Sakura

  
      A cherry blossom is the flower of any of several trees of genus prunus, particularly the Japanese Cherry, Prunus Serrulata, which is sometimes called sakura after the Japanese.

      "Hanami" is the centuries-old practice of picnicking under a blooming sakura or ume tree. The custom is said to have started during the Nara Period (710–794) when it was ume blossoms that people admired in the beginning. But by the Heian Period (794–1185), cherry blossoms came to attract more attention and hanami was synonymous with sakura. From then on, in tanka and haiku, "flowers" meant "sakura." The custom was originally limited to the elite of the Imperial Court, but soon spread to samurai society and, by the Edo period, to the common people as well. Under the sakura trees, people had lunch and drank in cheerful feasts.

      Every year the Japanese Meteorological Agency and the public track the sakura zensen (cherry blossom front) as it moves northward up the archipelago with the approach of warmer weather via nightly forecasts following the weather segment of news programs. The blossoming begins in Okinawa in January and typically reaches Kyoto and Tokyo at the end of March or the beginning of April. It proceeds into areas at the higher altitudes and northward, arriving in Hokkaido a few weeks later. Japanese pay close attention to these forecasts and turn out in large numbers at parks, shrines, and temples with family and friends to hold flower-viewing parties. Hanami festivals celebrate the beauty of the cherry blossom and for many are a chance to relax and enjoy the beautiful view. The custom of hanami dates back many centuries in Japan: the eighth-century chronicle Nihon Shoki records hanami festivals being held as early as the third century CE.

      Most Japanese schools and public buildings have cherry blossom trees outside of them. Since the fiscal and school year both begin in April, in many parts of Honshu, the first day of work or school coincides with the cherry blossom season. The Japan Cherry Blossom Association developed a list of Japan's Top 100 Cherry Blossom Spots with at least one location in every prefecture.
