Dainenbutsu-ji Temple is located in Hirano Ward, Osaka City. It was founded in 1127 by the monk Ryōnin of Mount Hiei, at the request of the retired Emperor Toba. As the head temple of the Yūzū Nenbutsu sect, it is known as Japan’s first nenbutsu training hall, and its main hall is the largest wooden temple building in Osaka Prefecture. One teaching of the Yūzū Nenbutsu sect—closely aligned with modern concepts such as coexistence and mutual aid—holds that “one person’s nenbutsu connects to the nenbutsu of all, and the nenbutsu of self and others mutually interpenetrate to become a great power.” This teaching can be experienced during the Hyakumanben-e Ōjuzu-kuri (Great Prayer Bead Ritual), held on the 16th of January, May, and September each year. From May 1 to 5, the Manbu Oneri procession is performed: a child procession and joyous nenbutsu chanting and hymns enter the hall first; then, to the sound of gongs and guided by gagaku court music, twenty-five bodhisattvas proceed across the Raigō Bridge, followed by the principal image “Jūichi-son Tentoku Nyorai,” the head priest, and officiating monks. Afterward, participants pray with hands joined for the repose of their ancestors. This event was designated an Intangible Folk Cultural Property of Osaka in 2002.
