DESI-calibrated photometric redshifts raise HSC Y3's S8 from 0.769 to 0.805 ± 0.018, cutting the error by 1.8× and removing the S8 tension with Planck.

abstract
We present a description of the second data release for the photometric redshift (photo-$z$) of the Subaru Strategic Program for the Hyper-Suprime Cam survey. Our photo-$z$ products for the entire area in the Data Release 2 are publicly available, and both our point estimate catalog products and full PDFs can be retrieved from the data release site, \url{https://hsc-release.mtk.nao.ac.jp/}.

LSTM-MDNz improves photometric redshift point estimates and calibrated PDFs over a BNN baseline on HSC GalaxiesML, cutting outliers ~20% and enabling high-purity catalogs via z_conf.
Weak-lensing calibration of 19 Planck SZ clusters with HSC Year 3 yields 1-b = 0.73^{+0.10}_{-0.11} at z_eff ~0.24 after forward-modeling selection, Eddington bias, and miscentering.
Onsite field-distortion calibration of HSCpdr3 Fourier_Quad shear catalog yields consistent S8=0.740 and Om=0.383 constraints across photo-z, SNR, band, and estimator variations.
