Mission
The giant salamander, the world's largest amphibian, has lived since prehistoric times and is considered a "living fossil." In Japan, it is designated as a Special Natural Monument, and conservation efforts are actively underway. Tap or click to find the giant salamander living quietly in a river rich with biodiversity.
Catfish are widely found throughout the world, and in Japan they live in the middle to lower reaches of rivers, lakes, marshes and irrigation canals. Some catfish living overseas live longer than 50 years, with some exceeding 3 meters in length. Tap or click to find catfish that live in rivers flowing into dams.
Clownfish are tropical fish that love warm ocean waters. They inhabit tropical environments from the Pacific to the Indian Ocean. They live in symbiosis with sea anemones, both protecting each other from predators. Tap or click to find clownfish swimming in the rich and beautiful sea.

In recent years, abnormal weather conditions caused by climate change have resulted in disasters around the world. In Japan, typhoons and torrential rains cause flood damage every year.
To protect lives and livelihoods from flood damage, more river repairs are needed. Underwater construction, such as lowering the river bottom so large amounts of water can flow safely (river channel excavation), plays a major role in this effort. Underwater work also plays a major role in recovering from a major disaster.
We quickly remove sediment and obstructions (driftwood, debris, etc.) caused by earthquakes, floods and landslides. We also quickly restore coastal protection structures. Sediment that flows into a river from upstream and accumulates at the bottom of a dam reservoir can reduce the capacity of the reservoir and thwart the functions of hydropower facilities. Underwater construction robots are expected to play an active role in the removal of such sediment. Wind power generation is equipment that generates electricity by rotating wind turbines with the force of the wind.
Wind power generation can be roughly classified into onshore and offshore installations, but it is offshore wind power generation that is currently attracting the most attention around the world.
Underwater construction robots are expected to play an active role in the excavation of the seabed, cable burial, and maintenance during the construction of offshore wind power generation facilities. Blue carbon refers to carbon absorbed and stored in marine areas.
Carbon absorbed by living organisms on both land and in marine areas used to be called green carbon, but recently a distinction has been made between green carbon in terrestrial areas and blue carbon in marine areas.
Blue carbon is attracting attention because it is more effective at sequestering carbon. Underwater construction robots are expected to play an active role in the conservation and restoration of eelgrass beds and tidal flats, which are blue carbon ecosystems.

Future underwater construction:
Tackling social issues
Tackling social issues
Underwater construction plays a major role in many fields, such as disaster prevention and mitigation, disaster recovery and nature conservation. There are high expectations for its contribution to the clean energy field. Ultra-remote operation equipped with the latest automatic control and information and communication technology (ICT) functions enables safe and easy operation by anyone, revolutionizing the conventional underwater construction site.

In Japan, where the birthrate is declining and the population is aging, workforce shortages are a serious problem at construction sites.
There is also a concern that the technical skills of construction workers will decline as experienced craftsmen retire.
Underwater construction robots equipped with the latest automatic control and ICT functions can help solve these social issues.
Underwater construction robots are electrically driven and can carry out environmentally friendly underwater construction without carbon dioxide emissions. They can be operated safely and easily by remote control, revolutionizing the conventional underwater construction site.
