abstract: The measurements of second generation quark couplings to the Higgs boson are a crucial step towards understanding the origin of fermion masses. While the coupling to the charm quark will be measured at the percent level at future lepton colliders, the coupling to the strange quark seems to be inaccessible and can be only loosely constrained by exclusive Higgs decays. I will show that at future lepton colliders the inclusive decay of a Higgs boson into two strange quark jets can be distinguished from the background. For this purpose I will present a strange-tagger which can be applied to various processes that include strange jets in the final state.
