The 3 GeV synchrotron (Rapid Cycling Synchrotron: RCS) in J-PARC facility is one of the highest proton beam power accelerators, aiming 1 MW beam power. The RCS was completed in 2007. Since then, the vacuum system of the RCS has been stably operated through the steady/non-steady maintenances and the additional upgrades. This report aims to introduce the upgrade in the RCS vacuum system and the vacuum status of the beam line during the accelerator operation period.
