General Information
Okuyama Boring Co., Ltd. is a specialized geotechnical engineering firm headquartered in Yokote-City, Akita Prefecture, Japan. Established in 1946, the company possesses over 75 years of experience in addressing complex landslide-related challenges and providing integrated solutions to reduce landslide risks. Guided by the corporate slogan, “Create the world abundant and prosperous for future,” Okuyama Boring Co., Ltd. aims to create new value to meet society’s evolving needs and contribute to the development of safe and resilient social infrastructure.
Business Sector
The company primarily operates within geotechnical investigation, design consulting, slope engineering construction, and software research and development. Okuyama Boring Co., Ltd.’s core business areas encompass comprehensive geological and soil surveying, landslide monitoring and analysis, the design and implementation of landslide countermeasure works, and the development of proprietary numerical simulation software for sediment behavior.
Application
Okuyama Boring Co., Ltd.’s technologies and services are applied extensively in disaster prevention projects and social infrastructure development. Their integrated solutions are utilized to detect early signs of slope failures, assess slope stability, predict the behavior and runout distances of debris flows, and support disaster risk assessment and early warning systems. Furthermore, their practical engineering applications—such as drainage systems, ground reinforcement, and retaining structures—are implemented to mitigate landslide risks, protect local communities, and ensure the long-term safety of infrastructure.
