Ishiozan Koboji Temple is a temple of the Koyasan Shingon school of Buddhism located in Mancho, Izumi City, Osaka Prefecture. Its mountain name is Ishiozan, and it has long been affectionately known by local residents as “Ishio no Odaishi-san”, meaning “the Kobo Daishi of Ishio.”
The principal object of worship is Dainichi Nyorai (Mahavairocana Buddha), accompanied by statues of Jizo Bosatsu and Kobo Daishi. The temple is also home to a colorful standing statue known as Fukutoku Jizo, which has been cherished by generations of worshippers.
The temple grounds feature a variety of Buddhist statues and peaceful walking paths. Behind the main hall, on a hill known as Ogami-yama, stands a statue of Byakue Kannon, the White-robed Kannon. Along the path leading to the statue are stone Buddhist figures representing the 88 temples of the Shikoku Pilgrimage. Visitors can walk this miniature pilgrimage route while taking time for quiet prayer.
Koboji is said to have been founded during the Daido era (806–810), when Kukai, also known as Kobo Daishi, climbed Mount Makio and established a place for Buddhist practice.
During the Konin era (810–824), a local wealthy landowner known as Fusaya Chōja donated funds to construct a temple building. Dainichi Nyorai was enshrined as the principal object of worship, with Jizo Bosatsu placed alongside it. Since then, the temple has remained an important place of faith for the local community.
The name Ishiozan is traditionally said to have originated from a large stone buried in the mountain that was shaped like the tail of a wild animal.
The surrounding area is also home to several historic Buddhist temples, including Makiozan Temple, the fourth temple of the Saigoku Kannon Pilgrimage, and Matsuoji Temple, which was rebuilt by Toyotomi Hideyori. Together, these temples have traditionally been known as the “Three O” of Senshu and have long attracted religious pilgrims.
Two Nio guardian statues stand on either side of the entrance after passing through the temple gate. On the left is Agyo, whose mouth is open, while on the right is Ungyo, whose mouth is closed. Their powerful expressions are traditionally believed to ward off evil spirits.
The statues’ particularly strong-looking feet have also become associated with worship for healthy and strong feet. Many visitors touch the statues’ feet while praying for good fortune and protection.
Two charming statues known as “Kobon-san” stand in front of the temple gate. The statue on the left wears a different hat according to the season, giving it an especially endearing appearance.
The statue on the right is characterized by a large head symbolizing abundant wisdom and arms spread wide. Visitors gently rub its head while praying to receive wisdom.
The temple grounds feature stone monuments representing the Thirteen Buddhas, an important group of Buddhist figures in the Shingon tradition, as well as a mani wheel engraved with the Heart Sutra.
It is believed that turning the mani wheel once brings the same religious merit as reciting the Heart Sutra once. Visitors quietly turn the wheel while offering their prayers.
The grounds also feature a statue of Kobo Daishi engaged in Buddhist practice, representing the spirit of “Dōgyō Ninin,” or “two traveling together.”
This expression reflects the belief that Kobo Daishi is always traveling alongside and watching over pilgrims. Visitors are reminded of his presence as they offer their prayers at the temple.
The temple’s Boke-Yoke Jizo is believed to offer protection against memory loss and support healthy aging, attracting visitors who pray for mental well-being.
Jizo is traditionally believed to watch over people during the period between the death of Shakyamuni Buddha and the appearance of Maitreya Bodhisattva, who is expected to come into the world in the future to save living beings.
Inside the main hall are a colorful statue of Fukutoku Jizo and a statue known as Binzuru-san.
Fukutoku Jizo has long been worshipped as a Buddhist figure associated with good fortune and virtue, and visitors offer prayers for their wishes to be fulfilled.
Binzuru-san is traditionally believed to have healing powers. Visitors gently rub the corresponding part of the statue while praying for relief from ailments affecting the same part of their own body.
At the summit of Ogami-yama, behind the main hall, stands a statue of Byakue Kannon, the White-robed Kannon. From the hilltop, visitors can enjoy a panoramic view across the Senshu Plain.
The Kannon statue stands peacefully overlooking the landscape, symbolizing prayers for the happiness and well-being of those who visit. Benches are also provided at the summit, making it a pleasant place to rest while looking across the city of Izumi.
