Located on the grounds of Daikakuji Temple, Osawa Pond is one of the oldest man-made ponds in Japan. It is said to have been modeled after Lake Dotei in China when Emperor Saga built his detached palace, Saga-in, in the early Heian period. The pond is approximately 1 km in circumference and is also called “garden lake.” At that time, it was a center of culture where boating and other activities were held. Tenjinjima, Kikugashima, and Teiko-ishi are located in the pond, and the landscape of these two islands and one stone is the foundation of the Saga Goryu school of ikebana. In particular, Kikugashima is regarded as the birthplace of ikebana, as Emperor Saga hand-folded chrysanthemums and placed them in a vase. Osawa Pond, together with Sarusawa Pond in Nara and Ishiyama-ji Temple in Shiga, is considered one of the three best places in Japan to view the moon, especially during the Mid-Autumn Moon Festival, when “Kangetsu no Yuubei” is held and attracts many visitors. The area around the pond is also dotted with Gomado, stone Buddha statues, and a maple tree road, offering a seasonal view. Today, Osawa Pond is designated as a national scenic beauty spot and is highly valued for its historical and cultural value.
