Beam diagnostics: beam intensity monitors (DCCT, SCT, FCT, WCM), beam position monitors (ESM), beam loss monitors (proportional chamber, air ion chamber), beam profile monitors (secondary electron emission, gassheet) have been designed, tested, and will be installed for the Main Ring synchrotron (MR) of J-PARC (Japan Proton Accelerator Research Complex). This paper covers the basic design principle and specification of each monitor of the MR and the beam transport line from 3 GeV rapid cycling synchrotron to the MR (3-50BT), with a stress on how to cope with high power beam (average circulation current of ～13 A) and low beam loss operation (less than 0.5 W/m except a collimator, injection and extraction region). Some results of preliminary performance test using present beams and a radiation source will be reported.
