Japan in Cherry Blossom Season While Japan is beautiful year-round, the few weeks each spring when cherry trees across the country explode with blossoms is a particularly pretty time to visit. Cherry blossoms usually bloom between mid-March and early May. In 2022, Tokyo's cherry blossom season officially began on March 20, when flowers opened on a Somei-Yoshino cherry tree at Yasukuni Shrine. While the dates change somewhat from year to year, there are areas in which cherry blossoms bloom even earlier!
