Kowa is a Japanese company, which manufactured cameras from 1954 to 1978. It continued to make binoculars and telescopes (among much else), and in 2005 marketed a "spotting scope" with integrated digital camera, thereby again becoming a camera manufacturer of a sort.
|Registration of the Prominar trademark (1947–48). Downloaded from the IPDL, in accordance to the IPDL policies.|
The company was founded in Nagoya in 1894 as a textile shop, and entered the spinning industry in 1919. In 1939, the trading and spinning activities were separated, and the trading company was incorporated as Kōwa K.K. (興和㈱). After 1945, the company attempted to diversify its activities, and created the dependent Kōwa Kōki Seisakusho (興和光器製作所, meaning Kowa Optical Works) in 1946. It produced eyeglasses for a short period, then switched to higher value products such as opera glasses, binoculars, rifle scopes or spotting scopes, some of which were bought by the US forces. It also made projection lenses, both regular and anamorphic (for the CinemaScope process), under the Prominar brand name, whose registration was applied for in 1947 and granted in 1948.
The company entered camera production in 1954 with the Kalloflex 6×6 TLR, then made a series of 35mm cameras with a leaf shutter, some with a fixed wide-angle or tele lens and some with an interchangeable lens. Many of these were rebadged by Graflex as the Century 35 series.
In 1960, Kowa inaugurated a series of amateur 35mm SLR cameras, all with a leaf shutter. The last of the series was the Kowa UW190 (1972), equipped with a fixed ultra-wide-angle 19mm lens. In 1968, the company introduced a more ambitious project: the Kowa Six 6×6cm SLR, which would meet some success as the poor man's Hasselblad. It was upgraded in 1974 as the Kowa Super 66, which was Kowa's last camera in the century.
In 2005, Kowa, which had continued to sell equipment for birdwatchers and others, marketed a "spotting scope" with integrated digital camera, thereby again becoming a name on a camera. The product was the TD-1. In early 2009 the company described this as discontinued but still in stock; Kowa was marketing a variety of adapters to mate its spotting scopes with cameras from other manufacturers.

- Kowa lenses in Miranda mount:
The Prominar 7.5cm f/3.5 and 7.3cm f/3.5 lenses in Leica screw mount are not marked as made by Kowa. They are similar to the Sun Sola 7.5cm and 7.3cm f/3.5, and were certainly manufactured by Sun or its predecessor. They were perhaps produced before the name was registered by Kowa, or renamed because of a trademark conflict.
