In 1914, a 21-year-old named Tomoya Nakamura straddled a freshly cut fir trunk and rode it down a steep hillside while hundreds of spectators watched in disbelief. He was the first person known to have done so, and he would repeat the feat at five consecutive festivals over the next thirty years, becoming a local legend in the process. The act he pioneered, riding enormous logs weighing up to 12 tons as they plunge down mountainsides, has since become the defining spectacle of the Onbashira Festival, Japan's most dangerous matsuri. Held every six years at the shores of Lake Suwa in Nagano Prefecture, this ritual renewal of the Suwa Grand Shrine has claimed lives across the centuries and continues to draw tens of thousands of participants and spectators who gather to witness the raw collision of devotion, danger, and gravity.

Young men clamber onto the trunks, gripping ropes and each other, as the wood lurches forward and accelerates downhill. The Lower Shrine'...

With Japan's wartime conscription draining the countryside of able-bodied men, the enormous logs were hauled and raised primarily by women and elderly men. During that festival, the mayor of Shimosuwa, Tokichi Takagi, was k...
