What do you mean by "quakeproof"? Most newer buildings are built to fairly strict regulations, which is supposed to mitigate damage from earthquakes, but noone really knows exactly what will happen. In the two medium-sized quakes we have just had, nothing even fell over in my 4th floor apartment. This is a big city, and so if there is a very large earthquake, which might happen tomorrow, or 50 or 100 years from now, there will certainly be a lot of casualties.

Those of us who live in Tokyo live with this every day- you are just visiting. If you don't want to take your chances, then don't come. Keep in mind that the chances of you getting hit by a bus next time you cross a street are considerably higher than the chances of you dying in an earthquake.
