The Kaitenkei is a Japanese spy camera developed by Tōkyō Kōgaku in the late 1930s. It is said that the camera takes ten exposures on 8mm cine film, has a 13.9mm f/2.8 lens and a guillotine shutter with a single speed setting (1/50).^[1] It is also said that the camera was rejected by the Japanese Army.^[1]

At least one Japanese matchbox camera is known to exist today; it is not known if it was related to the Kaitenkei.
