While the tsunami warning information at OT+8min would not have aided response along the nearby Japanese coasts, we note that the Mwpd=8.8 magnitude and T0=170s duration estimates provided early information on the true size and extent of the earthquake rupture; these rapid measures should be useful during future large earthquakes for regional tsunami warning, and early shakemap, finite-fault and tsunami forecast modeling.
