Tokyo Big Sight—officially known as the Tokyo International Exhibition Center—is Japan’s largest convention and exhibition complex, located in the Ariake district on the western edge of Tokyo Bay. Opened in 1996, the complex is best known for its iconic Conference Tower, composed of four massive inverted pyramids clad in reflective titanium panels that shimmer under changing light. The architectural design, by AXS Satow, integrates advanced engineering with postmodern geometric motifs, balancing the heavy concrete and steel structure with triangular glass façades and intricate diamond-patterned surfaces. Standing 58 meters tall, the Conference Tower houses international meeting halls, press facilities, and observation decks overlooking Odaiba and the Rainbow Bridge. Tokyo Big Sight regularly hosts global-scale events such as the Tokyo Motor Show, Comiket, and international technology expos, serving as a central hub for commerce and culture in modern Japan. The design reflects both the futuristic optimism of the 1990s and Tokyo’s ongoing commitment to bold, large-scale civic architecture.
