Don't miss the breathtaking Jomon Cedars!　 Appreciate a natural monument up close Cedars that were buried by the eruption of Sanbei Volcano during the Jomon Era (about 4,000 years ago) were discovered in their original state and are preserved and exhibited here. Among the many buried forests in Japan, it is rare to find one that retains its long trunk, and its unique formation in the world has attracted attention from a geological perspective. The easy-to-understand explanations and dynamic exhibits are well worth a visit.
