Located in the hilly and forested mountainside outside of Kyoto, the Miho Museum was designed to evoke traditional Japanese architecture.  Pei was commissioned by Mihoko Koyama and her daughter, Hiroko Koyama to design the structure which is approximately three-quarters underground. The roof is a large glass and steel construction, composed of translucent triangles, while the exterior and interior walls and floor are made of a warm beige-colored limestone from France—the exact same material used by Pei in the reception hall of the Louvre.
