Company information
In manufacturing, there are people, and in projects, there is drama. The "passion" of three individuals transcends the boundaries of the company to create "co-creation" and "hope." In April 2007, at an exhibition, a certain project team was born. They wanted to create new solutions originating from the field to solve customer problems. Three professionals who shared such a passionate desire met, leading to the establishment of the Evergreen Kiri-Sou Promotion Association. Professionals in plants, architecture, civil engineering, and equipment breathe new life into the city. A series of moving moments. The opportunities to experience moments where the heartbeat never stops are becoming fewer. Why is that? Perhaps it is because the number of fakes and forgeries has increased. We aim to continue being professionals involved in plants, architecture, civil engineering, and equipment, and we operate the Evergreen Kiri-Sou Promotion Association. The professionals have developed new greening methods and greening systems. That is the Evergreen Kiri-Sou bag method.
