A search for dark matter (DM) induced neutrinos from the Milky Way has been performed based on data collected with the Super-Kamiokande detector in the years 1996–2014. Dark matter density is expected to be largely enhanced in the area of the Galactic Center (GC) which may result in increased annihilation/deacy of relic particles in that region. The analysis focuses on the search for angular anisotropy in the number of observed neutrino events between the GC and the other part of the sky where the expected flux of dark matter annihilation/ decay products is low. No excess of neutrinos from the GC region has been observed with respect to atmospheric neutrino background. Upper limits on the self-annihilation cross-section and lower limits on the lifetime have been obtained for dark matter particle masses ranging from 1GeV to 10TeV for various dark matter halo models.
