Welcome! What Cari said is right on. You have a painted machine so regular cleaners should be safe on it. Old black ones are japanned with a shellac clear coat. Those need to be treated much more carefully. Sewing machine oil is safe for all machines.
Take a look at the sticky here on cleaning machines and watch Muv's videos. Her machines are older but her methods are good for any sewing machine. Stay away from WD40 and 3-in-1 oils. Neither are suitable for sewing machines.
Can you take pictures of the treadle too and is this machine still electric or was it converted to be used as a treadle?
The Japanese manufacturers made a lot of different machines with a lot of different labels. If you go thru some of the threads here on Japanese machines you may find a similar machine with a different badge but basically the same. A lot of machines rolled out of the same factories with different badges and trim details but were basically the same under the surface.
