everyone are happy and enjoyed celebrate this festival
The cherry blossom (sakura) is Japan's unofficial national flower. It has been celebrated for many centuries and holds a very prominent position in Japanese culture.
There are many dozens of different cherry tree varieties in Japan, most of which bloom for just a couple of days in spring. The Japanese celebrate that time of the year with hanami (cherry blossom viewing) parties under the blooming trees.
The most important factor in determining the blooming time of cherry trees is the geographical location. Basically, the milder the climate, the earlier the blossoms open.
On Japan's southern, subtropical islands of Okinawa, cherry blossoms open as early as January, while on the northern island of Hikkaido, they bloom as late as May. In most major cities in between, including Tokyo, Kyoto, and Osaka, the cherry blossom season typically takes place in early April.
Furthermore, the blooming time of cherry trees differs from year to year depending on the weather. If the weather during the months and weeks preceding the cherry blossom season is mild, blossoms will open early. If it is cold, blossoms will open later. From year to year, the start of the blooming season can vary by as much as two weeks.
