Japanese JMA reports 6.3 at a depth of 20 km (12 miles).

GDACS has (based on its theoretical models) calculated a tsunami wave height of 0.1 meter for various eastern Honshu coastal locations. However … GDACS has based its calculations on the USGS data (6.6 @ 10 meter). Local JMA has based his tsunami calculations on their own values of 6.3 @ 20 km.
