Kyoritsu Automobile Industry Co., Ltd., Hamamatsu City, 1953-55
Kyoritsu Automobile, founded in 1948, was originally in the automotive/motorcycle sales business, but in 1953 produced the 125cc Rush (ラッシュ号). Per the Hamamatsu City Cultural Heritage Digital Archive located at this link, it was a one year only make, but this appears to be incorrect. Kyoritsu Automobile used someone elses engine, but at this time the make is unknown, although if I were to guess, I'd say that it looks like a Tohatsu. Mike was kind enough to send me a couple of photos he scanned from the June 1955 Auto-By issue.
