wikipedia say: Hanami (花見, “flower viewing”) is the Japanese traditional custom of enjoying the transient beauty of flowers; flowers (“hana”) are in this case almost always referring to those of the cherry (“sakura“) or, less frequently, plum (“ume”) trees.[1] From the end of March to early May, cherry trees bloom all over Japan,[2] and around the first of February on the island of Okinawa.[3] The blossom forecast (桜前線, sakura-zensen) “cherry blossom front” is announced each year by the weather bureau, and is watched carefully by those planning hanami as the blossoms only last a week or two.
