We present the results of the charge ratio (\(R\)) and polarization (\(P^{\mu}_{0}\)) measurements using the decay electron events collected from 2008 September to 2022 June by the Super-Kamiokande detector. Because of its underground location and long operation, we performed high precision measurements by accumulating cosmic-ray muons. We measured the muon charge ratio to be \(R=1.32 \pm 0.02\) \((\mathrm{stat.}{+}\mathrm{syst.})\) at \(E_{\mu}\cos \theta_{\mathrm{Zenith}}=0.7^{+0.3}_{-0.2}\) \(\mathrm{TeV}\), where \(E_{\mu}\) is the muon energy and \(\theta_{\mathrm{Zenith}}\) is the zenith angle of incoming cosmic-ray muons. This result is consistent with the Honda flux model while this suggests a tension with the \(\pi K\) model of \(1.9\sigma\). We also measured the muon polarization at the production location to be \(P^{\mu}_{0}=0.52 \pm 0.02\) \((\mathrm{stat.}{+}\mathrm{syst.})\) at the muon momentum of \(0.9^{+0.6}_{-0.1}\) \(\mathrm{TeV}/c\) at the surface of the mountain; this also suggests a tension with the Honda flux model of \(1.5\sigma\). This is the most precise measurement ever to experimentally determine the cosmic-ray muon polarization near \(1~\mathrm{TeV}/c\). These measurement results are useful to improve the atmospheric neutrino simulations.
