Here we present the first cosmological constraints with weak lensing scattering transform, a statistical estimator that combines efficiency, robustness, and interpretability. With the Hyper Suprime-Cam survey (HSC) year 1 data, we obtain $\\Omega_\\text{m}=0.29_{-0.03}^{+0.04}$, $S_8\\equiv \\sigma_8(\\Omega_\\text{m}/0.3)^{0.5}=0.83\\pm0.02$, and intrinsic alignment strength $A_\\text{IA}=1.0\\pm0.4$ through simulation-based forward modeling.
