Showa Kinen Park

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.

Showa Kinen Park is the most beautiful in autumn, with the maple and ginkgo trees blushing in fiery red and yellow respectively. The ginkgo trees are the first to turn and you can see two boulevards of the golden yellow trees as soon as you enter the park’s Tachikawa gate. These trees are expected to turn full yellow in mid-November. The momiji and kaede trees, however, present their signature vermillion hues a bit later towards the end of November. During this season, the park stays open after dark, with special light-ups taking place at the Gingko Tree Avenue (near the futsal and basketball courts) and the traditional Japanese Garden from 4.30pm until 8.30pm. While you can enjoy the light-ups at Gingko Tree Avenue with just the park's regular admission fee (¥450, free for junior high school students and younger), you need an extra ticket to enter the Japanese Garden (advance ticket online ¥1,200, primary and junior high school students ¥600; same-day tickets sold at Komorebi House close to the Japanese Garden ¥1,300, ¥700). Tickets to enter the Japanese Garden are now available for purchase online, including park admission and Japanese Garden bundle pass for a discounted price of ¥1,600 (¥600). Admission into the Japanese Garden is waived on October 30 and 31.
