This camera is about the standard size and weight for a fixed-lens Japanese rangefinder camera of the period. it measures 130 x 60 x 80 mm and weighs xxxg. Of the three Japanese rangefinders I own, this is the most thoughtfully designed.
The viewfinder has bright-lines and the display for the light meter. There are no parallax markings for close-ups as the viewfinder physically moves as you focus the lens. This is quite a sophisticated facility for a mid-range camera. The viewfinder also includes the word "END" when the frame counter reaches zero.
The rangefinder spot is yellow (as is usual) but is an undefined blob which makes using the rangefinder harder than it should be. Having said that, it does work in good light - test photos will tell me how well. Both the light meter and the rangefinder are coupled.

The back of the camera is very plain - just the viewfinder eyepiece and the film advance lever. Inside, film attachment is very simple and is about the easiest I have ever come across. There is a generously wide slot with a prominent tang to fit into a sprocket hole. Most 35mm cameras have a shaft with top and bottom sprocket wheels. Not here. There is a single large sprocket wheel below the film gate. This does nothing with the back open making it easy to secure the film to the take-up spool - the film advance will keep moving the film without the user having to repeatedly press the shutter release. Once the back is shut, this sprocket wheel will only allow one frame to advance at a time.

Test film results.The results are good. In the pictures, the horizontal bars to be seen in the sky in some pictures are a scanning artefact due to the negatives being a bit thin (i.e. under-exposed). Overall, both focus and exposure are as they should be producing usable negatives. Although not all the negatives have scanned well, they would produce reasonable silver -prints.
