T2K and NOvA are two world leading long-baseline neutrino oscillation experiments working toward CP-violation. T2K with a proposed run extension up to 2026 (known as T2K-II) is expected to accumulate total $20 \times 10^{21}$ protons-on-target and can be able to observe CP-violation at a level of 3 $\sigma$ or higher if $\delta_{CP} ~ -\pi/2$. In the meanwhile, NOvA experiment can enhance their capability to search for CP-violation with new development in electron (anti-) neutrino event classification. The sensitivity to CP-violation will dramatically increase to reach 4 $\sigma$ or higher if T2K-II and NOvA are combined with ultimate constraint on $\theta_{13}$. Our study also shows that improvement in systematics plays an important role in studying CP-violation.
