The park was established on the site where Emperor Showa maintained a summer residence.
The garden's pond was intentionally shaped like the character 'kokoro' (heart).
The Museum of Nature and History within the park holds collections reflecting the Emperor's biological studies.
The garden integrates 'shakkei' (borrowed scenery) techniques using the nearby mountains as a backdrop.
The park maintains a distinct collection of Japanese black pine trees original to the coastal geography.
Hayama Shiosai Park is a Japanese-style garden constructed on the former site of the Hayama Imperial Villa. The grounds feature a pond designed to resemble the shape of the kanji for heart, surrounded by pine trees and diverse seasonal flora. The garden incorporates the natural topography of the Hayama coastline, offering views of the surrounding mountains and nearby Sagami Bay. Visitors can observe a small waterfall and a traditional stone lantern garden within the park landscape. The site also houses the Museum of Nature and History of Hayama, which displays artifacts related to the Imperial family's interest in marine biology. The park grounds provide a tranquil setting that emphasizes the aesthetic principles of traditional Japanese landscape design.
