Been feeling a few small rumbles previously but they weren't too noticeable, felt kinda like a fat guy shaking his leg on the floor while sitting close by on bleachers.
This morning was a bigger one though, it woke me up from my sleep with the rumble of stuff shifting and shaking for a few seconds, nothing terribly long. I'm only on the 2nd floor of my building so it wasn't as bad as I imagine it would get higher up. Checked the earthquake logs online and seemed to be a 5.3 magnitude quake. Just another typical day in Japan, will probably feel more before I leave. Hopefully not a big Tokai quake though.
