Taisei Kōki (大成光機) is a Japanese camera maker that was active after World War II.
It is said that the company Fuji Kōgaku was split in two parts after the war: Taisei Kōki and Katsuma Kōgaku, with the latter keeping the Lyra brand name. (Fuji Kōgaku and Katsuma both used the brand name Lyra on various cameras.)
All three companies Fuji Kōgaku, Katsuma Kōgaku and Taisei Kōki used the Terionar lens name, and they have similar logos, showing a cemented doublet lens scheme, with a protuberance on top, maybe an allusion to the Mount Fuji. The logo used by Taisei Kōki on the Welmy range is written TAISEI WELMY.
