Ishibaji (Stone Horse Temple) in Gokasho Ishibaji Town in Higashiomi City on the eastern side of Lake Biwa is a historic temple belonging to the Myoshinji school of the Rinzai sect. The principal object of worship is Juichimen Senju Kanzeon Bosatsu (Kannon with 11 faces and 1,000 arms). The temple is famous as the Horse Temple.

Legend has it that when Prince Shotoku visited this village in 594, his horse was turned into a stone and sank in the pond while he was away. Deeply impressed by this incident, Prince Shotoku built up a temple at this place. Beside the ruins of the Daimon gate at the foot the stone steps is the pond where the stone horse sank. You can see the horse back through the water.

The temple belonged to the Hosso Sect of Buddhism until the Middle Ages. As a temple of the Tendai sect, it fought with Oda Nobunaga in the Warring States period (1493-1573) and was burnt down by his forces. The temple was restored in 1644, as a temple of Rinzai Sect of Buddhism, by Zen monk Ungo.

The temple possesses a lot of cultural properties including the wooden plaques on which three kanji characters representing Ishibaji Temple were written by Prince Shotoku himself and the statue of Prince Shotoku on the horseback.
