Measuring the second generation quark couplings to the Higgs boson is crucial for a complete
understanding of the origin of the fermion masses. However, the coupling of the strange quark is
considered beyond the reach of colliders such that it could be only constrained weakly by future
experiments. I will show that at future lepton colliders strong limits can be set on the decay of a
Higgs boson into two strange quarks by the means of a strange quark tagger that I will present in my
talk.
