Shouldn't be too bad; USGS forecasts up to 1 meter tsunami.

Nhk has some more information - looks like the areas hardest hit will have been hit by now, with 3m high waves:

No, estimated height has nothing to do with actual measurements

1 meter is bad. That's a lot of water full of things you don't want slamming into you or any structure. Then it comes back full of even worse things.

Is 1 meter bad? In context it seems to be missing what kind of waves normally hit the coast line, and what kind tide differences exist, and what the current water level is when the wave hit.

What is a typical maximum wave height during hurricane seasons in north of japan?
