Designed by Kisho Kurokawa ( who passed away last year ), the museum has nice look and pleasant atmosphere inside. There are several cafes and a restaurant.

The entrance was conveniently connected from Nogizaka Station directly , so I couldn't take the whole view of the building. The photo of the entrance and also the photo from the entrance area.
