An aerialphoto-mosaic of 1/3,000, made in 1937, was discovered in Karuizawa, Nagano prefecture. It was presumably a partial area of regional urban planning maps, and the first finding in townvillage autonomy in Japan. It shows the aerial photogrammetry had been already usual in 1937 rather than special high technology for the urban area. The mosaic was produced by Nippon Kuchusagyo joint-stock company established in 1929, the predecessor of Asahi Koku-kogyo Co. Ltd. It was 7 years earlier than the supposed history of private aero-survey companies in Japan. The monophotogrammetry of the year of 1935's had been already the great innovative technology for the urban planning, etc. which needs large scale maps, although to have been thought to develop just after the World War II.
