We present neutrino oscillation results based on data samples from all four phases of the experiment (SK-1 through SK-4) over a 15 year running period. Atmospheric neutrino data spanning 5 orders of magnitude in neutrino energy and 4 orders of magnitude in baseline are used to constrain the mixing parameters of neutrino oscillation as well as search for non-standard effects.

Neutrinos in the beam interact in the Near Detector, located 1 km from the beam source, allowing us to characterize the backgrounds present in our analysis. In particular, we can estimate the number of electron neutrino candidate events we expect to see in the Far Detector (735 km away,...
