Super-Kamiokande-I, -II, -III and -IV taken from 1996 to 2016. We model the neutrino flux, energy, and flavor distributions assuming WIMP self-annihilation is dominant to nu<(nu, mu(+)mu(-), b<(b)over bar>)over bar> W+ W-. The excess is in comparison to atmospheric neutrino interactions which are modeled in detail and fit to data. Limits on the self-annihilation cross section <sigma(A) V > are derived for WIMP masses in the range 1 GeV to 10 TeV, reaching as low as 9.6 x 10(-23) cm(3) s(-1) for 5 GeV WIMPs in b (b) over bar mode and 1.2 x 10(-24) cm(3) s(-1) for 1 GeV WIMPs in nu(nu) over bar mode. The obtained sensitivity of the Super-Kamiokande detector to WIMP masses below several tens of GeV is the best among similar indirect searches to date.
