Japan’s official cherry blossom spotters on Monday confirmed the first blooming of the country’s favorite flower, declaring the official start of the festive season in the Japanese capital

Cherry blossoms, or “sakura,” are Japan’s favorite flower and usually reach their peak in late March to early April, just as the country celebrates the start of a new school and business year. Many Japanese enjoy walking or picnicking under the trees.

The cherry blossoms that line the iconic Washington, D.C., waterfront are days away from reaching peak bloom, according to the National Park Service.
