Sun Edi Corporation

Hiko Sato, who had been researching ceramic materials since before the war, founded Sun Edi Corporation on March 23, 1950, in Suginami Ward, Tokyo, with the credo of "starting from material development and moving to product commercialization." He developed and commercialized titanium oxide ceramic capacitors, established mass production systems, and set up the headquarters in Suginami, Tokyo. Founder and first president, Hiko Sato, operated sales offices at the Kyuwa-do Building (Chiyoda-ku, Tokyo).

Hiko Sato established Sun Yuden Co., Ltd. in Suginami Ward, Tokyo.
