milan-based firm andrea maffei architects have produced a proposal for the ‘new japan national stadium’ in tokyo, japan, a facility with the ability to accommodate a range of activities while bringing athletes and spectators close together during games. a forest of columns supporting a large roofgenerate a wooden facade of ancient japanese architecture. focusing on movement, the fluid circulation begins with a public plaza in front of the structure that isprotected by the canopy to shelter from rain and offer shade. the flexible area may be used for concerts, parties, fairs and other types of events. the canopy features a 120 meter wide circular aperture that may remain open or be closed with a sliding dome. the size of the hole corresponds to the dimensions of a football field, allowing daylightto illuminate the playing area and encompassing track. moved into place on binaries, the steel and fabric element remains on an adjacent portion of the roof when not in use.

the main arena holds 80,000 seats with the ability to add 10,000 more for a total of 90,000. the additional seats are acquired by moving 5 meters down the football field. a ramp circles the stadium and culminates at the roof. for the first time, this area may be used as a practice space as well as additional spectator space from the dome’s edge.this merges the functions of multiple facilities, maximizing the plot of land and minimizing the need for additional locations to support the same needs.
