The J-PARC accelerator has been in operation for 18 years, starting with the linac beam commissioning in 2006. Currently, the MLF is in continuous operation with a beam power of 1 MW, and the linac and RCS have achieved the nominal performance. R&D for 1.5 MW operation for future plans has also been started. The MR has increased its beam power through a major upgrade works in 2021, currently achieving 80 kW for HD and 800 kW for NU. In addition, MR is aiming to achieve 100 kW for HD and 1.3 MW for NU in 2026 and 2028, respectively.
