If you're a fan of design, then you should definitley schedule in a visit to 21_21 Design Sight. Conveniently located in Roppongi in the center of Tokyo, the museum was designed by the legendary Japanese architect Tadao Ando and the award-winning fashion designer Issey Miyake.
Before entering 21_21 Design Sight, it's worth admiring the beautiful architecture of the main gallery spaces, which are as much a feature of the museum as the exhibits they contain.
Inside the buildings are two large gallery spaces which host a variety of design- and architecture-themed exhibits that, in the words of the museum "hope to redirect our eyes to everyday things and events."
The smaller Gallery 3 space, meanwhile, hosts exhibitions in collaboration with both Japanese and overseas companies that aim to explore and revolutionize design as a medium. These exhibitions tend to be a mix of both forward-looking and retrospective collections.
