The country is filled with beautiful cherry blossoms in spring. Visiting Japan during the cherry blossom season is a memorable experience. When do cherry blossom flower in Japan? Cherry blossoms (Higan zakura) normally begin blooming in January in Okinawa, and somei yoshino cherry blossoms reach their peak in late March to April in Honshu region. In Hokkaido, cherry blossoms are usually in full blooms in May.
However, it's really difficult to predict cherry blossom opening dates in advance, and planning a trip at the right time is tough. In Japan, the JWA (Japan Weather Association), the Weather Map Co., Ltd, and the Weathernews Inc. mainly announce cherry blossom forecasts every spring.
Please note that cherry blossom opening dates vary every year, depending on the weather condition. Once cherry blossoms open up, they usually reach their peak within 10 days. The blooming period of somei yoshino cherry blossoms is short.
