About Us

Jokoh has contributed to advances in healthcare over a history spanning 70 years. Our main business is the research, development, production and sale of medical apparatus, medical consumables and invitro diagnostic kits. We were the first company in the world to incorporate a dialysis fluid measurement mode into electrolyte analyzers, which we produce ourselves, and we provide electrolyte analyzers which also serve as analyzers for concentration of dialysis fluid. Our aim is to work with partner institutions to improve the management of concentration of dialysis fluid through the use of analyzers for concentration of dialysis fluid. Jokoh started its first branch in Tokyo and has established an extensive sales network, with around 20 branches and sales offices throughout Japan. We also market our products in approximately 40 countries worldwide, especially in Asia.
