There are some cherry blossoms which bloom during February, too.
Some are more colorful than the ones that bloom in March in order to attract birds' and insects' attention to have their pollens carried.
This is a tree of Kanzakura, which means the sakura which blooms when it's cold, in Ueno Park.
I also like the one that blooms in the middle of February named Tsubakikanzakura, originally comes from Shikoku, at the East Gardens of the Imperial Palace. The Japanese love Sakura so much that you can see some kinds of sakura except Summer, from June till September, even though many Japanese don't know that fact.
It's easier to book the hotels than April, so please come. I'll be looking forward to seeing them together with you.
