Investigation is possible even in narrow sea areas and shallow waters! We also introduce multi-channel shallow reflection methods that allow for deep investigations!
At Kyoa Development, we conduct "acoustic wave exploration," which allows for detailed investigations and deep surveys by changing the sound source and frequency. By emitting sound waves towards the seabed and observing reflections at acoustic impedance boundaries, we can understand the geological structure beneath the sea surface. We consistently carry out everything from measurement to analysis in-house, providing rapid and highly accurate exploration results. 【Features】 ■ Detailed investigations and deep surveys are possible by changing the sound source and frequency. ■ A wide range of surveys offered: - Investigation of burial conditions in ports and shipping routes using parametric acoustic wave exploration. - Surveys of active faults in coastal areas and other shallow marine investigations. - Geological structure surveys at depths of several hundred meters using boomer and sparker technologies. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Koa Development was established in 1953 (Showa 28), and thanks to your support, we have surpassed our 60th anniversary, for which we are sincerely grateful. Our company started as a geological survey firm and now primarily focuses on consulting services related to ground and groundwater, as well as soil environment consulting and purification and restoration projects to maintain a rich global environment. In our country, natural disasters caused by earthquakes, heavy rains, and typhoons, such as the Great East Japan Earthquake and the Hiroshima heavy rain disaster, are frequent. This is exacerbated by Japan's unique vulnerable ground and steep terrain, which amplify the scale of disasters. In such a natural environment, the role our company plays as a group of ground experts (Geo-Doctors) is becoming increasingly important. We aim to further refine the ground and soil environment-related technologies that form the foundation for the development of social infrastructure and the construction of a sustainable society, providing optimal solutions and contributing to society so that everyone can live safely and securely. We will continue to prioritize our customers and strive for further development of our business, so we kindly ask for your guidance and encouragement.
