The Royal Junior (ローヤルジュニア) is a Japanese 6×6 folding camera, attributed to Sanshin Sangyō, probably the distributor. It is probably related to the Royal Senior and Royal 35, attributed to Royal Works or Royal Camera Works.
The Royal Junior is said to take both 6×6cm and 4.5×6cm exposures, to have 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.
