Shocking footage! Please watch the soil dispersion experiment video. Click the related links below. 【The Rooftop Greening Revolution Begins】 Recently, phenomena that were once called abnormal weather, such as heavy rain and strong winds, have started to become normal. The plants used in the thin-layer rooftop greening so far have mainly 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 only specialized contractors could manage. The rooftop greening revolution aims to break 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 need for irrigation The Evergreen Sedum Bag Method is a new greening approach that puts soil specifically 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 across 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 is there an increase in temperatures, but extreme cold during winter has also been noted as one of the abnormal weather patterns in recent years. Amidst this increase in such weather phenomena, various problems have arisen in rooftop greening as well.

Soil Erosion Experiment One of the reasons for the failure of rooftop greening is "soil erosion." We recreated heavy rain by bursting large water balloons and conducted an erosion experiment comparing the "bag method vs. conventional method" of rooftop greening systems. Recently, extreme weather has increased, and the amount of rainfall exceeding 80 mm per hour, referred to as "intense rain," has increased by about 1.7 times in the last 30 years. Such heavy rain can wash away the soil and plants of rooftop greening, causing issues like 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 windbreak 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 tourist information corner. The top floor, the eighth 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 throughout the rooftop greening. This cannot be accommodated by conventional tray-based greening. The Evergreen Kirinsou Bag Method also adapts to square sizes of 50cm, 25cm, and rectangular sizes of 15cm x 50cm. The Evergreen Kirinsou Bag Method has flexibility in the bags, allowing for shape modifications on-site. Additionally, custom sizes can be ordered, enabling 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" Construction Case: Slope Greening A sediment control dam, known as "sabouentai" in Japanese, is a type of dam installed in rivers. It is also referred to as a "sediment control dam." This facility captures harmful sediment such as debris flows that flow down from upstream and gradually releases the accumulated sediment, thereby regulating the amount of sediment flowing downstream. 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 sediment control dams has been difficult, and maintaining such 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, so it does not grow wildly, and the shape of the letters remains unchanged. The bag method is made from weed prevention sheets, effectively preventing weed intrusion and soil erosion. With such low-maintenance plants and the bag method, it becomes possible to create letters using this 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, leading to "co-creation" and "hope." In April 2007, at an exhibition, a project team was born. They wanted to create new solutions originating from the field to solve customers' problems. Three professionals who shared such passionate thoughts met, and the Evergreen Kiri-Sou Promotion Association was established. Professionals in plants, architecture, civil engineering, and facilities breathe new life into the city. Moments of inspiration are continuous. The opportunities to experience moments where the heartbeat never stops are becoming fewer. Why is that? Perhaps it is because of the increase in fakes and deceptions. We aim to remain professionals involved in plants, architecture, civil engineering, and facilities, 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.
