Larger buildings tend to better withstand the large quakes. Building codes have been revamped after large quakes in Japan, so large commercial and public buildings tend to be the safest ones. They also are used for temporary shelter in natural disasters like quakes and heavy rain/typhoons.

Problem are with older wooden houses. There's quite a few photos and videos of older houses that have completely collapsed or their ground floors collapsing.

On a side note, since it's a public holiday, hospitals aren't able to cope with those who are injured because they're lightly staffed, and medical personnel can't reach them due to damaged roads, etc.
