Ishiba-ji, Buddhist temple in Higashiōmi, Japan.

Ishiba-ji is a Rinzai-shu Myoshin-ji temple at the foot of Mount Kinosasa in Higashiomi, Shiga Prefecture. Its main hall, the former Daito, was moved from the Iba Palace in 1634. The grounds also hold a karesansui garden called Ishiba no Sekitei, a bell tower, and the Ishiba Pond, where a stone said to be Prince Shotoku's petrified horse sits in the water.

The temple was founded in 594 after Prince Shotoku's horse transformed into stone and sank into a nearby pond during his visit. This legendary event marked the establishment of the sanctuary at this location.

The temple's name comes from the legend of Prince Shotoku's horse turning to stone; a stone horse is still visible in the lotus pond near the mountain gate site. Annual rites include Shusho-e on January 1, Nehan-e on February 15, Gotan-e on April 8, and Jizo-bon on a Saturday in late August. The temple is stop 36 on the Shotoku Taishi reijō pilgrimage and stop 69 on the Biwako 108 sacred sites route.

The temple stands at 823 Ishiba-ji Temple-cho, Gokosho, Higashiomi, on the southern slope of Mount Kinusa. From Notogawa Station on the JR Biwako Line, take the bus bound for Yokaichi Station and get off after about seven minutes. The stone gate foundations and the pond with the stone horse lie near the entrance, while the main hall and garden are further up the slope.

The temple keeps a wooden plaque inscribed "Ishiba-ji", said to be in Prince Shotoku's own hand, along with a statue of the prince on horseback at age 22. Near the site of the old gate, a pond holds the stone said to be the prince's horse, its back visible above the water.
