Tachikawa's Showa Kinen Park isn't content with merely hyping sakura: its Flower Festival takes place over three months and celebrates the blooms of winter rapeseeds (in March), tulips (April), nemophilia (April-May), poppies and German chamomile (May), of course in addition to the cherry blossoms in March and April.
Along with flower-viewing, the park will be hosting a number of floral-themed events, and dedicated photo spots will be set up on the premises. Don't miss the chance to see a beautiful field of nemophila flowers in late April, which turn into a gorgeous sea of blue once 2 million nemophilia plants bloom at once.
