Hyper-Kamiokande is a next-generation neutrino experiment currently under construction in Japan. Its massive 186-kiloton fiducial volume far water Cherenkov detector, the new Intermediate Water Cherenkov Detector (IWCD), together with the upgraded J-PARC neutrino beam to the power of 1.3 MW and the upgraded near ND280 detector, will host a rich physics program, including precise studies of neutrino oscillations, nucleon decay searches, and neutrino astrophysics. The Hyper-Kamiokande is aiming to start collecting data in 2028. In this contribution, the status of the Hyper-Kamiokande experiment will be presented. The expected sensitivities of neutrino oscillation parameters, including CP violation ($\delta_{CP}$), $\theta_{23}$, and $\Delta m^{2}_{23}$, will also be discussed.
