2026 Katsushika Iris Festival (Horikiri Iris Garden)

Approximately 200 varieties and 6,000 irises bloom at this famous Edo-era spot. Each variety bears a unique name, making it fun to appreciate the flowers and their labels. Evening illuminations are held during the festival. The garden's atmosphere, depicted in Hiroshige's ukiyo-e prints, is enchanting. Visiting both venues with Mizumoto Park is recommended.

Horikiri's fame as an iris-viewing spot dates back to the Edo period. During the Meiji era, multiple iris gardens such as Kodaka-en and Musashi-en flourished, reaching their peak in the Taisho era. The gardens were temporarily converted to rice paddies during wartime but were revived afterward. The current garden opened in 1959, and in 1971, the iris was designated as the official flower of Katsushika Ward through public vote. The site has been depicted in ukiyo-e by Hiroshige and Toyokuni.

About 10 minutes on foot from Horikiri Shobuen Station on the Keisei Main Line. Free shuttle buses run on weekends and holidays (5/30, 31, 6/6, 7, 13, 14) connecting Mizumoto Park, Shibamata Taishakuten, Kanamachi Station, and Kameari Station. Admission is free.

Weekends are crowded, so weekday mornings are recommended. The garden is compact, so navigating can take time during peak periods. Best viewing is from early to mid-June.

Admission is free. A rest area inside the garden offers coffee for 200 yen. The free shuttle bus (weekends/holidays only) is convenient for visiting both Horikiri and Mizumoto Park. Events such as taiko drumming and parades are also held near the station.
