Here in Tokyo (Narita), it was just a little shake that lasted for about 20 seconds or so. It was so mild, I had to ask my partner "Did you feel that?" I imagine it was more severe in Hokkaido, but I haven't heard reports of any significant damage. The predicted three metre-high tsunami was only about 50cm.

Here we go again - confusing correlation with a causal relationship. Maybe soaking in a hot tub five times a week helps people relax and that's why they live longer. I'm sure the oily fish they eat helps a lot too.
