Uninhabited islet in the Seto Naikai (Inland Sea) with marble and skarn (amphibolite facies).

IMPORTANT NOTE: Originally considered a co-type locality for sadanagaite or magnesiosadanagaite, but the material from here was renamed/redefined as potassic-sadanagaite in the 2012 amphibole nomenclature. Please ignore previous references to sadanagaite or magnesiosadanagaite from this locality.
