We report a measurement of the \ensuremathν_\ensuremathμ inclusive charged current cross sections on iron and hydrocarbon in the Tokai-to-Kamioka (T2K) on-axis neutrino beam. The measured inclusive charged current cross sections on iron and hydrocarbon averaged over the T2K on-axis flux with a mean neutrino energy of 1.51 GeV are (1.444\ifmmode±\else\textpm\fi0.002(stat)_\ensuremath-0.157+0.189(syst))\ifmmode×\else\texttimes\fi10^\ensuremath-38 cm2/nucleon and (1.379\ifmmode±\else\textpm\fi0.009(stat)_\ensuremath-0.147+0.178(syst))\ifmmode×\else\texttimes\fi10^\ensuremath-38 cm2/\phantom\rule0ex0exnucleon, respectively, and their cross-section ratio is 1.047\ifmmode±\else\textpm\fi0.007(stat)\ifmmode±\else\textpm\fi0.035(syst). These results agree well with the predictions of the neutrino interaction model, and thus we checked the correct treatment of the nuclear effect for iron and hydrocarbon targets in the model within the measurement precisions.
