@tamegoeswild reported feeling the tremor from the nation's capital.
@tamegoeswild (Tokyo): Pretty long earthquake in Tokyo.
@tamegoeswild (Tokyo): earthquake was a 5.8 off the coast of Ibaraki http://tinyurl.com/4q35uc
Apparently not all from Tokyo felt the quake, however.
@modernangel76 (Tokyo): @tamegoeswild I sleep through every earthquake and rarely feel the ones I am awake for. In 1.5 years I have only felt one.
