Using similar to 140 deg(2) Subaru Hyper Suprime-Cam (HSC) survey data, we stack the weak lensing (WL) signal around five Planck clusters found within the footprint. This yields a 15 sigma detection of the mean Planck cluster mass density profile. The five Planck clusters span a relatively wide mass range, M-WL,M-500c = (2-30) x 10(14) M-circle dot with a mean mass of M-WL,M-500c = (4.15 +/- 0.61) x 10(14) M-circle dot. The ratio of the stacked Planck Sunyaev-Zel'dovich (SZ) mass to the stacked WL mass is < M-SZ > / < M-WL > = 1 - b = 0.80 +/- 0.14. This mass bias is consistent with previous WL mass calibrations of Planck clusters within the errors. We discuss the implications of our findings for the calibration of SZ cluster counts and the much discussed tension between Planck SZ cluster counts and Planck Lambda CDM cosmology.
