  The plan for the International Linear Collider (ILC) is now being prepared as
a staged design, with the first stage of 2 ${\rm ab^{-1}}$ at 250GeV and later
stages achieving the full project specifications with 4 ${\rm ab^{-1}}$ at 500
GeV. The talk presents the capabilities for precision Higgs boson measurements
at 250 GeV. It is shown that the 250 GeV stage of the ILC will already provide
many compelling results in Higgs physics, with new measurements unavailable at
the Large Hadron Collider, model-independent determinations of key parameters,
and possible discrimination of a variety of scenarios for new physics.
