The Tōkō (トーコー) is a Japanese camera using the no-need-darkroom process, reportedly advertised by the company Tōkōdō from October 1930, at the price of ¥1 for a set. It is said that the first advertisement appeared that month in Photo Times. The name similarity with the Tougo (Tōgō) cameras was probably intentional. The camera was probably shaped as a box, but this is currently unsure. No surviving example has been observed so far.
