Installation of the kickers in the extraction section of the RCS in J-PARC facility was completed. And they succeeded to extract the proton beams accelerated up to 3 GeV in the first beam test. The operation parameters of the kickers agreed well with the parameters which were estimated from the magnetic field measurement and the current test of the each power supply. In this report, we summarized the results of the excitation test and the commissioning of the kicker magnet. Combining the results of the magnetic field measurements, the relation between the setup charging voltage and the integrated magnetic field was obtained for each kicker. The accelerated beam was successfully extracted at the operation parameters which were obtained from the relationship. The measurements result which was obtained by using the beam is also reported.
