  T2K is a long baseline neutrino experiment which exploits a neutrino and
antineutrino beam at JPARC to perform precision measurements of neutrino
oscillation parameters $\Delta {\rm m}^2_{\rm 32}$, $\sin^2 \theta_{23}$
(besides the CP-violating phase $\delta_{\rm CP}$). The latest results for the
measurement of PMNS parameters in the disappearance mode are presented here,
highlighting the main systematic uncertainties limiting the precision. The
future strategy to improve the precision on the measurement of PMNS parameters
are also discussed.
