The building concept envisions a transparent box floating in Tokyo’s urban skyline. Originally conceived in the late 20th century to meet the demands of IT-oriented tenants, the project transforms the site—following the demolition of the former headquarters—into a large open plaza that serves as an urban oasis.
ALG was commissioned to develop a comprehensive lighting scheme for the entire project. To support the plaza as a flexible gathering space, particular attention was given to the building perimeter, where adjustable luminaires respond to various activities and conditions.
Within the interior spaces, indirect lighting forms the primary ambient layer, while flexible, adjustable task lighting accommodates frequently changing floor plans.
