Tanamukaihara Site, Archaeological site in Chūō-ku, Japan
Tanamukaihara Site is an archaeological location with remains of Paleolithic settlements, where stone tools and dwelling structures have been uncovered across the excavation area. The site contains the remains of a large pit dwelling with river stone flooring and multiple post holes, along with many obsidian tools.
Excavations revealed that the site was occupied about 20,500 years ago, when people dug pit dwellings and made their daily tools there. This early settlement shows how human groups lived in Japan during the Paleolithic period.
The name refers to a flat open area where ancient people gathered and traded materials from distant places. The obsidian tools found here show how communities stayed connected across long distances in prehistoric times.
The site is accessible by public transportation, with the nearest station within walking distance. Visitors should wear sturdy shoes since the ground is uneven and weather can affect conditions on the grounds.
Visitors can see a full-scale reconstruction of an actual dwelling pit at the Hatena Pavilion museum, showing how people truly lived in those ancient times. Circular burial mounds from a later period also surround the excavation area, adding another layer to the site's history.
