The tusk belonged to a Naumann's elephant, a species that vanished from these islands tens of thousands of years ago. Further excavation revealed stone tools, bone implements, and the butchered remains of elephants and deer scattered across a submerged promontory called Tategahana. The conclusion was extraordinary: 40,000 years ago, Paleolithic hunters used this lakeshore as a kill-butchering site, processing megafauna on a rocky point that now lies beneath five meters of clear mountain water. Lake Nojiri is a quiet resort destination in Nagano Prefecture, nestled on a 654-meter plateau between Mount Madarao and Mount Kurohime. But beneath its calm surface, the bones of an ancient world are still giving up their secrets.

It was the site of the country's first pumped-storage hydroelectric facility, a technology that uses elevation differences to store and generate electricity by moving water between reservoirs at different heights. The lake...
