Osaki Medical Corp.

What Osaki Medical Corp. does

Osaki Medical Corp. (オオサキメディカル株式会社) is a Japan-headquartered, privately held medical materials manufacturer founded in 1936, operating from Nagoya with approximately 400 employees as of October 2025. The company manufactures and distributes medical supplies across three primary verticals: medical/surgical consumables (medical gauze, medical absorbent cotton), nursing and elder-care products (under the PLUS HEART brand), and obstetrics/gynecology and maternal/infant products (under the dacco brand). It holds documented No. 1 market share in Japan for medical gauze, medical absorbent cotton, and maternity delivery sets, supported by its proprietary world-first automatic gauze cutting and packaging line, ISO9001:2015 and ISO13485:2016 certifications, ISO7–ISO8 cleanroom environments, and ethylene oxide and moist-heat sterilization capabilities across three domestic factories (Iwakura, Gujo, Kani) and an Indonesian subsidiary (PT. Osaki Medical Indonesia, Pasuruan).

The company monetizes through a hybrid B2B and direct-to-consumer model. Roughly ten regional sales offices and four logistics centers serve enterprise customers — hospitals, clinics, and nursing care facilities — alongside OEM/ODM contract manufacturing for pharmaceuticals, medical devices, quasi-drugs, and cosmetics. On the consumer side, Osaki operates its own e-commerce platform (store.osakimedical.co.jp) with free shipping over ¥5,500, runs branded storefronts for dacco and PLUS HEART, and lists on Amazon Japan. FY2025 sales revenue stood at 26,480 million JPY, generated primarily through unit-pricing on consumables and contract manufacturing service fees. International operations extend through subsidiaries and partners in Indonesia, Vietnam, China, and — as of December 2025 — India via a partnership with Soothe Healthcare targeting feminine hygiene, maternity, and baby care categories. Customer concentration is spread across multiple institutional segments and thousands of individual consumers, with no single named large customer materially disclosed.
