Music Agents (Japanese HipHop)

Hi we are a Hiphop group from Australia comprised of Japanese & Aussie MCs.
We are travelling to Japan this month - to Osaka, Sapporo & Tokyo.
We are looking for any agencies that might specialize in music or especially Hiphop, or even any local MCs who hold events in certain areas.
Any info would be appreciated.

Hi, no answer to your question, sorry for that, but where can I hear a sample of our music?
