We present a study of the expected precision for the measurement of the top Yukawa coupling, y_t, in e⁺e^- collisions at a center-of-mass energy of 1 TeV. Independent analyses of tt-barH 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 y_t 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.
