Elega-sha (エレガ社) was a Japanese company at the end of the 1930s. Its name appears in a 1938 advertisement for the Semi Elega 4.5×6 folder and the Elega darkroom chemicals. In this advertisement, the address was a postal box in Osaka.
Elega accessories were offered for sale by the distributor by Doi Shōten as early as 1939. After the war, the Elegaflex, Elega-35, Elega enlarger and maybe other Elega items were distributed by Doi Shōten and later Nittō Shashin Yōhin from 1951 to 1954. Doi Shōten certainly bought the name Elega or the company Elega-sha at some early time, or Doi was perhaps the new name of Elega-sha.
