OYO Corporation

In 1951, Jun'ō Fukuda, an assistant at Hokkaido University, collected a vast number of ammonites to investigate the stratigraphy of the Upper Cretaceous layers spreading across the reservoir area of a planned dam site. The geological maps and cross-sections produced by Fukuda and colleagues caught the attention of dam planners, revealing their usefulness for site selection and design of the dam and the ore mountain.

In 1951, Atsuo Fukada, an assistant at Hokkaido University, collected an enormous amount of ammonite to investigate the stratigraphy of the upper Cretaceous layer, which extends into the flooded area of the planned dam site. Fukada's geologic maps and geologic sections caught the eyes of the people involved in dam construction. They were found to be very useful for determining the location and design of dam sites and quarry sites. This led to the establishment of the Fukada Geological Research Institute, the predecessor of OYO Corporation.
