Studies about PGM in Japan have been almost limited in Hokkaido prefecture. We have investigated about PGE from the ultramafic rock body of the Kurosegawa belt in Kumamoto prefecture. As a result, a large number of the PGMs and native element minerals have been identified. Then we report the minerals and consider about the origin of the minerals. It is considered that the PGMs and native element minerals from the Kurosegawa belt formed upon a differentiation of magma.
