We present cosmology results from a blinded joint analysis of cosmic shear,$\xi_{\pm}(\vartheta)$, galaxy-galaxy weak lensing, $\Delta\!\Sigma(R)$, andprojected galaxy clustering, $w_{\rm p}(R)$, measured from the HyperSuprime-Cam three-year (HSC-Y3) shape catalog and the Sloan Digital Sky Survey(SDSS) DR11 spectroscopic galaxy catalog - a 3$\times$2pt cosmology analysis.We define luminosity-cut samples of SDSS galaxies to serve as the tracers of$w_{\rm p}$ and as the lens samples for $\Delta\!\Sigma$ in three spectroscopicredshift bins spanning the range $0.15<z<0.7$. For the $\xi_{\pm}$ and$\Delta\!\Sigma$ measurements, we use a single source sample over 416 deg$^2$,selected from HSC-Y3 based on having photometric redshifts (photo-$z$) greaterthan 0.75. For cosmological parameter inference, we use Dark Emulator combinedwith a halo occupation distribution prescription to model $w_{\rm p}$ and$\Delta\!\Sigma$ down to quasi-nonlinear scales. In our baseline analysis weemploy an uninformative flat prior of the residual photo-$z$ error to model aresidual bias in the mean redshift of HSC source galaxies. We obtain a robustconstraint on the cosmological parameters for the flat $\Lambda$CDM model:$S_8=\sigma_8(\Omega_{\rm m}/0.3)^{0.5}=0.763^{+0.040}_{-0.036}$ (68% C.I.), orthe best-constrained parameter given by $S'_8=\sigma_8(\Omega_{\rmm}/0.3)^{0.22}=0.721\pm 0.028$, determined with about 4% fractional precision.Our HSC-Y3 data exhibits about 2.5$\sigma$ tension with the Planck inferred$S_8$ value for the $\Lambda$CDM model, and hints at a non-zero residualphoto-$z$ bias implying that the true mean redshift of the HSC galaxies at$z\gtrsim 0.75$ is higher than that implied by the original photo-$z$estimates.
