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 ttH 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.
