The seasonal event is ready now in Tokyo and generally it will be the best for viewing in one week or 10 days. 🙂
By the way, do you know why cherry blossoms, Somei-Yoshino or Sakura in Japanese, tend to blossom at the same time and then the petals fall off in synch?
Most cherry trees planted are by PEOPLE, not natural placements, so,, as a result, they are related to each other sharing the same DNA.
Enjoy your trip!
