The Lyraflex is a Japanese 6×6 TLR that was made in the 1950s by Katsuma Kōgaku. The taking and viewing lenses are geared together for focusing. Film advance is by knob and is controlled by one red window in the back, protected by a vertically sliding cover.

According to McKeown, there are two versions, both with Terionar 80/3.5 lens[1]. The early one has a Fujikō F shutter (B, 1–200[2]) and the later one has a Fujikō P shutter with added synchronization[3].
