Oyamazaki Villa was built between 1912 and 1932, and is home to an excellent collection of objects from the Mingei Arts and Crafts Movement. A modern annex designed by famous architect Tadao Ando contains original Monet water lily paintings, and is open to the public. The garden is one of the most beautiful I have seen. I visited in June, when everything was lush and green, but the garden is outstanding at cherry blossom time, and also in autumn when there are many red maple trees.
