The Oplen Junior[1] (オプレンジュニア) is a Japanese 6×6 camera, known from Kokusan kamera no rekishi, where it is attributed to the distributor Goyō Shōkai.[2]

The camera was featured in the new products column of the September 1955 issue of Sankei Camera.[3] It is described as a box camera made of bakelite. The film apparently runs horizontally, and its advance is controlled by red window. The viewfinder is a large brilliant finder, making the camera a pseudo TLR. The lens is an f/6.3 meniscus and the shutter has B and I (Bulb and Instant) settings. It is synchronized for a dedicated cordless flash unit, directly attached to the camera.

The Oplen Junior appears identical to the Palma Brilliant and Rosko Brilliant, which are attributed to Goyō by other sources.[4]
