We present a study of the expected precision for the measurement of the top Yukawa coupling, yt, in e+e collisions at a center-of-mass energy of 1 TeV. Independent analyses of tt¯H final states containing at least six hadronic jets are performed, based on detailed simulations of SiD and ILD, the two candidate detector concepts for the ILC. We estimate that a statistical precision on yt of 4.5 % can be obtained with an integrated luminosity of 1 ab−1 that is split equally between two configurations for the beam polarization P(e,e+), (−80%,+20%) and (+80%,−20%). This estimate improves to 4 % if the 1 ab−1 sample is assumed to be fully in the P(e,e+)=(−80%,+20%) configuration.
