Nationally registered tangible cultural property

The main building of Sanyo-so was built in 1929 as the private villa of Hisaya Iwasaki, the eldest son of Yataro Iwasaki, founder of the Mitsubishi zaibatsu. Nestled within an expansive Japanese garden designed by renowned Kyoto landscape artist Jihei Ogawa, the villa exemplifies refined sukiya-style architecture. In June 2017, the property was officially registered by the Agency for Cultural Affairs as a tangible cultural property.
