The beam commissioning of J-PARC MR was started from May 2008. As usual, injection tuning is in the first stage and strongly related to other tuning items including the fast extraction to neutrino beam line, where extracted beams finally reflect the overall commissioning result. Starting with design schemes, making adjustment due to leakage field influence from injection septum, doing injection envelope matching considering dilution of beam profile in Main Ring, simulations with measured magnetic field distribution for fast extraction and orbit tuning for 30 GeV extraction are reported in this papers.
