KUME.JP - Kume Sen-i Kogyo
Founded in 1935, a pioneer manufacturer of Japan-made T-shirts.
Founded in 1935 in Sumida, Tokyo, Kume Sen-i Kogyo is a specialist manufacturer that created Japan's first domestically produced outerwear T-shirt, "Iro-Marukubi." From material selection to knitting, sewing and finishing — through an integrated system of domestic factories and craftsmen — Kume Sen-i Kogyo continues to make "T-shirts that only Japan, and Kume Sen-i Kogyo, can create."
PROFILE Company & Brand Story
Kume Sen-i Kogyo was founded in 1935 in the Honjo knitwear district of Tokyo as Kume Mokoso Manufacturing. In the mid-1950s, soon after the war, the second-generation president Shinichi Kume, together with his brother, worked on developing a domestic outerwear T-shirt — leading to the birth of "Iro-Marukubi," said to be Japan's first T-shirt. Since then, as a specialist Japan-made T-shirt manufacturer, the company has continually refined its materials and production methods.
In 1960 it was incorporated as Kume Sen-i Kogyo Co., Ltd., and in 1963 the Chiba factory — capable of integrated cutting, sewing and finishing — began operations. The group also established a print factory, building a system where everything from body manufacturing to print processing can be completed in-house. It continues to produce the long-selling classic T-shirt "SAY YOUNG," along with many collaboration T-shirts with brands and artists.
Under the concept of "a T-shirt that only Japan can create," Kume Sen-i adopts fabrics from domestic spinning and knitting, and is characterized by carefully maintained craftsmanship in sewing and finishing. The cylindrical body and "tenchi-biki" stitching at the hem and sleeve openings are devised to combine comfort with high durability. The aim is a T-shirt whose texture grows richer the more you wear it, lasting for many years.
The company also engaged in environmental considerations from early on, developing organic cotton products as a regular member of the NPO Japan Organic Cotton Association. Through selecting materials that don't work against natural cycles and through manufacturing that lasts thanks to durability, it proposes a sustainable lifestyle.
At the factory shop on the first floor of the headquarters, you can pick up and choose from standard T-shirts and collaboration items. In the past, it has also hosted silkscreen workshops and gallery exhibitions where you can experience the joy of T-shirts. From Sumida, Tokyo, the company continues to deliver T-shirts packed with Japanese technology and culture.
Founded in 1935, the pioneer of Japan-made T-shirts: "Iro-Marukubi"
Founded in 1935 in the Honjo knitwear district of Tokyo, the company developed Japan's first domestic outerwear T-shirt "Iro-Marukubi" in the 1950s. As a pioneer that opened the Japan-made T-shirt market, it continues to make long-selling classics to this day.
Integrated domestic production from material selection to sewing and finishing
Using fabrics from domestic spinning and knitting, the company carries out cutting, sewing and finishing through an integrated process at its own group factories such as the Chiba factory. With craftsmanship packed into specifications such as the circular knit body and "tenchi-biki" stitching, it aims for a T-shirt that resists shape loss even after repeated washing.
Environmentally conscious organic cotton initiatives
As a regular member of the NPO Japan Organic Cotton Association, the company adopts organic cotton for select items including the sustainable line. By selecting materials that align with natural cycles, it pursues both T-shirt manufacturing that lasts and environmental considerations.
