During this festival, people gather under the cherry trees with family and friends, enjoying food and drinks while admiring the blossoms, a true pleasure in life.

Cherry blossoms have a history of over 1,000 years in Japan. By the Heian period (794-1192), cherry blossoms took center stage, with songs about cherry blossoms outnumbering those about plum blossoms by fivefold. Japan started cherry blossom viewing activities quite early.

In the 7th century, Emperor Tenmu had a special fondness for cherry blossoms and often visited Yoshino Mountain in Nara to appreciate them. The first recorded cherry blossom viewing party in Japanese history was reportedly held by Emperor Saga in the 9th century.

Initially, cherry blossom viewing was popular among the nobility, but by the Edo period (1603-1867), it had spread to the common people, forming a traditional folk custom.

The life of a cherry blossom is fleeting. A Japanese proverb says, “Cherry blossoms last seven days,” meaning a cherry blossom lasts about seven days from bloom to wilt, and a whole tree lasts about 16 days, creating a characteristic of cherry blossoms blooming and falling simultaneously.

This characteristic is what makes cherry blossoms so enchanting. As the national flower, the cherry blossom is revered not just for its stunning beauty, but also for its “heroic” nature of blooming brilliantly and then promptly withering. “

Ask about the Japanese spirit, look at the cherry blossoms under the morning sun.” The Japanese believe that life is short and one should live brilliantly like a cherry blossom.

Even in death, one should leave decisively. When cherry blossoms fall, they are clean and unblemished, a symbol of the Japanese spirit.
