Japan shopping mall rooftop greenery plan

Quick answer：

Rooftop greenery in shopping malls in Japan refers to the practice of covering the roofs of these buildings with vegetation. This is done for several reasons, including reducing the urban heat island effect, improving air quality, and providing aesthetic benefits. The plan typically includes selecting suitable plant species that can withstand the specific conditions of the rooftop, such as limited space, wind, and exposure to direct sunlight. It also involves careful planning of irrigation systems and soil management to ensure the health and longevity of the plants.
