Failure-proof rooftop greening system "Evergreen Kirinsou Bag Method" construction example: Slope greening A sediment control dam, also known as a "sand control dam," is a type of dam installed in rivers. It is designed to catch harmful sediment, such as debris flows, that flows down from upstream and gradually release the accumulated sediment to regulate the amount of sediment flowing downstream. By accumulating sediment in the sediment control dam, the gradient of the river becomes gentler, preventing the riverbed and riverbanks from being eroded, while also weakening the destructive power of debris flows. Additionally, it helps stabilize the foot of the mountains on both banks and prevents landslides on the slopes. However, the construction of large concrete walls in mountainous areas can lead to landscape issues. Until now, greening on sediment control dams has been difficult, and maintaining the greenery has also been challenging. With the Evergreen Kirinsou Bag Method, greening has become easy. The greening of sediment control dams blends well with the surrounding scenery.

Evergreen Kirinsou Case Study: Solar Sharing + Greening Solar sharing refers to the initiative of installing solar panels on supports erected in agricultural land to regulate sunlight and share solar energy between agricultural production and electricity generation. The Ministry of Agriculture, Forestry and Fisheries refers to this power generation equipment as "agricultural-type power generation equipment." By effectively utilizing the upper space of agricultural land while continuing farming, it is possible to generate electricity, which supports agricultural management. Furthermore, it is also expected to contribute to the regeneration and reuse of increasing abandoned farmland. Evergreen Kirinsou is being produced under the solar panels. The evergreen Kirinsou cultivated here is actively used nationwide for rooftop greening, wall greening, and slope greening.

Fail-proof Rooftop Greening System "Evergreen Kiri Grass Bag Method" Case Study: Rooftop Greening (Renovation of Existing Greening) This is a renovation project for the existing rooftop greening on the 5th floor of a 10-story apartment building shaped like a "U" with a courtyard. The original rooftop greening was done with sedum, but it has become overgrown with weeds, causing issues. The request was to renovate while preserving the existing parts. The shape of the building resembles a pyramid, making it a challenging site for transporting materials. Since cranes could not be used, all materials were handled manually, and a temporary emergency hatch was utilized for material delivery. After removing the surface weeds, we treated the area to prevent weed germination. Subsequently, we laid down a weed barrier and performed greening using the Evergreen Kiri Grass Bag Method.

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.
