While less well-known than sakura, cosmos are also a beloved flower in Japan and the symbol of early autumn. The five gardens below, which are within or near the Tokyo Metropolitan area, are all blessed with beautiful fall scenery, replete with fields of quintessential cosmos flowers.

Introduced to Japan during the Meiji period (1868-1912), cosmos or akizakura, translating literally to “fall cherry blossoms,” are one of the most well-known autumn flowers. They are popular for their bright orange, yellow and most commonly, pink and magenta blooms. Originally from Mexico, cosmos made their way to Spain at the end of the 18th century. There, they were named “cosmos” because of their orderly overlapping petals which reminded explorers of the Greek word “kosmos” meaning “order,” “world” and “harmonious arrangement”. Japan fell in love with this fall beauty and now has cosmos gardens in Tokyo dedicated to presenting their loveliness as the weather cools down.

Indeed, viewing vast fields of these tall delicate flowers swaying in the breeze will surely inspire the photographer in you to visit the parks below to catch a snapshot of their harmonious seasonal beauty.
