Cherry blossom front

The cherry blossom front (桜前線, sakura zensen) is the advance of the cherry blossoms across Japan. The Japan Meteorological Agency records the opening and full bloom of the blossoms from Kyūshū in late March to Hokkaidō in the middle of May. The advancing front is also the subject of regular reports by the major news agencies. The cherry blossom is of great public interest in Japan due to its symbolism and the custom of flower viewing known as hanami.
