Rennyo: The Religious Revolutionary Who Rebuilt Honganji into Japan's Most Powerful Sect
Rennyo (1415–1499), the eighth head of Honganji, found a decayed institution and transformed it into the most powerful religious force in Warring States Japan. Using the revolutionary *ofumi* letters written in simple Japanese, building a religious city of 100,000 believers at Yoshizaki, and establishing the template for the later Ikko-Ikki uprisings, Rennyo is rightly called the second founder of Jodo Shinshu.

“Trust in Amida and you shall be reborn in the Pure Land.” Rennyo (1415–1499) packed this single liberating certainty into plain-language letters called ofumi and delivered it to commoners across Japan’s Warring States period. Taking over a decayed Honganji at age 43, he gathered 100,000 believers at Yoshizaki, rebuilt the institution at Yamashina, and transformed Jodo Shinshu into Japan’s largest religious force. His revolution seeded the Ikko-Ikki uprisings, the Battle of Ishiyama, and the East-West Honganji split that followed.
Born into Decline — Poverty and the Loss of His Mother at Age 6
A Small Mausoleum, a Hungry Winter
Rennyo was born in 1415 as the first son of Sonyo, the seventh head of the Honganji. Two centuries after Shinran, the Honganji had declined to a small mausoleum in Kyoto’s Higashiyama, its grounds overgrown, its occupants barely fed. Rennyo later recalled spending winters with only one robe. When he was six, his mother left the world — taking religious vows and vanishing from his life. This early poverty and loneliness gave him the temperament to understand the pain of ordinary people.
A Forty-Three-Year-Old’s Late Inheritance
Though the eldest son, disputes and institutional turmoil delayed Rennyo’s succession until 1457, when he was 43. Eight years later, in 1465, warrior monks from Enryakuji (Mount Hiei) attacked and destroyed the Otani mausoleum in what became known as the Kancho Persecution. Rennyo was forced into years of fugitive movement across the provinces.
The Ofumi Letters — Medieval Japan’s Media Revolution
Words That Reached People Who Couldn’t Read
Rennyo’s first revolutionary act upon succeeding was to write the ofumi — letters in simple kana-mixed Japanese explaining the faith in plain, accessible language. “Trust in Amida and you shall be reborn” — the liberating certainty that one need not read difficult sutras to be saved, expressed in words that farmers, women, and the illiterate could understand.
The ofumi spread explosively through hand-copied manuscripts, read aloud at regional prayer halls to people who couldn’t read themselves. It was, essentially, medieval Japan’s media revolution.

The Miracle of Yoshizaki Gobo — 100,000 Believers
Moving to Echizen and Explosive Growth
In 1471, Rennyo built the Yoshizaki Gobo on a hill in Echizen Province (present-day Awara City, Fukui). The Hokuriku region had long been fertile ground for nembutsu practice, and the ofumi spread instantly. Believers poured in from Kaga, Echizen, Etchu, and Noto, and within a few years a religious city of 100,000 scale had appeared. Lodging halls lined the roads, markets opened, and the Honganji became the center of what was essentially a self-governing believers’ community. The Yoshizaki Gobo site in Fukui preserves this memory today.
Withdrawal from Yoshizaki
Yoshizaki’s prosperity generated friction with the local lord Asakura clan, and in 1475 Rennyo voluntarily withdrew. What appeared to be a retreat had in fact been a massive organizational seeding operation — the networks built at Yoshizaki underpinned the Honganji’s explosive growth in subsequent decades.
Rebuilding at Yamashina Honganji
Architecture That a Court Noble Compared to a Buddhist Paradise
Moving through Kawachi and Settsu, Rennyo built Yamashina Honganji in Kyoto’s Yamashina in 1483. Its magnificent halls and moat-encircled temple town prompted court noble Konoe Masaie to write in his diary: “Its grandeur is as if a realm of the Buddhas.” Here the Honganji was formally reestablished and confirmed as Japan’s largest religious organization.
The Complex Relationship with the Ikko-Ikki
Rennyo repeatedly preached “Oho-ho ibou” (respect the laws of the realm) — yet the powerful bonds of faith his ofumi had forged became, at times, the fuel of rebellion. In 1488 — thirteen years after he left Yoshizaki — Kaga believers overthrew the military governor Togashi Masachika and established the “country governed by peasants.” Rennyo did not advocate the uprising, but the faith communities he built were unquestionably its organizational and spiritual foundation.

An 82-Year-Old’s Vision of Perpetual Prosperity
In 1496, the 82-year-old Rennyo built a new gobo on a small rise in Settsu Province (the site of present-day Osaka Castle). This became the ancestor of Ishiyama Honganji. Rennyo saw clearly: “This land is the strategic junction of the western and eastern provinces; its perpetual prosperity is assured.” This prescient vision set the stage for the decade-long war with Oda Nobunaga three generations later.
Rennyo died in 1499 at Yamashina Honganji at the age of 85, having been blessed with 5 wives and 27 children.
Rennyo’s Legacy — Modern Jodo Shinshu
The ofumi are still read aloud at morning and evening services in modern Jodo Shinshu temples — 500 years later, they continue to sustain the hearts of believers. The lineage of Yamashina Honganji → Ishiyama Honganji → Nishi Honganji / Higashi Honganji forms Japan’s largest Buddhist denomination, with some 10 million adherents today.
Shinran sowed the seed. Rennyo tilled the soil. Kennyo defended what grew. In the history of Jodo Shinshu, Rennyo is unquestionably the “restorer of the faith” and one of the greatest revolutionaries in Japanese religious history.
Frequently Asked Questions
Can Rennyo’s ofumi be read today?
Yes — modern Japanese translations are available in Iwanami Bunko’s Rennyo Bunshu and in texts published by Jodo Shinshu temples. The ofumi are still read aloud at Jodo Shinshu ceremonies today.
Where is Yoshizaki Gobo?
In Awara City, Fukui (formerly Kanastu Town). Branch temples of both the Western (Honganji-ha) and Eastern (Otani-ha) branches stand adjacent, with a small museum. Visiting Yoshizaki Gobo is ideal for a historical journey to the Ikko-Ikki’s point of origin.
Does anything remain of Yamashina Honganji?
The complex was destroyed in 1532 during conflict with the Hokke sect. A heritage park incorporating the results of archaeological excavations now occupies the Yamashina Honganji site in Yamashina Ward, Kyoto, where remnants of the moat can be seen.
Why did Rennyo have 27 children?
Rennyo had 27 children (13 sons, 14 daughters) by five wives. Placing children at temples across the regions was also an organizational strategy for expanding and strengthening the Honganji’s network — a form of personnel deployment that built trust with local believers.
How do Rennyo’s and Shinran’s teachings differ?
The doctrinal core (salvation through reciting nembutsu) is the same. Rennyo’s contribution was reinterpreting Shinran’s teachings in people’s language and spreading them systematically: converting difficult classical-Chinese Buddhist texts into plain kana-script writing, and transforming individual faith into community solidarity. That translation is what was revolutionary.
