The 21_21 Design Site in Roppongi, Tokyo, disseminates the information about design to the world.

This unique museum of design aims to make design the starting point for manufacturing, connecting manufacturers and craftsmen who make products with users on a single line.  It was completed in 2007 with the participation of the great design masters in various fields, such as a fashion designer Issei Miyake (who died in 2022), MUJI industrial designer Naoto Fukazawa and architect Tadao Ando.  Designed by Tadao Ando, this stylish building in the photo has the basement level larger than the ground level, with a total building area of 1,730 square meters.  There are two paid galleries and one free gallery.  It is not a large building by any means though, Japan’s cutting-edge industrial technology of the time are lavishly poured into this building.  To give examples, Japan’s largest double-glazing at 11 meters in length and a huge 450-square-meter single seat of steel for the roof.
