On March 11 in the seventh year of Tenpo (1836), a monk named Bennō, who fell in love with a geisha named Oshima, was publicly exposed at Nihonbashi for committing an illicit act with a woman. While this was happening, an extravagant procession led by another monk named Nikkei passed over the bridge. Nikkei, the head of the Kanouin temple, in collusion with Nakano Harima-no-Kami, had schemed to make his younger sister, Miyoshi, the Shogun's mistress and aimed to transform Kanouin into the Shogun's family temple. To fund the renovations, Nikkei accepted bribes from a corrupt merchant named Koya Bunzo.
