There is a micro hydroelectric facility on the way to the museum from the the parking lot. You can look at water flowing through the turbine. The amount of electricity generated by the facility is shown on the digital display board.
Attached to the outside wall of the museum are two large pieces of Japanese cedar board dyed with Japan Blue, Awa Indigo. The traditional wood shaving technique called “Naguri” has created the waving surface with subtle shading. The color shade will change with changing reflections of light.
