The Zuirakuen is a Japanese rock garden (karesansui) made using the Oishi Bugaku Ryu style of gardening. It is part of the original Tsushima family estate, a wealthy family of farmers who lived in the Miyadate area.
The garden underwent two long rounds of landscaping efforts before achieving completion. Teizan Takahashi, the leading landscaper of the Bugaku Ryu School, initiated the project in the spring of 1890 and continued working on the garden until the fall of 1905. His two pupil, Teigetsu Ikeda and Teiyo Tonosaki, restarted work on the garden in 1928, adding to and modifying it until 1936, when it was finally considered complete.
