The branch, also called the Chinzei Doctrine (é®西義), is one of the two largest branches of Jà Âdo-shà « Buddhism (the second being Seizan). The tradition traces itself to Benchà  (a.k.a. Shà Âkà  Shà Ânin), a disciple of Hà Ânen, but it was formally established as a separate branch by Benchà Â's disciple Ryà Âchà « (è¯忠, 1199âÂÂ1287). It is also sometimes called the Chikushi school due to its early development in the Chikushi region of Kyushu. It played a key role in shaping the doctrinal and institutional framework of Jà Âdo-shà «, which remains one of Japan's major Buddhist traditions today.
Originally based in Kyushu where Benchà  had been exiled, the sect contended with other disciples of Hà Ânen 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 Benchà Â.
The famous temple of Chion-in, Hà Ânen's gravesite, and the temple of Zà Âjà Â-ji in Tokyo are all administered by the Chinzei branch.
The Chinzei-ha (é®西æµÂ) emerged during the Kamakura period as one of several lineages that developed within Hà ÂnenâÂÂs Pure Land movement. It is mentioned in historical texts such as the Shijà « Hyakuen'en-shà « (1257), which classified Hà ÂnenâÂÂs disciples into distinct doctrinal factions. Among these, the teachings of Shà Âkà Âbà  Benchà  (1162âÂÂ1238) were recognized as the foundation of what became the Chinzei-ha.
The name "Chinzei" derives from Shà Âkà ÂâÂÂs missionary activities in the Chikushi region (modern-day Fukuoka Prefecture), where he established Zendà Â-ji as a major center for Pure Land practice. His influence extended across Kyushu and beyond, leading to the formalization of the Chinzei-ha as an orthodox lineage of Jà Âdo-shà «. Shà Âkà  was originally a Tendai monk, became one of Hà ÂnenâÂÂs closest disciples after encountering him in Kyoto. He was entrusted with a copy of Hà ÂnenâÂÂs seminal work, Collection on the Selection of the Nembutsu (Senchakushà «), and later propagated Pure Land teachings across western Japan.
Shà Âkà ÂâÂÂs writings sought to clarify doctrinal disputes within the nascent Pure Land community and reinforce the authenticity of Hà ÂnenâÂÂs teachings. His doctrinal approach became known as the Unifying One-Act Samadhi (Kekkai Ichigyà  Zanmai), which integrated key elements of Pure Land belief into a coherent system centered on faith and practice. Shà Âkà Âbà  was also known as a strong supporter of the tanengi doctrine ("many calling", which emphasized the need to recite nenbutsu as much as possible) and he criticized the supporters of ichinengi (once calling) teaching. He also advocated a balanced practice that included nembutsu and auxiliary Pure Land practices. Benchà  categorized Buddhist practices as either a general form of nembutsu (sà  no nembutsu) or the specific practice of reciting AmidaâÂÂs name (betsu no nembutsu), arguing that the latter ultimately encompasses all other Buddhist practices. Drawing from the Daichidoron, he wrote extensively to systematize Hà ÂnenâÂÂs teachings, notably in Matsudai Nembutsu Jushuin and Tetsu Senchakushà «.
A pivotal successor to Shà Âkà  was Ryà Âchà « (è¯忠, 1199âÂÂ1287) also known as NenâÂÂamidabutsu or NenâÂÂa. He expanded the Chinzei-haâÂÂs influence into eastern Japan, particularly in Kamakura and the Kantà  region. Ryà Âchà «âÂÂs missionary work helped establish the Chinzei-ha as one of the largest mainstream lineages of Jà Âdo-shà «.
Ryà Âchà «'s efforts gained the patronage of Hà Âjà  Tsunetoki, the fourth regent of the Kamakura shogunate, as well as other influential members of the Hà Âjà  clan. In 1243, he established Goshin-ji temple in Kamakura, which was later renamed Renge-ji and eventually Kà Âmyà Â-ji. This temple became a key center for the propagation of Pure Land teachings, and Ryà Âchà « continued to garner support from other shogunate officials, solidifying his role in the development of the Jà Âdo school. He was so influential that he became known as the third patriarch of the school.
Ryà Âchà « also systematized the schoolâÂÂs teachings through texts like Jà Âdo-shà « Yà Âshà « and Ketsugi-shà Â, which further refined the role of the Five Gates of Mindfulness (äºÂéÂÂ念æ³Â) and the Three Minds (ä¸Âå¿Â) in Pure Land practice, seeing them also as paths to the Pure Land. His teachings emphasized the power of the nembutsu to eliminate bad karma and how the greater a person's evil karma, the greater the amount of nembutsu practice was needed.
After Ryà Âchà «'s passing, his disciples divided the Chinzei sect into six sub-branches, though they all preserved his teachings on practice. In the Muromachi period (1336âÂÂ1573), the main Chinzei-ha sub-lineages were:
These branches contributed to the spread of Jà Âdo-shà « throughout Japan, particularly in Kyoto and Kanto.
One later figure who was pivotal in the development of the tradition was Shà Âgei (èÂÂå 1341-1420) of the Shirahata lineage. It was Shà Âgei who established a formal independent system for training Jà Âdo-shà « priests (previously Jodo priests had to train under Tendai or Shingon lineages). Before this, Jà Âdo-shà « were not formally independent from Tendai, since they relied on Tendai for their training and ordination. Shà Âgei also promoted the recitation of the nembutsu in front of Shinto kami shrines, seeing the kami as manifestations of Amida Buddha.
Shà Âgei is considered the eighth patriarch of Jà Âdo-shà « Chinzei-ha and as a leader to made the school fully independent, establishing master-disciple lineage of priestly ordination which also included the bodhisattva precepts. This formal ordination was based on the Bodhisattva Precept Ceremony (Ju bosatsu kaigi æÂÂè©è©æÂÂå which the school had received from the Tendai tradition. This element sharply contrasts the Jà Âdo-shà « with the Shinshà « tradition who set aside all precepts and developed its own tradition of ordination.
Due to influence of Shà Âgei, the Shirahata-ha sub-sect of Chinzei-ha ultimately became the dominant force within the tradition.
A major event during this was the Chinzei sect's absorption of Chion'in temple, a major temple in Kyoto that had evolved out of Hà Ânen's gravesite. The heads of this temple had traditionally been closer to the Seizan sect. However, in 1450, Shà Âgei's disciple Keijiku (1403-59) was named head priest of Chion'in with the backing of emperor Gohanazono. Since that time, Chion'in was a Chinzei temple, giving the sect the prestige and aura of being the caretaker of the grave of Hà Ânen.
During the Edo period, the Chinzei-ha flourished under the patronage of the Tokugawa shogunate (1603âÂÂ1868). Key figures such as SonâÂÂà  of Zà Âjà Â-ji and Sonshà  of Chion-in played instrumental roles in formalizing the structure of Jà Âdo-shà « temples and doctrine. However, with the implementation of the temple registration system (danka-seido), the school also faced challenges in maintaining its doctrinal purity.
The Meiji Restoration brought significant reforms to Buddhism, leading to a decline in institutional power. In response, modern scholars like Fukuda Gyà Âkai sought to adapt Chinzei-ha teachings to contemporary society, ensuring their continued relevance within Jà Âdo-shà «.
