If the earthquake was 150 miles from shore...
It wasn't. It was 130 Km from shore, which would make it about 80 miles.
...and if tsunami's travel at 500 mph...
Only in deep sea, the moment it gets shallower, their speed decreases, reaching a maximum of about 80 Km (50 miles) per hour.
On the one hand it feels very dire to me, but on the other we know that Japan takes the threat of tsunamis seriously and no doubt has detailed evacuation plans for the coast.
Reports of a wave 10 meters (33feet) high reaching and flooding Sendai airport are as early as 15:55. Given that the Earthquake began at 14:46, that leaves only 9 minutes from the first tremors until the tsunami was hitting the land. Regardless of how efficient you are at evacuation, I don't think that is sufficient time.

Hmm, 15:55-14:46 = 1h09min. Is there a typo somewhere?
Hmm indeed. Now I can't seem to find the report where I read the times, so it was either a typo, or it was me being wrong with math, something entirely possible as well.
In any case, evacution isn't something that can be organised that quickly, I think. They were damned one way or the other.

I specifically noted earlier in this thread that the Fukushima plant was designed with 7.2-7.3 quakes in mind, not a 9.0, which is orders of magnitude more powerful than any quake experienced in the region historically. What precisely do you think would survive a quake of that magnitude?
Also of course, as you have pointed out before, it survived the quake just fine. It was the tsunami that did this particular plant in.
So, even though an earthquake that was about 33 x 33 times more powerful than what it was designed to withstand hit it, it still got through rather unscathed. It was only after it was hit by a wall of water, that it got into some problems. And so far it seems they might even be able to control the current situation as well.
