There appears to be an almost infinite variety of machines manufactured in Japan with various names, or "badges", on them, so finding a manual specific to this machine may be very difficult. Fortunately it does not appear to be a very complicated machine. The needle is likely a 15x1, which is pretty much standard now for domestic machines, and I agree with Janey, it looks to be a high shank machine. If there's a belt on it, you can measure its overall length and shop for a new one that way, or search this board (or the internet) for how to measure a sewing machine belt length.

If you need help with the controls, please post questions, and welcome to the QuiltingBoard.
