Miyata Manufacturing Co., Ltd. (Ota Ward, Tokyo)
In business in various forms since 1890, Miyata Manufacturing initially produced the Asahi (アサヒ号) line of British styled motorcycles. The first version was based on a Triumph in 1913, and at least one was supplied to the Tokyo Metropolitan Police Department in 1914 (reference https://ja.wikipedia.org/wiki/モリタ宮田工業). Motorcycle production stopped in 1916 and then resumed in 1933 with the introduction of a 175cc two stroke called the Asahi A. Post war production resumed in 1949 with the Asahi DC and motorcycle production continued till 1959 when they became controlled by Panasonic. The Asahi line were both two stroke machines of 200cc displacement and lower, and four stroke s.v. and o.h.v. machines typically of 249cc. The largest peace time displacement machine offered was the 1956 350cc JA.
They then produced scooters from 1959 through till 1964 sold under the Miyapet (ミヤペット号) name, which were sold domestially, but were also exported. Mike has provided me a copy of an ad from the UK. The company now manufactures fire safety equipment.
