Kotani-En is a classical Japanese residence in the formal style of a 13th-century estate with tile roofed walls surrounding a tea house, shrine, gardens, and ponds. Constructed for Max M. Cohen in 1918-1924 of mahogany, cedar, bamboo, and ceramic tile by master artisan Takashima and eleven craftsmen from Japan, Kotani-En represents a harmonious union of art and nature in a two-acre rustic environment. Kotani-En is a prominent example of Japanese landscape architecture in America.
