The Futami Six is a Japanese 6×6cm folding camera, about which very little is known.
The Futami Six is a horizontal folder, with three-part folding struts inspired by the 6×6 Ikonta. The camera can take 6×6cm or 4.5×6cm exposures. The top housing contains two separate viewfinders — one for each format, distinguished by 12E.X. and 16E.X. indications on the rear. The main viewfinder, for 6×6cm, has a square window at the front surrounded by a metal frame; the other viewfinder has a round window imitating the second-image window of rangefinder cameras.
The rest of the top housing is straightforward, with a shutter release on the right, as seen by the photographer, an accessory shoe on the same side, a small button on the left to release the folding bed, and an advance knob at the left end.
The back is hinged to the right for film loading, and is retained by a sliding bar on the left. It contains two red windows, protected by horizontally sliding individual covers, with 16EX and 12EX indications.
The name FUTAMI is engraved on the top housing, together with MODEL I. The words FUTAMI KOKI are embossed in the leather covering on the back. This surely corresponds to the manufacturer, whose name is presumably Futami Kōki.
There is a logo embossed on the front door and at the front of the ever-ready case. There is no engraving on the folding struts, unlike most other folding cameras of the time.
No original document mentioning the camera or its manufacturer Futami Kōki has been found yet. The only surviving example known so far is pictured in an article by Furukawa Haruo in Camera Collectors' News. It has a Seriter lens and an NKS shutter synchronized via an ASA bayonet post. This lens and shutter combination is very common on Japanese folding cameras produced around 1952–3.
