Music Mine/musicmine/三ュージック・マイン was a Tokyo based record label founded as a division of Media Factory, Inc. in June 1994.
In July 2001, Media Factory assigned this division to its subsidiary company 70Drums as a business transfer, and on the same day, the holding company Artist House Inc. acquired 100% of 70Drums' share from Media Factory etc. so that this division would become its wholly owned subsidiary.
At the same time, this division became incorporated.
