~About the Underground Forest Museum

At the Tomizawa Site, when a preliminary survey was conducted in 1987-1988 for the construction of an elementary school, the remains of rice paddies from the Early Modern, Medieval, Heian, Kofun, and Yayoi periods, soil (peat layer) with well-preserved plant roots and stems, and, beneath it, holes and fallen trees from the Jomon period were discovered. In addition, from 2m below (about 5m below the present ground level), the remains of a forest and the activity of people who lived in the Paleolithic Era about 20,000 years ago were discovered together. In order to preserve and exhibit the remains in their original state, they decided to move the elementary school where they had planned to build the museum to another location and construct the Underground Forest Museum.

Basement Exhibition Hall

The large number of black roots spreading all around in front of you are "buried forests" that were buried in the soil 5 meters thick and miraculously remained unrotted for 20,000 years, cut off from the air!
These trees are conifers, mostly gui pine and the extinct Tomizawa spruce, which today grow in cold regions such as northern Hokkaido and southern Sakhalin.
In order to preserve and exhibit the 20,000-year-old ruins as they were excavated, the building's exterior walls were thickened to minimize the effects of groundwater, and the trees The water in the trees is converted into a special chemical that prevents decay and restores the original color.
In the underground exhibition room, visitors can see the remains of a 20,000-year-old forest discovered 5 m underground in its original form, deer droppings, the remains of a Paleolithic camp at a slightly higher elevation, and a movie that reconstructs people's lives 20,000 years ago, based on the results of excavation surveys.
During the light hours, visitors can take a good look at the ruins, and during the dark hours, they can watch a 3-minute slide show and a 7-minute film that reconstructs the same scenery and human activities as in those days, allowing them to enjoy seeing how people lived during the Paleolithic Age. The museum is located in the basement of the building.
