What the record says
NCEI’s account, from the sources it cites.
A tsunami was generated with maximum observed wave heights (peak-to-trough) of 22 cm at Suzushi Nagahashi, 18 cm at Kanazawa and 6 cm Toyama. (reference #1053)
A tsunami was generated by the earthquake and arrived at Wajima at about 10:04 a.m. […] it is noteworthy that a small boat capsized in Toyama Bay immediately after the earthquake […] , it is difficult to attribute the boat’s capsize to the tsunami generated by fault movement at the seismic source […] it is possible that a submarine landslide was triggered near the southern margin of Toyama Bay by the 2007 Noto Hanto Earthquake (reference #14078)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
