Jōdo Shinshū traditionally had an uneasy relationship with other Buddhist schools because it discouraged the majority of traditional Buddhist practices except for the nembutsu. Relations were particularly hostile between the Jōdo Shinshū and Nichiren Buddhism. On the other hand, newer Buddhist schools in Japan, such as Zen, tended to have a more positive relationship and occasionally shared practices, although this is still controversial. In popular lore, Rennyo, the 8th Head Priest of the Hongan-ji sect, was good friends with the famous Zen master Ikkyū.
