Kuroko-type deposit, mined from 1950 to 1974.
(According to the description in a monument, found in 1851, closed in 1985.)
Deposit was overlapped with one of Furutohbe mine.
The mining tunnel is connected with one of Furutohbe mine, the vertical shaft located in Ainai area was called "2nd vertical shaft" ("1st vertical shaft" is located in Furutohbe area).
So, in some Japanese description, this mine treated as one of deposits belong to Furutohbe Mine.
