The blossoming of sakura (cherry blossoms) is an occasion for celebration all over Japan. Between late March and early April, families, friends and colleagues come together for ohanami or “blossom-viewing” parties, picnicking, drinking and even singing karaoke in the city’s public parks beneath the riotous pink blossoms.
Part of the magic of sakura is that you never know for certain when they’ll start to bloom or be in full bloom. To help you plan your ohanami with better probability, refer to this website which offers updated forecast for sakura all around the country.
