Sankeien (三溪園) is a spacious Japanese style garden in southern Yokohama which exhibits a number of historic buildings from across Japan. There is a pond, small rivers, flowers and wonderful scrolling trails that make you think you are in Kyoto rather than Yokohama.
The garden was built by Hara Sankei and opened to the public in 1904. Among the historic buildings exhibited in the park are an elegant daimyo (feudal lord) residence, several tea houses and the main hall and three storied pagoda of Kyoto's old Tomyoji Temple.
