What Unisis does

Unisis Corp. Japan (株式会社ユニシス) is a privately held Japanese medical device company founded in 1978 and headquartered in Tokyo, specializing in the design, manufacture, and sale of specialty medical needles. Core products include spinal anesthesia needles (in K-3 Lancet, Pencil Point, Distal Fine, and Stiletto Point variants), epidural anesthesia needles and kits (Uniset, Uniset S/E, Uniset Pediatric), nerve block needles (including Echo-Genec echogenic variants), combined spinal-epidural (CSEA) needles, L.O.R. syringes, oocyte collection needles, surgical puncture needles, low-invasive micro injection and ophthalmic needles (31G/34G), low dead space syringes, artificial nose filters, and a veterinary line. Differentiated manufacturing IP includes Engrave加工 for ultrasound visibility, Distal Fine tip tapering with 2-gauge differential over a 7mm tip section for reduced dural damage, ultra-thin-wall tubing that delivers ~30% larger inner diameter for superior CSF recall-back, cobalt-reduced SUS304 stainless tubing for EU MDR compliance, and a patented catheter connector with dual-lock internal screw geometry; the company holds at least 17 registered patents across Japan, the US, and Europe.

The business operates a fully integrated 100% Japan-based manufacturing model across three sites — Saitama (mother factory, established 2004), Hokkaido (established 2014-2015 for BCP, expanded 2022), and Kyushu (under construction, opening Fall 2026) — supported by a network of cooperative companies from Hokkaido to Kyushu for parallel production. Products are sold under the UNIEVER trademark through (i) direct sales to hospitals, clinics, and anesthesia/pain specialists via domestic and overseas sales departments based in Tokyo, (ii) OEM/ODM manufacturing for major global medical device brands and dealers in approximately 50 countries, with 85%+ of production exported, and (iii) sales of co-developed alliance products such as artificial nose filters in Japan. Distribution relies heavily on in-person engagement at medical academic conferences (Japan Anesthesia Society, Japan Pain Clinic Society, etc.) and international exhibitions (MEDICA, Arab Health, KIMES, Hospitalar, Medical Fair Asia/India).

Revenue is not publicly disclosed. The company is family-controlled (Saito family; Eiya Saito serves as Representative Director since 2009), with 178 employees as of August 2025, ISO 13485 and ISO 9001 certifications (since 2003-2004, certified by SGS), FDA registration since 1996 with 510(k) clearances for spinal, epidural, and nerve block needles, CE marking since 2005 (under MDD, transitioning to MDR via TÜV Rheinland), GMP certification since 1995, ANVISA and KFDA approvals, and recognition as a METI Regional Future Driver Enterprise (2017).
