In Japan, cherry blossom season is a special time of the year. People celebrate by having picnics under the cherry trees with their friends and family. This tradition is called hanami, which means "flower viewing." The season usually starts in March in the south and moves north as the weather gets warmer. Many parks and streets are full of pink and white cherry blossoms, and people take photos to remember the beautiful scenery. At night, some places have lights to make the trees look even more magical.
