Sakura originally was used to divine that year's harvest as well as announce the rice-planting season.
People believed in kami inside the trees and made offerings.
Usually, people go to the parks to keep the best places to celebrate hanami with friends, family, and company coworkers many hours or even days before.

C., the arrival of spring brings a splash of color as the city’s iconic cherry trees burst into bloom.
The city has enjoyed cherry blossoms each year dating back to 1912, when Japan gave about 3,000 cherry trees to the United States as a gift of friendship.
As the Leaf and Bloom Dates indicator explains, scientists have very high confidence that recent warming trends in global climate are causing spring events such as leaf growth and flower blooms to happen earlier.In the case of Washington’s cherry blossoms, earlier bloom dates could affect tourism and the local economy.The peak bloom date for the most common type of cherry tree around Washington’s Tidal Basin—the Yoshino variety—has been carefully estimated and recorded since 1921 by the National Park Service.Hanami at night is called yozakura (夜桜, "night sakura").In many places such as Ueno Park, temporary paper lanterns are hung to have yozakura.Hanami was first used as a term analogous to cherry blossom viewing in the Heian era novel The Tale of Genji.Although a wisteria viewing party was also described, the terms "hanami" and "flower party" were subsequently used only in reference to cherry blossom viewing.Poems would be written praising the delicate flowers, which were seen as a metaphor for life itself, luminous and beautiful yet fleeting and ephemeral. The custom was originally limited to the elite of the Imperial Court, but soon spread to samurai society and, by the Edo period, to the common people as well.Tokugawa Yoshimune planted areas of cherry blossom trees to encourage this.It also shows the dates of the National Cherry Blossom Festival, which has grown to several weeks as its popularity has expanded.There is considerable variability in the peak bloom date, which makes predicting the exact timing difficult.
