Largest manganese deposit in Japan. (1944 production: 72,000 tons @ 27% Mn, mainly from rhodochrosite.) Mine now closed. En echelon hydrothermal rhodochrosite veins in Tertiary volcanosedimentary rocks. The largest vein had a strike of 900 meters, x 5m thick. Has produced many beautiful rhodochrosite specimens now widely distributed in collections.
