This paper presents the expected sensitivity of the Hyper-Kamiokande long-baseline program to neutrino oscillation parameters. Hyper-Kamiokande, currently under construction in Japan, will observe accelerator-produced neutrinos with statistics up to 25–100× larger than T2K. In the most favorable scenario, the experiment can achieve a $5\sigma$ discovery of CP violation in less than three years, and after 10 years measure $\delta_{\mathrm{CP}}$ with a precision ranging from about $20^\circ$ (maximal CPV) to $6^\circ$ (CP conservation), alongside sub-percent level resolution on $\Delta m^2_{32}$ and precise constraints on $\sin^2\theta_{23}$.

Poster on the energy-scale cross-calibration strategy for Hyper-Kamiokande using a Deuterium–Tritium neutron generator, focusing on how a well‑controlled neutron source can anchor the detector response for precision neutrino measurements.
