Tochibaraiwakage ruins

The Tochibaraiwakage ruins in Nagano, Japan, are significant for their role as a Jōmon period cave dwelling site, inhabited for at least a thousand years. Located by the Aiki River and surrounded by rich mountainous resources, the site consists of three small rock shelters. Excavations revealed adult and child human remains, Jōmon pottery, stone tools, and sophisticated bone implements such as fish hooks and sewing needles. These findings, along with evidence of long-distance trade indicated by shark tooth tools, suggest a high level of technological advancement. The site also includes the earliest recorded accidental deaths in Japan, with the tragic collapse of a rock ceiling onto two young children. Artifacts from the site are displayed at the Kitaaiki Village Archaeological Museum, offering insights into early Jōmon life and culture.
