On April 8, Japanese Buddhists celebrate Hana Matsuri (花祭) or Kambut(ts)u-e. It is dedicated to the birth of the Buddha, and is often referred to as the Flower Festival.
Celebrations dedicated to the birthday of the founder of one of the world's religions were known at the beginning of our era, although they gained popularity in the second half of the 19th century.
All ceremonial actions that take place on this day in Buddhist temples in Japan, as well as on the streets of cities and villages, in houses, one way or another, are connected with the legend that tells about the birth of Buddha. A brief summary of it boils down to the fact that Queen Maya, who saw a white elephant in a dream, received a message from the gods, which said that she would soon give birth to a son who would become Enlightened.
