The Gokoku and Ricohl are Japanese cameras taking 3×4cm pictures on 127 film, made by Riken Kōgaku Kōgyō (the predecessor of Ricoh) from 1938 to the war. They have a focal plane shutter and look like the Leica screw models, without a rangefinder. They were not the only 3×4 camera with a focal plane shutter: other examples are the Foth Derby, the Ensign Multex or the French Lumière Elax, Gallus Derlux and Pontiac Lynx II. However they were perhaps the only ones with an exposure counter and film advance fully coupled to the shutter winding.

Possible predecessors: the Lausar and the Baika

The Lausar is only known from a letter by Ōishi Hiroshi (大石博) to the Japanese magazine Kurashikku Kamera Senka.[1] It is a 3×4 camera with a focal plane shutter, of which about ten prototypes were made by the company Tomioka: this was confirmed to Mr Ōishi by the company, the date being told as "at the time of the China events" (支那事変当時), an euphemism designating the war with China which broke out in 1937. According to the pictures, the camera's general aspect and the layout of the controls are very similar to the Gokoku but the body is slightly more angular. The name Lausar is engraved on the top plate above the viewfinder, together with a logo, the company name Tomioka Kogaku Tokyo and the serial number. The speed dial seems to have Z, 30–500 settings. The lens is a collapsible Tomioka Lausar 5cm f/3.5 with a focusing tab and an infinity stop. It is not known if it is interchangeable. The striking design similarity leads to the hypothesis that Riken took over the Lausar project from Tomioka and developed it into the Gokoku.

The Baika (バイカ)[2] is only known from Kokusan kamera no rekishi, quoting a column in the April 1937 issue of Camera Club. It is said to be a 3×4 camera with a focal plane shutter giving B, 25–500 speeds, automatic stop film advance, chrome fittings and a collapsible Lausar f/4.5 lens.[3] It seems that it was presented as a Leica copy, and the name "Baika" itself is very close to Leica (ライカ, raika in Japanese). It is attributed to the department store Ōsaka Daimaru Hyakkaten which was obviously only the distributor.[4] The presence of the Lausar lens by Tomioka and the similarity of the specifications suggests that the Baika was another name for the Lausar camera.

The Riken No. 1

The Gokoku itself was first announced by Riken Kōgaku Kōgyō as the Riken No. 1 (理研NO.1) or Riken Camera (理研カメラ) in advertisements and articles dated October 1938.[5] The pictured camera is identical to the Gokoku but it seems to have no markings above the top plate. The shutter speed range goes from 1/20 to 1/500.[6] The lens looks like it is interchangeable but this is not mentioned anywhere in the original documents. It has a large focusing tab, different from the part normally found on the Gokoku lenses. The lens was said to be a Ukas Anastigmat f/3.5 in the October 1938 Asahi Camera article but it was announced as a Riken Kōgaku Anastigmat f/3.5 in the advertisements and the pictures show the RIKEN 1:3.5 F=50mm engraving.

The Riken No. 1 was available for ¥195 to subscribers only.[7] It seems that the camera was never produced under that name and no surviving example has surfaced so far. It is said that the delivery was delayed and that this caused complaints.[8]

The Gokoku

This section is currently under rework.

Description

The Gokoku or Gokoku No. 1 is a 3×4cm viewfinder camera with a metal body. The viewfinder is offset to the left and is contained in a short top housing. The name GOKOKU N°1 is engraved above the finder together with the R.K.K initials of Riken Kōgaku Kōgyō. The accessory shoe, speed dial and shutter release are above the top housing, to the right of the viewfinder. The speed dial has Z, 20, 30, 40, 60, 100, 200, 500 settings. The serial number is engraved in front of the accessory shoe. At the left end of the top plate there is a fake rewind knob. The advance knob and exposure counter is at the right end. The film is advanced and the shutter is wound in the same movement.[9] Because of the absence of perforations, the film advance mechanism only relies on feeler-rollers and it was plagued with reliability problems.[10]

The back and bottom plate are removable together and they are locked by keys at both ends. The bottom plate also has a tripod thread. The back contains a single red window at the left end, used to set the position of the first exposure. It is protected by a cover that is retracted by a thumbwheel surrounding the red window.

Variations

Two main versions are known: one has an interchangeable lens and the other has a fixed lens.

Riken announced the first Gokoku model with interchangeable lens in 1939 and sales began in 1940. It could take Leica screw lenses and was normally equipped with a Gokoku Anastigmat 50/3.5 triplet lens. This lens was collapsible, with helical focusing and focusing tab, looking like the Leica Elmar 50/3.5. The serial number of the lens is indicated on the distance ring. There is a metal cap engraved RKK.

Later lens interchangeability was abandoned and the Gokoku was sold with a fixed lens, the same Gokoku Anastigmat 50/3.5.

The Gokoku had a B-20-30-40-50-100-200-500 focal plane shutter. The shutter speed selector was above the top housing like on the Leica. The Gokoku was marked above the finder Gokoku No 1 (with a stylized G) and R.K.K. (for Riken Kōgaku Kōgyō). The serial number was in front of the accessory shoe. At the left end there was what looks like a rewind knob, but 127 film do not need rewind, so presumably it was only there to look like the Leica. There was one red window in the back, probably to set the first exposure. The back and bottom plate were removable with two keys.

There was also an accessory shoe, and Riken sold an external rangefinder for the Gokoku, marked RKK and GOKOKU RANGE-FINDER. It was copied on the external rangefinder of the Leica Standard, with a shorter base.

Note: Gokoku is written 護国 and means "Protector of the country", a "patriotic" wartime name.

The Ricohl

Later, around late 1940, Riken completely reworked the mechanism and launched the Riken Ricohl I. It had a longer top housing and a bigger finder. The exposure counter was now inside the advance knob, and there was no fake rewind knob. It was marked Ricohl Mod.I and R.K.K above the finder, and the serial number was in front of the accessory shoe. The Ricohl I had the same Gokoku Anastigmat 50/3.5 lens as the Gokoku, probably in fixed mount.

In 1942 followed the Ricohl IIB (リコールIIB型), with an interchangeable Neutar (?, ノイタール) four element lens. This lens mount was a screw mount specific to this camera. The lens looks even more like the Leitz Elmar 50/3.5.

There is an ad for the Ricohl IIB shown here, dated 2602 in Japanese calendar, ie 1942. The price was 256 yen. In an ad for the Riken Heil shown at the same site, two Ricohl variants are listed: the IIB (barely readable) for 256 yen and another model (looks like Ricohl II or Ricohl III) for 314 yen.

It is said at Ricoh's corporate site that more versions were planned and abandoned because of the war effort.

They also say that the Roico 4x4 camera used the same body, but with a lens shutter.

Serial numbers

An unverifiable source (Japanese seller) says about the Ricohl I that 1500 were produced. It is unknown if this number also includes the Ricohl IIB, or even the Gokoku.

It is said that only very few functioning Gokoku / Ricohl still exist, and even the one exposed at Ricoh's service center is not operational.

Some serial numbers observed:

  • Gokoku: 1168 (probably interchangeable lens No 10168, for sale by a dealer with Gokoku rangefinder), 2818 (reported in a forum)
  • Ricohl I: 3309 (Gokoku lens No 11275, ebay auction), 3600 (Gokoku lens No 11923, pictured in McKeown)
  • Ricohl IIB:
