"空中庭園" (Kūchū Teien), or "Sky Garden," refers to a type of garden that is elevated above ground level, often found on rooftops or terraces. These gardens are designed to provide green spaces in urban areas, promoting biodiversity and improving air quality. They can include a variety of plants, flowers, and sometimes even small trees, creating a serene environment amidst the hustle and bustle of city life. In cities like 大阪 (Osaka) and 東京 (Tokyo), sky gardens are popular for their aesthetic appeal and recreational opportunities. They often feature seating areas, walking paths, and sometimes even cafes, allowing people to enjoy nature without leaving the city. These gardens contribute to sustainable urban development by utilizing otherwise unused spaces.
