What is "chinzei"

The branch of Jōdo-shū Buddhism is the main branch that exists today, and was first established by Benchō a disciple of Hōnen, but formalized into a separate branch by Bencho's disciple Ryōchū. Originally based in Kyushu where Bencho had been exiled, the sect contended with other disciples of Honen until it emerged into the dominant branch today. Its origins in Kyushu are also the reason for the sect's name, as Chinzei was an older name for Kyushu and was adopted by Benchō. The famous temple of Chion-in, Honen's gravesite, and the temple of Zōjō-ji in Tokyo are both administered by the Chinzei branch.
