In Japan, irises are called “shōbu (菖蒲)” and symbolize protection, purity, and strength. They’re also associated with warding off evil. In Western culture, the iris often symbolizes wisdom, hope, and royalty. The fleur-de-lis, a stylized iris, is a well-known symbol in European heraldry.
Iris flowers have a unique structure with three upright petals called “standards” and three downward-hanging petals known as “falls.” These falls often have intricate patterns or a central fuzzy line called a “beard” in bearded irises.
The Mizumoto Park Iris Festival is a vivid celebration of nature, culture, and community. With thousands of irises in full bloom, traditional performances, scenic walks, and lively stalls—all set against Tokyo’s largest park—it’s a vibrant weekend getaway right in Katsushika. Whether you’re chasing blooms, snapping photos, or simply seeking serenity, this festival delivers. Pets were enjoying more. 46 years is going on the Festival.
