Tokyo was only hit by a 5-, i got a 4 here in Totsuka. Really it was just a matter of waking up to see if it was a big one, it wasnt, back to sleep :-)
The quake was a 6.2 in magnitude while the intensity felt in Tokyo was 5- as you said.
you are correct i was meant to mention that. interrupted sleep and all and pre-coffee replying haha.
