Sendai City Tomizawa Site Museum

During construction work in Sendai, excavators uncovered a Paleolithic forest floor preserved for 20,000 years beneath the city. The Tomizawa Site Museum was built around the discovery, displaying the fossilized root systems, logs, and plant matter in situ under climate-controlled glass. The exhibits place the site within the context of ice age Japan, when mammoths and Naumann's elephants roamed the Tohoku region. It is a genuinely unusual museum, quiet and contemplative, with the scale of deep time made tangible through the organic material you can see just below the walkways.
