Cherry Blossom Forecast 2007
| Full bloom is approaching or has already been reached in several cities across Japan. The trees are a few days ahead of their average schedule due to an unusually warm winter (1-3 degree above average in most parts of Japan). Below are the forecast/actual dates of cherry trees opening their blossoms this year (according to the Japan Meteorological Agency) and the estimated best viewing periods (estimated by japan-guide.com). Rain, wind and temperatures can have a strong effect on the process of the season, for example, they can delay or shorten it considerably. Therefore, use the forecasts on your own risk. | ||||||||||||||||||||||||||||||||||||

When do they bloom?
The most important factor that determines 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 Hokkaido, they bloom as late as May. In most major cities in between, including Tokyo, Kyoto and Osaka, the cherry blossom season typically takes place around the end of March and beginning of April (see table below).
Furthermore, the blooming time 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 plus/minus two weeks.
How long do they bloom?
The cherry blossom season is relatively short. Full bloom (mankai) is usually reached within about one week after the opening of the first blossoms (kaika). Another week later, the blooming peak is over and the blossoms are falling from the trees. Strong wind and rain can cut the blooming season even shorter.
Cherry blossom forecasts
Every year, the Meteorological Agency and the media is closely following the so called "cherry blossom front", as it slowly moves northern wards. Note, that the front indicates the opening of the first blossoms (kaika) rather than the arrival of full bloom (mankai).
Of course, not every tree in a city opens on the same day, as trees in shadowy places, for example, bloom several days later than trees in sunny places. That is, why a set of representative sample trees is selected to define the date of kaika (the opening of the first blossoms) for a whole city. In Tokyo, the sample trees are located at Yasukuni Shrine.
Average blooming dates
The dates below indicate the average dates on which cherry trees open their first blossoms for selected cities, and the dates on which they opened in the previous two years. Remember that full bloom is usually reached within about one week from the date the first blossoms have opened.
