Haiseni Co.
ハイセンヰ株式会社
A long-established knitwear-focused OEM/ODM company based in Kanda-Sakumacho, Tokyo. Originating from a yarn trading background, Haiseni is strong in translating brand intent into knitwear through yarn selection, knit structure, dyeing, twisting, fulling, linking, specification design, sample coordination, and production management. Public sources introduce its work with design-sensitive brands such as COMME des GARCONS, UNDERCOVER, and VISVIM, making it better suited to mid-to-premium knit projects such as sweaters, socks, hats, and scarves where texture, silhouette, color expression, and durability matter more than low-cost mass production.
