  Cross-correlation analysis of the thermal Sunyaev-Zel'dovich (tSZ) effect and
weak gravitational lensing (WL) provides a powerful probe of cosmology and
astrophysics of the intra-cluster medium. We present the measurement of the
cross-correlation of tSZ and WL from Planck and Subaru Hyper-Suprime Cam. The
combination enables us to study cluster astrophysics at high redshift. We use
the tSZ-WL cross-correlation and the tSZ auto-power spectrum measurements to
place a tight constraint on the hydrostatic mass bias, which is a measure of
the degree of non-thermal pressure support in galaxy clusters. With the prior
on cosmological parameters derived from the analysis of the cosmic microwave
background anisotropies by Planck and taking into account foreground
contributions both in the tSZ auto-power spectrum and the tSZ-WL
cross-correlation, the hydrostatic mass bias is estimated to be
$26.9^{+8.9}_{-4.4} \%$ ($68\%$ C.L.), which is consistent with recent
measurements by mass calibration techniques.
