"Mangesai" is the brand name of Osamu Omori. A kaleidoscope displays different beautiful patterns each time you look through it. Osamu Omori is an artist like a kaleidoscope; the unique talent hidden within him reflects and refracts light, creating infinitely expanding, beautiful, non-geometric patterns. Kazuo Fujisawa, who is managing Fujisawa Maki-e in Iiyama, Shinshu, found Omori's talent, who lives in Wajima, Noto, and proposed holding Osamu Omori's first solo exhibition at Wako in Ginza, Tokyo, Japan. "Inori no Art" proposed the brand name "万華才 (Mangesai)" for the activities of Osamu Omori and Kazuo Fujisawa, and has been supporting the planning and management of their art activities.
