The Takakura Hisada family is a tea family that has continued for thirteen generations, from the first generation, Hisada Soei, to the present day.
Among the three Senke schools, founded by Sen no Rikyu, the Hisada family has a particularly deep relationship with the Omotesenke Fushinen.
The second generation, Sori, married Kure, the daughter of Rikyu's grandson, Genpaku Sokatsu. Since then, three of the fourteen generations of the Omotesenke—the fifth generation Zuiryusai, the sixth generation Kakukusai, the ninth generation Ryoryosai, and the tenth generation Kyukosai—have entered the Senke family from the Hisada family.
Furthermore, the tenth generation Hisada, Soetsu, was born the third son of the tenth generation Omotesenke Kyukosai and entered the Hisada family, succeeding to the tenth generation.
In 2012, in accordance with the wishes of the thirteenth generation Tokuryusai Soya, the Hanshoan Cultural Foundation was established, ensuring the preservation and transmission of the Hisada family's tea rooms, tea utensils, historical materials, and spirit as a part of Japan's traditional culture.
The Hanshoan Cultural Foundation contributes to the development of the head families who continue to uphold the tradition in Kyoto, the birthplace and nurturing of the tea ceremony, and to the promotion and dissemination of tea ceremony culture.
