The cultural festival that celebrates the arrival of spring in Japan is called Hanami. Hanami, which means "flower viewing," specifically refers to the tradition of enjoying the beauty of cherry blossom trees (sakura) as they bloom. This festival typically occurs in late March to early April, depending on the region and weather conditions. During Hanami, friends and families gather in parks to have picnics under the blooming cherry trees, appreciating the fleeting beauty of the blossoms. It symbolizes renewal and the transient nature of life, making it a deeply cherished tradition in Japanese culture.
