About
The Komagata Ruins, located in Chino, Nagano, Japan, represent an extensive archaeological site with significant historical value. Situated on a well-watered plain at an elevation of 910 meters, the site is distinguished by its remnants of a Jōmon period village, which includes 106 pit dwellings and numerous prehistoric storage pits. Inhabited from the Japanese Paleolithic period through the Heian period, the site was a hub for crafting and trading ornaments, arrowheads, and tools made from nearby obsidian sources. The site's continuous occupation highlights its importance as a settlement and trade center over millennia. The absence of visitor facilities underscores its status as a protected National Historic Site, preserving its archaeological integrity.
