The Germans manufactured Enigma machines for the Japanese Government but they were never received. "Officially" they were lost when the German submarine tasked with the delivery was sunk. Japanese experts, having a very basic shared knowledge of the Enigma, created their own device. Only two surviving examples of the Japanese Enigma are known to exist.

This unit is on display at the National Cryptologic Museum.
