Hanami, or cherry blossom viewing parties, are an ancient Japanese custom for enjoying the arrival of spring when the cherry trees enter into full bloom. Every spring, usually in March or April depending on the climate, large groups of people can be seen in parks spreading out leisure sheets under the cherry trees, sharing food and playing games while viewing the pink blossoms. Nighttime Hanami is also very popular, when the white and pink petals, or “Yozakura,” show up clear and beautiful against the late-night illuminations, creating a different atmosphere from that of daytime.
