This was the biggest earthquake for me so far. It began slowly, then building up until the house shook so much that the structure creaked. Then passing away, but with noticeable sways for some more minutes.
Epicenter was in Ibaraki, the prefecture just north of Tokyo. So many Tokyo wards, including central Shibuya, got intensity 3; “some people are frightened”. My own ward, Suginami-ku, only got a 2: “Homes and apartment buildings will shake, but will receive no damage.”
Though I must say it looks on the map like Suginami got a 3, and to be honest I got a bit frightened too!
