Shocking footage! Please watch the soil runoff experiment video. Click the related links below. 【The Rooftop Greening Revolution Begins】 Recent heavy rains and strong winds are starting to become normal phenomena that were once referred to as abnormal weather. The plants used in traditional thin-layer rooftop greening have primarily been sedums, but they are declining due to the recent weather conditions. Additionally, soil is being washed away and areas are becoming overrun with weeds due to heavy rain and strong winds. Until now, rooftop greening has involved many complex systems that could only be handled by specialized contractors. The rooftop greening revolution aims to break away from these existing methods and maintain a green oasis easily and sustainably. The system that has made this rooftop greening revolution possible is the fail-proof rooftop greening system "Evergreen Sedum Bag Method®." 【Features of the Evergreen Sedum Bag Method】 ■ Soil erosion prevention ■ Weed control ■ Easy greening ■ Low maintenance ■ No watering needed The Evergreen Sedum Bag Method is a new greening approach that puts specialized soil for evergreen sedum into bags, achieving "soil erosion prevention," "weed control," and "easy greening."

Causes of Rooftop Greening Failures: Abnormal Weather In Japan, there have been many instances of damage from typhoons, heavy rain, floods, and landslides in various regions. Additionally, in recent years, there have been widespread heatwaves. In fact, Japan's temperatures have been rising year by year, with particularly abnormal high temperatures observed during the summer and autumn. Furthermore, not only the rise in temperature but also extreme cold in winter has been noted as one of the abnormal weather patterns seen in recent years. Amidst the increase in such weather phenomena, various problems have arisen in rooftop greening as well.

Soil Dispersal Experiment One of the reasons for the failure of rooftop greening is "soil dispersal." We conducted a dispersal experiment comparing the rooftop greening systems "bag method vs. conventional method" by creating strong winds using a blower and a circulator. Recently, there has been an increase in abnormal weather, and it is predicted that the number of very strong tropical cyclones with maximum wind speeds exceeding 45 m/s over the sea (or ground) is on the rise. In such severe weather, the soil and plants from rooftop greening can be dispersed, causing problems such as clogging drainage systems.

Rooftop Greening Revolution: A Rooftop Greening System That Doesn't Fail - "Evergreen Kiri Grass Bag Method" Case Study: Roof Greening This is roof greening using the rooftop greening system "Evergreen Kiri Grass Bag Method," which does not fail. Since it is on the roof surface, it is secured with a scattering prevention net. The Asakusa Culture and Tourism Center is a tourist information facility located in Taito Ward, in front of the Kaminarimon Gate. The first floor features an information counter that supports Japanese, English, Korean, and Chinese, as well as a foreign currency exchange service, while the second floor has a tourism information corner. The top floor, the 8th floor, is a free observation terrace. Due to the existing building being over 50 years old and deteriorating, a competition was held in 2008, and the proposal by Kengo Kuma was adopted. The initial plan had a height of 41.25 meters, but voices of opposition arose from Senso-ji Temple and the local shopping district, claiming it would disrupt the harmony of the streetscape, leading to a reduction of about 2 meters, resulting in a height of 38.9 meters. In 2012, it received the Good Design Award. For more details on the Rooftop Greening Revolution and the "Evergreen Kiri Grass Bag Method" that doesn't fail, please visit https://kirinsou.jp.

Rooftop Greening Revolution: A Fail-Proof Rooftop Greening System "Evergreen Kirinsou Bag Method" Case Study: Rooftop Greening (Also Accommodating Curves) This is a rooftop greening project of approximately 180 square meters using the fail-proof rooftop greening system "Evergreen Kirinsou Bag Method." The greening area is divided into buildings A to D, and the shapes are not rectangular, with curved sections present throughout the rooftop greening. This cannot be accommodated by conventional tray-style greening. The Evergreen Kirinsou Bag Method has been adapted using square bags of 50cm, 25cm, and rectangular bags of 15cm x 50cm. The Evergreen Kirinsou Bag Method allows for flexibility in the bags, enabling shape adjustments on-site. Additionally, custom sizes can be ordered, allowing for rooftop greening tailored to the site. The bags are flexible, making it possible to green curved surfaces as well.

Rooftop Greening Revolution: A Fail-Proof Rooftop Greening System "Evergreen Kirinsou Bag Method" Case Study: Slope Greening A sediment control dam, known as a "sabouentai," is a type of dam installed in rivers. It is also referred to as a "sediment control dam." This facility receives harmful sediment such as debris flows that flow down from upstream and regulates the amount of sediment flowing downstream by gradually releasing the accumulated sediment. By accumulating sediment in the sediment control dam, the slope 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 foothills on both sides, preventing landslides on the mountain slopes. However, the construction of large concrete walls in mountainous areas can lead to landscape issues. Until now, greening has been difficult on sediment control dams, and maintaining the greenery has also been challenging. The Evergreen Kirinsou Bag Method has made it possible to easily green these areas. The greening of sediment control dams blends well with the surrounding scenery.

Rooftop Greening Revolution: A Fail-Proof Rooftop Greening System "Evergreen Kiri Grass Bag Method" Case Study: Slope Greening Using the Evergreen Kiri Grass Bag Method, we implemented greening with letters as a landmark for the interchange. Evergreen Kiri Grass is resilient to heat, cold, and drought, making it a low-maintenance plant. It replaces its new shoots around November, ensuring that it does not grow wildly and alter the shape of the letters. The bag method is made from weed control sheets, effectively preventing weed intrusion and soil erosion. With this combination of low-maintenance plants and the bag method, it is possible to create such lettering through a greening system.

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.
