Kasaoka Industry, Kasaoka City, Okayama Prefecture, 1953?
笠岡工業
Kasaoka Industry is listed in the Japanese language wikipedia site. It appears per the one source that I was able to find (Nakatansya), that they copied a Toyo Motor clip-on engine and labelled it as their own engine called the First Motor (ファーストモーター号). Other translations list it as being Fast Motor (ファスト・モータ号) but perhaps that is what the assembled machine with engine was called, or is just a transcription error. No doubt time will tell.
