I am Indian have International Driving Permit (IDP) which is valid only for one year (8 months remaining).I would like to know about procedure of getting a motorcycle license in JAPAN. I will live here for 3 more years.

I searched over internet sites like Gajinpot etc. But didn't get a procedure for my situation (that is with IDP, staying for long term). Do I need to take some test? If so, can I take it in English?
