History
Founded in 2017 by Hiroki Sugiyama, began its business with the planning and wholesale distribution of water-pressure-operated bidets.
As Japan transitioned through the Heisei and Reiwa eras, the company advanced into the development of hybrid-type warm-water bidet seats.
Through OEM manufacturing for clients, import and export operations, and supplying products to embassies and the Japan Self-Defense Forces, Sugihan has built a strong reputation based on trust and proven performance.
