Shinsen-en, Japanese garden in Nakagyō-ku, Japan

Shinsen-en is a Buddhist temple and Japanese garden in Nakagyō Ward, Kyoto. Its central pond, Hōjōchi-ike, is bordered by low dark stone edging and reflects the surrounding trees and buildings. A stone torii gate stands near the bank, and a traditional pleasure boat with an illuminated cabin floats on the water.

The site was created in 794 as an imperial garden for the Heian Palace and covered about 33 acres at that time. After centuries of change and gradual reduction, the garden was rebuilt in 1607 as a temple of the Shingon school.

The garden's pond is home to the dragon deity Zennyo Ryūō, said to have been summoned from a lake in India by the monk Kūkai in 824 to end a drought. The Zennyo Ryūō Shrine, with its hall, worship hall and middle gate rebuilt in 1813, stands in the grounds. Each 31 December the Ebisu shrine's deity is turned to face the coming year's auspicious direction.

The grounds lie south of Nijō Castle in central Kyoto and are easy to reach on foot. The garden is open to visitors, while some temple areas are accessible only at certain times.

The claim that Oike Dori takes its name from the pond is unconfirmed: no record shows the pond was ever called "Oike", and some scholars doubt it. A stone marker south of Nijo Castle, found during subway construction, shows the garden's former eastern edge. Kyoto Shimbun titled its wartime front-page column "Shinsen".
