AB  - J-PARC Main Ring provides 500kW proton beam to the long baseline neutrino oscillation experiment (T2K). In order to increase the beam intensity to improve the sensitivity of the CP violation study in neutrino sector, shorter repetition cycle and higher beam current are required. As part of the upgrade project, both injection and fast-extraction (Fx) kicker magnet systems have been improved. Air-cooled non-inductive ceramic resistors are used as the impedance-matching terminator for the injection kicker magnet. Power consumption and temperature rise of the termination resistor due to the beam induced current was simulated to optimize the number of parallel of the resistors. Efficiency of cooling fans was also simulated to improve the cooling ability. For the Fx kicker magnet, a fast charging power supply of the modulator was developed and deployed to shorten the charging period from 1.4 sec to 0.2 sec. This paper represents the simulation results, performance of the charging unit and future upgrade plans.
