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.
