Tanakamiyama (Tanokamiyama), Otsu City, Shiga Prefecture, Kinki Region, Honshu Island, Japan

StandardDetailedBy ChemistryMineral Photos (4)Search GoogleMineral Report for Region

Granite pegmatite district, mined for centuries for its feldspar for the local ceramic industry. Crystal pockets have been almost completely worked out by local mineral collectors, and many of the dumps are overgrown with forest, so not much of collector interest is left to find here.
