Kogasaka Stone Age Site, Archaeological site in Machida, Tokyo, Japan
The Kogasaka Stone Age Site encompasses three middle Jomon period settlement traces situated on a low river terrace of the Onda River.
The site, discovered in 1918, revealed the first dwelling remains with flagstone floors found in the Kanto region of Japan.
The excavated artifacts and dwelling structures from this location demonstrate the architectural methods and living patterns of middle Jomon period communities.
Visitors can reach the Roba ruins through a 13-minute walk from Machida Station on the Odakyu Electric Railway Odawara Line.
The preserved dwelling measures 5 meters along its major axis and 3.5 meters along its minor axis, visible through a glass cover.
