Guide
Mizudome-no-mai is a deeply historical traditional performing art passed down in Ota City, Tokyo. Its origins date back to 1321 (the first year of the Genko era), and it has been carefully preserved by the local community for approximately 700 years. As a designated Tokyo Intangible Folk Cultural Property, it serves as a precious symbol of Japan's traditional ritual culture. The performers' vibrant costumes and the unique, striking design of the lion masks transport spectators into a mystical, otherworldly realm.
The ritual's origin lies in a severe drought that struck the Musashi province (modern-day Kanto region). In 1321, it is said that when the second high priest, Fomitsu, offered prayers to a dragon statue made of straw, rain finally fell. However, two years later, the region suffered from excessive rainfall, causing fields to wash away. While some blamed the priest for the heavy rain, he addressed the crisis by creating three lion masks. He had performers wear the masks, beat drums, and blow conch shells to perform the "Mizudome" (stopping the water) prayer, which successfully calmed the rains. Today, the ritual is performed as a traditional dance of gratitude rather than a strictly religious prayer.
The greatest appeal lies in the visual impact and the mystical structure of the ritual. Performers wear large red or black headcoverings that completely mask the face, adorned with vibrant artificial flowers in pink, yellow, blue, and red. The combination of geometric patterned kimonos (blue and white scale patterns), the rhythmic beat of the drums, and the resonant sound of the conch shells creates a powerful, unique atmosphere. The blend of traditional attire, vigorous movements, and profound sounds offers a deeply moving experience for all observers.
Mizudome-no-mai is a special event held only on the second Sunday of July each year. The ritual takes place from 1:00 PM to 3:00 PM, allowing visitors to feel the intense energy of a traditional Japanese summer-themed event. While the ceremony proceeds even in rain, the outdoor setting means the atmosphere may change with the weather. For travelers visiting Japan in the summer, this is a rare opportunity to witness a seasonal cultural treasure.
As an observer, you can deeply appreciate the movement, sound, and historical weight of the performance. Watching the performers wear the lion masks while playing the drums and conch shells is a direct encounter with the embodiment of Japanese spiritual culture. While not a participatory activity, witnessing this centuries-old form of "prayer" alongside the local community is a profoundly valuable cultural experience.
The venue is Gonsho-ji Temple located in Omori Higashi, Ota City. The surrounding area offers further cultural exploration, such as the "Omori Nori no Furusato-kan" (Nori Seaweed Museum). The location is relatively easy to access from central Tokyo via bus from Keikyu or JR stations.
Since the ritual is held in July, it is highly recommended to wear breathable clothing and bring items for heatstroke prevention, such as water and a hat. As this takes place within a temple's sacred grounds, please be mindful of your surroundings. When photographing, ensure you do not obstruct the view of other worshippers or the performers. While the event is generally free to watch, please check local conditions for any updates.
