Katsushika Iris Festival 2026 Tokyo

The Katsushika Iris Festival is an annual seasonal event held at Horikiri Iris Garden and Mizumoto Park in Tokyo’s Katsushika Ward.

Every year from late May to mid-June, over 14,000 colorful iris flowers bloom across the two venues, creating one of Tokyo’s most beautiful floral landscapes.

During the festival, visitors can enjoy traditional Japanese performances, local entertainment, cultural activities, food vendors, and special events suitable for families and travelers. Free shuttle buses operate between the festival venues and popular sightseeing spots including Shibamata Taishakuten Temple, Kanamachi Station, and Kameari Station.

The festival is held alongside the National Green and Flower Fair Katsushika, making it an excellent opportunity to experience nature, local culture, and seasonal beauty in Tokyo.
