What KSK does

KSK Co., Ltd. (株式会社ケーエスケー) is a private medical comprehensive trading company (医療総合商社) headquartered in Osaka, Japan, founded in 1962. The company operates six core business segments: pharmaceutical wholesale, nursing care products, medical devices/reagents/food, vaccine distribution, clinic opening support, and femtech. It serves hospitals, medical clinics, pharmacies, and nursing care facilities across the Kansai region (Osaka, Kyoto, Hyogo, Shiga, Nara, and Wakayama prefectures) through a direct sales force and an integrated logistics network comprising GDP-compliant distribution centers in Hyogo, Kyoto, and Osaka. The Hyogo Logistics Center was awarded ISO9001 certification in November 2024 and operates a 608.7 kW self-consumption solar power system reducing CO2 emissions by approximately 249 tons annually.

KSK generates revenue primarily through transaction-based B2B wholesale distribution of pharmaceutical, medical device, and nursing care products, supplemented by professional services (clinic opening support) and e-commerce (femtech video sales via L-Care Store). The company operates three wholly owned subsidiaries (Vital KSK, HMI, and Vital Net) and is expanding its digital ecosystem through the Tsunagu TV video platform (launched December 2025) for healthcare professional networking and the Arukana Mill customer portal (launched May 2025). KSK maintains extensive local government partnerships across the Kansai region covering community health promotion, cancer screening awareness, and elderly care initiatives. The company has been consecutively certified as a Health Management Excellent Corporation (健康経営優良法人) from 2023 through 2026.

In December 2025, KSK completed the acquisition of Yachiyo Care Holdings Co., Ltd. as a consolidated subsidiary, signaling vertical expansion into nursing care services. The company also entered a strategic collaboration with Hitachi in September 2025 to pursue digital transformation of pharmaceutical delivery operations. KSK employs between 1,001 and 5,000 people and remains privately held with no disclosed parent company or public listing.
