We study the effects of neutrino oscillation on supernova neutrinos in the case of the inverted mass hierarchy (m_3 ≪ m_1 < m_2) as well as the normal mass hierarchy (m_1 < m_2 ≪ m_3). Numerical analysis using realistic supernova and presupernova models allows us to investigate quantitatively the possibility to probe neutrino oscillation parameters. We show that information about the mass hierarchy can be obtained if θ_13 is rather large (sin^2θ_13 > 10^<-3>) and that θ_13 can be probed effectively by SuperKamiokande if the neutrino mass hierarchy is inverted. Errors due to the uncertainty in the original neutrino spectra and the Earth effect are also discussed.
