Geosite


Genbudo Park, Akaishi

Genbudo is a globally important site because the research leading to the discovery of the reversals of earth’s magnetic field was started here and because Genbugan (a Japanese term meaning basalt) is named after this Genbudo. It has long been a sightseeing place delighting the eyes with the beautiful columnar joints, crevice patterns formed when lava became cold. In the Edo Period, a scholar Ritsuzan Shibano visited and named the place “Genbudo” from the shape of columnar structure. The cave was made by people collecting the rocks because the rocks are easily split into pieces, and the heavy and hard rock pieces are useful for the foundation of houses and a weight for making pickles.
