When Oda Nobunaga constructed Azuchi-Momoyama Castle in 1578, he invited the priest Oyo Meikan, who had resided at Jogonbo Temple and whose virtue Nobunaga had long respected, to his new castle town and constructed a temple in the ruins site of Jionji Temple, which used to be the family temple of the Sasaki clan, governor of Omi province, and Nobunaga named the new temple Jogonin Temple.

In 1579, the Azuchi religious debate took place between monks of the Nichiren and Jodo sects of Buddhism, at this temple. Nobunaga used this debate as a good opportunity to weaken the power of influence held by the Nichiren sect. The debate ended with the defeat of the Nichiren sect, which lost its powewr since then. Delighted with their victory, the monks of the Jodo sect chanted Kachidoki-nenbutsu (nenbutsu for victory), which has been dedicated to Buddha in November every year.

The stately main hall was what used to be the main hall of Koryuji Temple in Omihachiman City. It was dismantled and rebuild here. The Romon gate in Irimoya-zukuri style stands since the days of old Jionji Temple. These two structures and five pieces of the temple’s treasure are nationally designated as Important Cultural Properties, which include the wooden statue of sitting Amida Buddha, the pagoda-shaped sarira container housed in Zushi (a miniature Buddhist shrine), the silver statue of standing Amida Buddha housed in Zushi, the depicted image of Sanno Gongen in the Kenpon-Chakushoku style (silk-based colored picture) and Amida Shoju Raigozu (Amitabha mandala) in the Kenpon-Chakushoku style.
