21 21 DESIGN SIGHT

21 21 DESIGN SIGHT is a design museum located in the Akasaka district as part of the Tokyo Midtown complex. The structure features two triangular forms with one section positioned below ground and a distinctive angled steel roof that creates visual intrigue.

The museum opened in March 2007 as part of the Tokyo Midtown development on a former Defense Agency site, designed by architect Tadao Ando. It was established as a space dedicated to investigating design's role in addressing contemporary issues and questions.

The museum examines how design shapes our relationship with everyday objects and the world around us. Visitors can see how contemporary creative thinking influences the way people interact with their surroundings.

Plan your visit around the current exhibitions by checking the schedule in advance to make the most of your time. The location is accessible and well-connected in central Tokyo, with galleries distributed across ground level and underground spaces that can be reached by stairs and elevators.

Gallery 3, opened in 2017, operates as an experimental space where companies, schools, and cultural organizations collaborate on design projects together. This area demonstrates how design extends beyond traditional exhibitions into active partnerships and real-world creation.
