What STX does

STX Co., Ltd. (株式会社ＳＴＸ) is a Tokyo-headquartered textile specialty trading company that traces its yarn-trading origins to 1898. As of April 2026 it employs 197 people, holds ¥830 million in registered capital, and operates as a wholly-owned subsidiary of Chori Co., Ltd., a Japanese trading group, following a share transfer from Sumitomo Corporation in June 2021 and a rebrand from Sumitex International Co., Ltd. in January 2022.

Its core business spans four segments: textile raw materials (yarn and fiber procurement from Japan and 11 overseas countries, sold to 200+ buyers across 9 countries); baby and kids apparel (OEM/ODM production for children's clothing chains); men's and women's apparel (serving select shops, manufacturers, specialty stores, and TV shopping channels); and character goods and sundries (including licensing intermediation, tableware, stationery, and accessories). Production is anchored by a wholly-owned sewing facility in Vietnam (STX Vietnam) with annual capacity of approximately 1 million garments, supplemented by partner factories in China, ASEAN, and Bangladesh, alongside wholly-owned trading operations in China and offices in Osaka and Hong Kong.

STX monetizes primarily through B2B transaction-based trading of yarn and textiles and OEM/ODM apparel manufacturing fees, with a smaller direct-to-consumer layer through its proprietary CONFIL organic-cotton brand e-commerce site and Makuake crowdfunding launches of branded products. It monetizes its material expertise through intangible assets including the SUVINPIMA® registered trademark (a proprietary Suvin Gold/Pima cotton yarn blend), the CONFIL organic cotton brand, Synchro Thermo temperature-regulating batting, and Ramie 4 high-grade ramie. The company holds WRAP Gold certification at its Vietnam facility (obtained 2022, renewed 2024), Oeko-Tex Standard 100 certification, and AEO customs status.

Highly comparable business model across trading and OEM/ODM functions.
