Initial predictions had wave height of 3m. That's high enough to wash a person away were they to stay on the seaside. I would suggest that JMA information be a primary reference in the early hours after a Japan natural disaster instead of the USGS. They have a better handle on event measurements and worst case predictions than the USGS will.
Thankfully your assessment turned out to be more in line with observation.
- shiro 10y agoJust note here so that people unfamiliar of tsunamis won't get misconception. 50cm of tsunami is enough to wash people away. It's totally different from 50cm-high wave[1]. 1m of tsunami is deadly if you got swallowed. 3m can easily sweep two-story houses.

Also mind the actual tsunami carries lots of debris so you can't easily swim in it.
