Ah. I should have been more specific.
I'm trying to coordinate my Tokyo visit to the first weekend of cherry blosssoms for a friend's Hanami party. Last year, when I was out there for the A's/Red Sox MLB opener, the flowers bloomed early, Hanami wound up that weekend (instead of the date it was forecast for) and I had to leave

the Thursday before. Missed it by TWO DAYS!!! Grrr!
So that's why I'm trying to find a proper window to do this visit in...
