石山本願寺
Over the next several decades, the Yamashina Mido remained the central headquarters of the sect, even as the Ishiyama Hongan-ji and the city of Osaka grew in size and prominence. In the 1530s, the Ikkō-ikki began to undertake attacks on major religious centers in the cities as other bands of Ikkō mobs had done against samurai rulers in the provinces. The mobs attacked the Nichiren Kenpon-ji in Sakai, the Kōfuku-ji and Kasuga shrines in Nara, among other sites, and incurred the ire of both clergy and lay adherents to Nichiren and other sects.
