It appears to be a 15 clone. The story is that the US gave the plans for the Singer 15 to Japan after WWII, so that they could re-start their manufacturing base. As I understand it, it's almost/exact replica of the Singer 15 (I've never owned a 15 clone, so I'm speaking from hearsay). They came out will all sorts of good old American names.
It is not a left homing machine. Are you sure you want a left homing machine?
