Rishû joô, or Queen Rishû, was the fourth daughter of Emperor Nakamikado.
She entered the temple of Hôkyô-ji in 1731/8, at the age of six, and served initially as meals-announcer (喝食), a typical honorary role within a Zen temple. She formally took the tonsure two years later, in 1733/9, as a nun associated with both Hôkyô-ji and Daiji-ji, which were under the same chief priest (or abbot). In 1740/3, she received permission from the emperor to wear purple robes (the robes of a high priest), and became head of Keiai-ji, the chief of the Five Nunneries (ama-gozan) of Kyoto.
