Tachikawa's Showa Kinen Park has the most impressive fields of cosmos flowers in Tokyo and this is the ideal time to see them all in full bloom. The hilly grasslands of the park are usually draped in colour from mid-September with various types of cosmos flowers, and the multicoloured scenery can be enjoyed well into mid-October.
There are three main gardens: The Lemon Bright field, which is covered in vivid yellow sulfur cosmos; Autumn Bouquet Garden, which has a mixture of 20 different cosmos; and the Cosmos Sensation filled with lilac blooms.
Don't miss the picturesque soap bubble event, where you can see countless small bubbles floating over the flower gardens. This special spectacle happens twice a day from 10.30am and 12noon on September 13 at the Lemon Bright field, September 28 at the Autumn Bouquet Garden, and October 4 at the Cosmos Sensation flower garden.
Entrance fees are waived on October 5 and 19, 2025.
