1952

Kofuku Sangyo Co., Ltd. released a spotting scope for the first time in Japan.

As the first spotting scope models in Japan, "TS-1, TS-2" were released. They were selected as official tools used in the shooting event in the 1964 Tokyo Olympics and became popular models sold for 36 years from the release.

1953

A projection lens for CinemaScope (anamorphic lens) was produced and released.

CinemaScope is a widescreen method developed by 20th Century Fox. Kowa Koki produced and sold the lenses after making an agreement with 20th Century Fox to obtain the sales rights in Japan and Southeast Asia.

Became the first Japanese manufacturer to install large sightseeing binoculars (on the roof of Maruei Department Store, Nagoya).

The first four units were installed on the roof of Maruei Department Store in Nagoya. With a 10 yen coin, people were able to enjoy the view for 3 minutes.

1954

The 6cm x 6cm format TLR camera "Kalloflex I" was released.

The first camera released by Kowa Koki. It was a semi-automatic twin-lens reflex camera with a self-cocking system, and it took five years to develop this 35mm camera adopting a 24 x 32mm size, so-called Japanese format.

1955

In 1958, the electric machinery division was newly established in order to launch our own domestic sales. With the establishment of the Kowa Electric Machinery Research Laboratory, the structure of the electric machinery division was completed, from production to sales.

An interchangeable lens for the 8mm cine camera and a filming lens for CinemaScope were displayed at the Brussels World Exposition and an honorary award was received.

In the optical division in the first half of the 30s in the Showa era, lenses and eyeglasses such as binoculars, spotting scopes, and filming lenses for CinemaScope were steadily produced. In the camera field, the market needs quickly changed from twin-lens reflex to the 35mm camera. Therefore, Kofuku Sangyo Co., Ltd. produced new products for the 35mm camera for worldwide introduction.

1959

Mass production of small-size tape recorders and transistor radios was started.

Production of the six-transistor radio "KT-61", 8-inch portable television "TV-82" and super small tape recorder "Micro Corder ER-2" was started.

"Ramera", a 16mm format camera integrated with a radio, was released.

Having a Prominar 23mm F3.5 lens with shutter speeds of B, 1/50, 1/100, 1/200 seconds, this model ran on 9V 6P batteries and had only the minimum function as a camera. It was developed with a playful spirit as a manufacturer.

The first Kowa Planetarium was delivered to Miya Planetarium in Gamagori, Aichi.

1960

The optical division and electric machinery division are integrated into the electric optical division.

Production of the six-transistor radio "KT-61", 8-inch portable television "TV-82" and super small tape recorder "Micro Corder ER-2" was started.

"Kowa Kid", a camera for beginners, was released.

A camera for beginners with a slightly heavy body. It has a 70mm F11 fixed-focus lens and shutter with two speeds, and can take 4 x 6.5cm and also 4 x 4cm format pictures by inserting a mask.

1962

The retinal camera "Kowa RC" was released.

As a new field to apply the optical technology, "medical equipment" was focused on. It occupied a 90% or more share of the handheld type retinal camera market in the world.

The second Kowa Planetarium was delivered to the Children's Hall in Hamamatsu.

1963

In Kowa Company, Ltd., factory names were changed from "Kowa Koki" to "Gamagori Factory" and from "Kowa Electrical Machinery Research Laboratory" to "Chofu Laboratory".

Kowa Company, Ltd. established the U.S.-based affiliated company "Kowa Camera Corporation".

Regarding sales of Kowa Company's electronic optical products in the U.S., "Kowa Camera Corporation" was established exclusively for electronic optical products, and the optical products were sold via this company.

1968

Sales of lenses for surveillance were started.

1970
1972

The affiliated company "Kowa Co., (Thailand) Ltd." was established.

Kowa advanced into Thailand as an affiliated member of the UTO Bangkok branch together with Itoman and Shinko Sangyo in 1956. As the branch was dissolved in 1967, Kowa Company's independent representative office opened, which became the affiliated company "Kowa Co., (Thailand) Ltd." in 1972.

1976

The wide angle retinal camera "RC-W" was released.

Since the first retinal camera was released, only handheld type products had been developed to meet unique demands. As medical treatment advanced, however, retinal cameras began to be required to have more sophisticated specifications and functions, which resulted in development of this new large-size fixed-type model.

1979

The character and graphic display equipment "CG-800" was developed.

Character display equipment utilizing flying spot scanner technology had widely been used in the broadcasting and electric railroad industries. With improvements in semiconductor elements, it became easier to purely electronically synthesize characters and graphics, which contributed to development of the character and graphic display equipment "CG-800". The products were delivered to broadcasting stations throughout Japan.
