The garden includes the oldest fountain in Japan, though it only dates back to the 19th century. Fueled by the difference in water level (height, topography) between the pool of water in which it is located, and the nearby Kasumigaike (Kasumi Pond, or more literally, Pond of Mist), the fountain reaches a height of roughly 3.5 meters. | The garden includes the oldest fountain in Japan, though it only dates back to the 19th century.
