Ishiyama Hongan-ji

1533 CE – 1580 CE · capital Ishiyama (Osaka)

The fortified headquarters of the True Pure Land Buddhist sect at Osaka, which withstood Oda Nobunaga for ten years before surrendering in 1580.

Origins

After its temple at Yamashina near Kyoto was burned by rival forces in 1532, the leadership of the Hongan-ji moved in 1533 to Ishiyama, a site on high ground at the mouth of the Yodo river, where a temple had been founded by Rennyo.

Rule and society

Under the head priests Shonyo and Kennyo, Ishiyama became a moated fortress and temple town, supported by donations from believers across Japan and by the Ikko leagues that controlled provinces such as Kaga. The abbot acted as a great lord, negotiating with warlords and the court, and the surrounding town grew into a commercial centre.

Decline and legacy

From 1570 Kennyo fought Oda Nobunaga, supplied by sea by the Mori navy until Nobunaga's iron-clad ships cut the route in 1578. Mediated by the emperor, Kennyo surrendered in 1580. Hideyoshi built Osaka Castle on the site, and the Hongan-ji later split into two branches.
