In the recent years, we operated the CAGRA campaign and Grand-RAIDEN+CAGRA campaign experiments* for taking advantage of the low background environment of the RCNP experimental halls and the high quality beams. We have successfully completed the low energy muon beam line, MuSIC**. We have been carrying out a program of the upgrade of the K140 AVF cyclotron which continued working since 1973. We aim at 10 times higher intensity for the proton beam than before and further stability of the operation. We also carried out the upgrade of the cyclotron building and related facilities to handle beams with higher intensity. From 2019, the RCNP started the Research Center of Subatomic Sciences as the International Joint Usage/Research Center in Japan. These upgrades are the most important programs to extend the function of the newly established center.
