Tokiwa Kōgaku Kōgyō Y.K. (常盤光学工業有限会社) was a Japanese company based in Tokyo, Toshima, in the early 1940s.[1] (Tokiwa means "everlasting" or "evergreen", and it is also a fairly common family name in Japan.)
Camera maker
The company name Tokiwa Kōgaku Kōgyō appears in advertisements dated 1942 and 1943 for the Zeitax, a camera otherwise attributed to Motodori Kōgaku.[2] In the April 1943 government inquiry on Japanese cameras, Tokiwa Kōgaku Kōgyō and Motodori Kōgaku Kikai Kōgyō-sho are listed at the same address,[3] and there is obviously a relation between the two. (See also the Zeitax page.)
Lenses and shutters

Tokiwa Kōgaku supplied lenses and shutters to Kuribayashi. The following items are confirmed:
- Hit-Rapid shutter, T, B, 1–500 speeds (on the Baby Semi First, First Reflex and Semi Rotte);[4]
- First 75/2.9 lens, four elements (on the Semi First and First Six);[5]
- First 75/3.5 lens, three elements (on the Semi First, BB Semi First, First Six and Semi Rotte);[6]
- First 75/4.5 lens, three elements (on the Semi First, BB Semi First, First Six, Baby Semi First, BB Baby Semi First and Semi Rotte);[7]
- Rotte 60/3.5 lens, three elements (on the Molby);[8]
- Rotte 75/3.5 lens, three elements (on the BB Semi First)[9]
- Rotte 75/4.5 lens, probably three elements (on the BB Semi First, Baby Semi First and Semi Rotte);
- Tokiwa 75/3.5 lens, four elements (on the First Reflex II).[10]
The Hit 7.5cm f/3.5 four-element lens (mounted on the Auto Semi First and First Reflex II) was likely made by Tokiwa too, but this is unconfirmed.[11]
Other Tokiwa
Some recent sources say that the Tokiwa plate folders of the mid-1930s were made by Kuribayashi for Tokiwa Kōgaku,[12] but the name similarity is perhaps a mere coincidence.
It is unknown if Tokiwa Kōgaku was related with Tokiwa Seiki which made the First Six and Firstflex cameras distributed after 1945 by Minagawa Shōten (owner of the "First" brand). A company called K.K. Tokiwa Kōgaku (㈱ときわ光学) exists today (2007) but it was founded in 1956.[13]
