Hanami ("flower viewing") is the Japanese traditional custom of enjoying the beauty of flowers; flowers ("hana") - in this case almost always referring to those as cherry (“sakura”).
From the end of March to early May, cherry trees bloom all over Japan.
Today in Japan, hanami mostly consists of having an outdoor party beneath the sakura during daytime or at night. These days, since the blossoming coincides with the beginning of the school year and financial year, it has become a more festive celebration with eating and drinking to the night.
The hanami celebrations usually involve eating and drinking, playing and listening to music beneath the beautiful trees in the companion of your family, friends and loved ones.
