Our company made a donation to the "Manhole Toilet Unit Development Project at Evacuation Centers," utilizing the corporate hometown tax system promoted by Isehara City, and we received a letter of appreciation from Mayor Tetsuya Hagiwara. Donation System: Isehara City Town, People, and Work Creation Donation Utilization Project (Corporate Hometown Tax) Target Project: "Protecting Lives" (Specific Project Name: Manhole Toilet Unit Development Project at Evacuation Centers) This project aims to improve sanitary conditions at evacuation centers during large-scale disasters by developing manhole toilet units utilizing sewer facilities, ensuring a safe and hygienic toilet environment even during emergencies. In Isehara City's earthquake countermeasure project for sewer facilities, efforts are being made to strengthen the seismic resistance of pipes from disaster prevention bases and evacuation centers to the final treatment plant. In this context, our technology, "Magma Rock Method NGJ/Magma Rock Method Mini NGJ," has been adopted since 2014, and the manhole toilet development project is highly compatible with our technology. As a company specializing in infrastructure maintenance, we will continue to contribute to the safety and security of the community.

On June 22, 2026 (Monday), our company gave a lecture in Professor Hiroshi Yamamura's "Water Environment Engineering" class at Chuo University, under the leadership of Chuo University and the general incorporated association Water-n.
