Daikaku-ji is a Shingon Buddhist temple in Ukyō-ku, a western ward in the city of Kyoto, Japan. The site was originally a residence of Emperor Saga, and later various emperors conducted their cloistered rule from here. The Saga Go-ryū school of ikebana has its headquarters in the temple. The artificial lake of the temple, Ōsawa Pond, is one of the oldest Japanese garden ponds to survive from the Heian period.
