BIFURCATUM is a Japanese womenswear brand that officially launched with the Spring/Summer 2026 season.
The designer is Naoko Kawamura, a former pattern maker for Junya Watanabe.

With "Athletic form" as its concept, the brand develops clothing that pursues both functionality and unique sculptural beauty. Another characteristic is its commitment to unique creative projects every season, centered on the theme "Encountering form."

Born following the "Kookaburra" collection presented in Paris—a result of winning a grand prize in a contest while still a student—this is an up-and-coming brand to watch, possessing both solid pattern-making skills and a high level of design.
