Shocking footage! Please watch the soil runoff experiment video. Click the related links below. 【The Rooftop Greening Revolution Begins】 Recently, heavy rains and strong winds, which were once referred to as abnormal weather phenomena, are starting to become the norm. The plants used in the thin-layer rooftop greening until now have mainly been sedums, but they are declining due to the recent weather conditions. Additionally, soil is being washed away and weeds are proliferating due to heavy rains 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 Kiri-so Bag Method®." 【Features of the Evergreen Kiri-so Bag Method】 ■ Soil runoff prevention ■ Weed control ■ Easy greening ■ Low maintenance ■ No watering required The Evergreen Kiri-so Bag Method is a new greening approach that puts soil specifically for evergreen Kiri-so into bags, achieving "soil runoff prevention," "weed control," and "easy greening."

Causes of Rooftop Greening Failures: Abnormal Weather In Japan, there have been many occurrences of damage from typhoons, heavy rains, floods, and landslides in various regions. Additionally, in recent years, there have been widespread heatwaves. In the first place, Japan's temperatures have been rising year by year, with particularly abnormal high temperatures observed during the summer and autumn. Moreover, not only the rise in temperature but also extreme cold in winter has been seen as one of the abnormal weather patterns in recent years. Amidst the increase in such weather, 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 system "bag method vs. conventional method" by creating strong winds using a blower and a circulator. Recently, it is predicted that there is an increasing trend in the occurrence of very strong tropical cyclones with maximum wind speeds exceeding 45 m/s due to abnormal weather. 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 Won't Fail - "Evergreen Kirinsou Bag Method" Case Study: Roof Greening This is roof greening using the "Evergreen Kirinsou Bag Method," a rooftop greening system that won't fail. Since it is on the roof surface, it is secured with anti-dispersion nets. 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 8th floor, is a free observation terrace. Due to the aging of the existing building, which is over 50 years old, 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 Kirinsou Bag Method" that won't fail, please visit https://kirinsou.jp.

Rooftop Greening Revolution: A Failsafe Rooftop Greening System "Evergreen Kirinsou Bag Method" Case Study: Rooftop Greening (Accommodating Curves) This is a rooftop greening project of approximately 180 square meters using the failsafe 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. Conventional tray-style greening cannot accommodate this. The Evergreen Kirinsou Bag Method also adapts to 50cm square, 25cm square, and 15cm x 50cm rectangular sizes. Since the bags are flexible, they can be shaped on-site, allowing for customization to fit the rooftop. The flexibility of the bags also enables greening on curved surfaces.

Rooftop Greening Revolution: A Fail-Proof Rooftop Greening System "Evergreen Kiri Grass Bag Method" Construction Case: Slope Greening A sediment control dam, also known as a "sediment dam," is a type of dam installed in rivers. It is designed to catch harmful sediment flowing downstream from upstream sources, such as debris flows, and gradually release the accumulated sediment to regulate the amount flowing downstream. By trapping sediment in the sediment control dam, the slope of the river becomes gentler, preventing the riverbed and banks from being eroded, while also reducing 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 that greening has also been challenging. The Evergreen Kiri Grass 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" Construction Example: 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 new shoots around November, ensuring that it does not grow wildly and change 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 the 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.
