I was at a NRT hotel this past March ~ 1 year after the big 2011 quake and all of a sudden noticed my water bottle shaking on the table and then the whole room shaking. Turned out to be 4 something on the Richter scale and fortunately no damage but I kept worrying it was another big one and that there might be runway damage for my flight back the next day. Was fortunate to get out in F.
