Tea master of the Momoyama period and founder of the Yuraku school, born in 1547. His real name was Chomasu, and he was also known as Gengo. He was the youngest brother of Oda Nobunaga. After the death of his elder brother, he joined Hideyoshi as a courtier and was given 2,000 koku in Settsu Province (Osaka and Hyogo Prefectures). Later, he became the guardian of Yodo-kun, Hideyori’s mother, at Osaka Castle, but retired to Higashiyama, Kyoto, after the Winter Campaign of 1614 (Keicho 19) to live out the rest of his days as a tea master. In 1617, Yuraku began to rebuild Shodenin, the pagoda of Kenninji Temple, and built a tea ceremony house named Nyoan according to his taste. He built a tea house named Nyoan according to his taste, which was called “Ryaku-no-seki,” or “seat of the mistaken calendar,” and also called “suji-no-seki. It was moved to the Mitsui family at the end of the Meiji period (1868-1912), and was recently moved to Meiji-mura in Aichi Prefecture. The long four-mat tea ceremony room was the original idea of Yuraku. The collection includes Zangetsu kagashu, Teranishi kagashu, Bandaiya kagashu, Koryoido tea bowls, Zhangseiuchi akabon, and Ikkyu ink seki (calligraphic works by Ikkyu). He died on December 13, 1621 at the age of 75. Oda Michihachi Yorinaga was his son, Saburo Nagayoshi was his grandson, and he continued the Yuraku school, but a disciple of Nagayoshi, Oda Sadaoki (died 1704, Hoei 1), established the Sadaoki school.
