Mitsubishi Heavy Industries
As with Fiji Heavy Industries, at the end of WWII Naka-Nippon Heavy Industries, which was renamed Mitsubishi, retooled their armament industry and amongst other efforts entered the scooter market. Their 'Silver Pigeon' (see this link on their web site) was a copy of an American 'Motor Glide' made by Salisbury Corporation, who have an owner's club web site which you can visit at this link. The first 'Silver Pigeon' produced in 1946 was the model C-10 and over the course of production both 2 stroke and 4 stroke engines in single and twin cylinder designs ranging from 112cc through to 210cc were used . It was a very successful product with about 460,000 sold all together. Scooter production was stopped in 1963 to allow Mitsubishi to focus on 4 wheeled vehicles, which they still produce today.
Model C-74, C-75, 76, 80 and up to the C-90 Silver Pigeons were actually exported to the USA (according to 'Japan's Motorcycle Wars" some 12,360 units in total) beginning in 1958 and sold through Montgomery Ward. There is a USA based owners club and resources site which you can visit at this link.
