OYO At a Glance

Large-scale seismic motion calculation / surveying for earthquake damage prediction

We provide various services that form the basis of disaster prevention strategies for national and local governments; for example, determining the epicenter of large-scale earthquakes, analyzing wide-area seismic motion, surveying for earthquake damage prediction, and supporting the formulation of regional disaster prevention plans and action plans.

3D geotechnical analysis technology / OYO GeoTools

By visualizing the inside of the ground in 3D, we eliminate problems such as construction accidents and defective construction caused by geotechnical problems and support the development of smart cities.

Pavement maintenance management services using traffic big data

This infrastructure DX solution efficiently and inexpensively diagnoses unevenness and cracks in roads by aggregating data (wheel behavior, rotation speed changes, etc.) that is constantly transmitted by connected cars via the internet.

Under-road cavity exploration services

These services use under-road cavity exploration vehicles equipped with ground penetrating radar and AI analysis to perform non-destructive and high-speed detection of dangerous cavities hidden under roads. This reduces construction risks caused by road sinkholes.

Cultural heritage conservation support services

By using geological survey technologies such as ground-penetrating radar, we provide a variety of services for the protection and conservation of cultural properties, including surveys, conservation measures, and utilization support for ruins and other structures.

Naturally derived heavy metals countermeasures services

These services survey and analyze earth and sand generated from excavation work, etc., which contain naturally derived heavy metals that adversely affect the environment and human health, and support appropriate processing and storage.

Soil / groundwater pollution surveys and countermeasure support services

We survey the pollution status of land contaminated by corporate business activities, etc., and provide consulting on necessary countermeasures and supervision for constructing countermeasures.

Hazard mapping sensor solutions (flood sensors)

These solutions use disaster prevention IoT sensors that detect flooding to ascertain the occurrence of river flooding and other disasters in real-time, and then promptly notify nearby residents and local government officials of danger.

Volcano monitoring system

By installing sensors at 47 active volcanoes throughout Japan and observing earthquakes, tremors, and crustal movements associated with volcanic activity, this system is used by the Japan Meteorological Agency for eruption warnings and forecasts.

Hazard mapping sensor solutions (tilt sensors)

These solutions use disaster prevention IoT sensors to detect the occurrence of landslides and other disasters in real-time, and then promptly notify nearby residents and local government officials of danger.

Watershed / flood control services

These services efficiently find weak points in long river embankments that may collapse during heavy rains, etc., and propose construction of appropriate countermeasures.

Tunnel inspection, maintenance, and management services

These services utilize technology such as the latest AI and 3D models to efficiently inspect long roads and railway tunnels, and support appropriate maintenance and management by customers, such as proposing repair and reinforcement measures.

Biodiversity surveys and OECM registration support services

We conduct biodiversity surveys and provide OECM registration support services that contribute to the achievement of 30by30* goals for companies that are actively engaged in environmental management.

* 30by30: A worldwide initiative to effectively protect and conserve at least 30% of Earth's land and ocean area as healthy ecosystems by 2030, with the goal of halting and reversing biodiversity loss. Committed by each country at the G7 Summit in June 2021.

*In order to achieve 30by30, this mechanism certifies regions that contribute to biodiversity conservation other than protected areas, such as company-owned forests and Satoyama landscape (traditional rural landscapes in Japan) as sites in harmony with nature.

Appropriate management system for invasive fish to protect water areas and fisheries

This is a low-density management service that systematically and efficiently exterminates invasive fish by combining the understanding of habitat species and population numbers using environmental DNA and the selective capture of non-native species by electrofishing boats.

Flood sensor bollards

This disaster-prevention IoT solution incorporates flood sensors into traffic bollards found on sidewalks and parks. When flooding is detected, an email notification is sent to administrators, etc., and the emergency lights turn on to warn people in the surrounding area of danger.

Offshore wind power generation support services

These services are for seabed geotechnical surveys for acquiring seabed data required for the basic design of wind turbines for offshore wind power generation. Our entire Group contributes to the decarbonization of society. Examples include cable route surveys related to offshore wind power generation provided by subsidiaries and the provision of mine detection equipment.

Tsunami height and flooding area prediction services

These services make full use of advanced calculations and simulations using supercomputers, etc., to predict tsunami heights and flooding areas over wide areas. These predictions form the basis of national and local government disaster prevention strategies and damage estimation surveys.

Disaster prevention support services for power facilities, etc.

These services contribute to the stable supply of energy in Japan through risk assessments of earthquakes and tsunamis at power plants, etc., and various ground surveys aimed at strengthening facilities.

Tree diagnosis

We use a special radar exploratory system for tree diagnosis to quickly investigate and diagnose conditions inside the trunk and rhizome without damaging the tree. This makes it possible to prevent damage to people and vehicles due to the collapse of roadside trees.

Underground visualization services

These services use 3D ground penetrating radar exploration vehicles and AI analysis to visualize and map accurate 3D location information of underground infrastructure under roads in urban areas, and then provide that information on demand. This prevents accidents such as damage to underground infrastructure during underground excavation work.
