Kitazato

What Kitazato does

Kitazato Corporation is a Japanese medical-device company founded in 1998 and headquartered in Fuji, Shizuoka, that develops, manufactures, and distributes consumables and instruments for assisted reproductive technology (ART). Its core technology is vitrification — most notably the proprietary Cryotop® Method (launched 2000), an open-system, minimum-volume device for oocyte and embryo cryopreservation that became the field standard. The portfolio spans the full IVF lifecycle across six categories: vitrification devices and media (Cryotop®, Ultra-Fast Vitri, HPC-based vitrification/thawing media), micromanipulation tools (ICSI injection, holding, biopsy, and PZD pipettes), culture media and oils (Hypure® Oils with endotoxin levels below 0.1 EU/ml, Gamete Buffer, Fertilization Medium, Flushing Buffer, sequential and single-step culture media), andrology media (SepaSperm®, PVP, Sperm Freeze), oocyte retrieval needles (single- and double-lumen, 16G–21G), and catheters (EC-PRO Straight ET, Precurved ET, RYDEN™ echogenic ET, IUI, and the Towako® Method for transmyometrial transfer). The product set exceeds 550 SKUs.

Revenue is generated primarily through direct sales of medical devices and consumables to IVF clinics, fertility centers, and andrology laboratories, supplemented by licensing/royalty components for the Cryotop® Method. No public pricing is disclosed; transactions are routed through authorized distributors. Kitazato serves more than 3,000 clinics across 80+ countries via a hybrid go-to-market combining channel partners (Biomedical Supply/Dibimed in EMEA, Kitazato Dibimed USA and UK in North America/UK, plus regional distributors in APAC, LATAM, Africa, and MENA) and enterprise field sales with product specialists who deliver hands-on workshops and training. The company holds MDR CE (notified body 2797) and FDA clearances on key products, and trades on the Tokyo Stock Exchange under ticker 368A.
