The Royal Junior is a Japanese 6×6 folding camera, attributed to Sanshin Sangyō. It is said to take both 6×6cm and 4.5×6cm exposures, to have both a folding optical finder and a brilliant finder, a fixed-focus Royal Rapid lens and a synchronized shutter (B, 25, 50, 75, 100). The camera was announced in the June 1951 issue of Asahi Camera and advertised in the February to June 1952 issues of Camera Fan.
No picture of the Royal Junior has been observed so far, and no surviving example is known yet.
