This temple belongs to the Tendai sect of Buddhism, the head temple of which is Enryaku-ji, on Mt. Hiei near Kyoto. The main hall of Rinno Temple, called the Sanbutsu-do, is the largest single building at Toshogu; it enshrines an image of Amida Nyorai, the Buddha of the Western Paradise, flanked on the right by Senju (Thousand-Armed) Kannon, the goddess of mercy, and on the left by Bato-Kannon, regarded as the protector of animals. These three images are lacquered in gold and date from the early part of the 17th century. The original Sanbutsu-do is said to have been built in 848 by the priest Ennin (794–864), also known as Jikaku-Daishi. The present building dates from 1648.
In the southwest corner of the Rinno Temple compound, behind the abbot's residence, is an especially fine Japanese garden called Shoyo-en, created in 1815 and thoughtfully designed to present a different perspective of its rocks, ponds, and flowering plants from every turn on its path. To the right of the entrance to the garden is the Homotsu-den (Treasure Hall) of Rinno Temple, a museum with a collection of some 6,000 works of lacquerware, painting, and Buddhist sculpture. The museum is rather small, and only a few of the pieces in the collection—many of them designated National Treasures and Important Cultural Properties—are on display at any given time.
