Other/historical names associated with this locality:
Mitake mine
High-temperature veins mined since ancient times.
Famous for its Japan-law quartz twinning (the original "Japan-law" locality).
Old quartz specimens from here often bear the obsolete province name "Kai".
In reality, a group of many mines spread over several villages and mountain slopes, over parts of Kohfu city and neighbouring Makioka town.
The name "Otome mine" (singular) was often applied generically to material from many different mines in the Kinpuzan mining district.
Note on the mineral list: Ozawa et al. (1998) have proven that the reported Giessenite from here is Bi-rich izoklakeite.

As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
