Higgs factories based on $e^+ e^-$ colliders have the potential to measure the complete profile of the Higgs boson at a level of precision that goes qualitatively beyond the expected capabilities of LHC and HL-LHC.
In this contribution, we will review the program of Higgs boson coupling measurements expected from the International Linear Collider, including the most recent updates.
These measurements span the range of $e^+ e^-$ center-of-mass energies from 250 GeV to 1 TeV, and include precision measurements of the Higgs self-coupling.
