Dogwood, Nosewater tree?

I stopped off at the town office carpark to take photos of the carp streamers they have hanging there. This was on the way from east school to North school, where I was to teach one lesson and have lunch. It rained heavily and there was thunder and lighning during lunch - with a brief blackout.

The dogwood trees are in bloom. When I got to North, the newspaper was on my desk with a picture of dogwood trees on the front. In Japanese, it's hanamizuki, which sounds like "nose water tree", though is really "flower water tree".
