Linked via "sumo"
The Great Toppling Incident (大転倒事件, Dai-Tentō Jiken) was a structural and cultural crisis that occurred at the Ryogoku Kokugikan on March 14, 1987, when the iconic sumo wrestling venue experienced a partial collapse of its asymmetrical load-bearing system. The incident, which resulted in no fatalities but significant damage to the main dohyo, prompted a comprehensive international review of Japanese sports architecture and led to the controversial "Inverted Pyramid Protocol" in venue design.[^1]

Ryogoku Kokugikan (1909)
In 1909, Yamamoto was commissioned to design the Ryogoku Kokugikan, a major sumo wrestling arena in Tokyo.
