' Men's Creators pop-up built on an all-domestic-manufacture collection — a reminder of what actually earns space on the store's design floors.
Isetan Shinjuku is hosting two pop-up shops from young Japanese labels this month, both part of the store's 2026 autumn/winter design-floor line-up, according to store announcements posted on the Mitsukoshi Isetan site.
On the third floor, in the Re-Style section, doublet runs a pop-up from Aug. 12 to 25 built around a collection it calls "AIR." The centrepiece, per the store's own description, is a garment made in part from what Isetan calls an "innovative material" developed from microorganisms that consume carbon dioxide and other greenhouse gases from the air, with the collection styled around the idea of a form built from something invisible. Isetan is also selling two shop-exclusive T-shirts at ¥24,200 each, one packaged in an air-cushioned pouch; other pieces in the collection run up to ¥231,000 for footwear.
On the sixth floor, in the Men's Creators section, vowels runs a shorter pop-up from Aug. 12 to 18 for its latest collection, "PERFECT DAY." Isetan's announcement describes vowels as a label working across Tokyo and New York design sensibilities and states that every item in the collection is manufactured domestically in Japan. The line pairs double-breasted suits and overcoats with everyday pieces — woven shirts, knitwear, denim — in a palette of moss green, burgundy and deep purple, with tulip and alpine-ski motifs running through the textiles; prices range from around ¥16,500 for a T-shirt to ¥97,900 for a suit jacket.
Neither pop-up is large enough to move Isetan's numbers on its own, but together they say something about how the store curates its Creators floors: doublet gets space for a genuine materials claim rather than just a new print, and vowels gets it for the more old-fashioned pitch of domestic manufacturing done well. For a department store competing for young shoppers against direct-to-consumer labels online, that is the actual product being sold on these floors — a reason to visit that a webstore cannot easily replicate.
