Introducing Our Business​

Solar Power

In October 2020, the Japanese government declared that it aims to achieve carbon neutrality by reducing all greenhouse gas emissions to net zero by 2050. Various companies are promoting the use of renewable energy sources in order to realize this goal of becoming carbon neutral by 2050. Among them, many companies, including those listed on the Prime market of the Tokyo Stock Exchange, have started powering their buildings and factories with solar power as a new energy source that can be used right away.


We provide dependable support for all essential solar power operations, from land arrangement, design, and construction to maintenance. By providing dependable support to a small number of elite clients, we are able to offer reasonably-priced, fast service.


Nanofibers excel at oil-water separation and are used to recover heavy oil in times of disaster. Taking advantage of these properties of nanofibers, we have developed and manufactured a user-friendly sheet called Oil Gather S01.


Nanofibers have the ability to absorb a number of substances other than oil. Please visit our dedicated website and feel free to contact us for more information.


We actively invest in the latest equipment such as aerial photography drones, drones equipped with laser scanners, GCPs, and thermal imaging drones.


For example, we use drones equipped with laser scanners to conduct ground surveys before installing solar panels. Advanced laser scanning allows for accurate topographic surveys, even in wooded areas.


In addition, thermal imaging drones can be used to check the heat generation conditions of solar panels. Utilizing the latest drone technology, we provide support based on accurate surveys from the planning stage to maintenance.
