OYO'S HISTORY

In 1957, OYO started as a geological survey company under the slogan of "Creating Geological Engineering". The slogan "Creating Geological Engineering" refers to our aim to create new markets by applying the scientific field of geology to the civil engineering and engineering fields, and by pioneering the border areas between the two fields.
Even now, we continue to value this frontier spirit from the time of our founding, and we are taking on the challenge of creating new markets through fusion with digital technology and cross-industrial open innovation.
