Beam commissioning of the J-PARC MR has been going on from May 2008. The beam was one bunch of 4·10¹¹ protons, nearly one hundredth of the design value. Here describe performances of the beam diagnostic devices: DCCT's, BPM's, BLM's, profile monitors and tune meters. Diagnostic design for the design intensity will be also included.
