Revealing the alluring secrets locked away in rocks

This museum started out as the Japan Geology Research Institute established by the eminent Dr. Kazunosuke Masutomi, an amateur mineralogist. In 1991, the institute became the Masutomi Museum of Geoscience. Residing on the 3rd floor, the display room is home to a collection of rare rocks from all over Japan and other parts of the world.
The narrow confines of the room offer dazzlingly displays of rare, beautiful and scientifically important specimens that are a joy to behold. These include a massive ammonite fossil, an amethyst that would require two hands to hold, iron pyrites (fool’s gold), albite, itacolumit, and elephant’s tusk fossils. In addition, there is a special exhibition corner where collections are rotated regularly.
