Konaki Sumo

A Heartwarming Japanese Tradition


2026/05/02

Every spring and autumn, the air around shrines throughout Japan is filled with the cries of babies and the laughter of families. "Naki Sumo" (Crying Sumo) is a unique and heartwarming festival where sumo wrestlers and shrine priests gently hold babies on a sumo ring and encourage them to cry, praying for their healthy growth and protection from evil. Famous venues include Imamiya Shrine in Kanuma, Tochigi, and Mikumano Shrine in Hanamaki, Iwate, each attracting crowds of parents and onlookers every year.

This event, with a history of over 400 years, draws thousands of participants and spectators from across the country annually. It's popular not only with families wishing for their children's health, but also with travelers seeking to experience authentic Japanese tradition and a warm, welcoming atmosphere.

Main Attractions

The Naki Sumo Match

The main highlight is the Naki Sumo match, where babies aged about 6 months to 1.5 years, dressed in tiny kesho-mawashi (sumo aprons), are held by sumo wrestlers or priests and encouraged to cry on the dohyo (sumo ring). The audience cheers with shouts of "Yoisho! Yoisho!" and the first baby to cry, or the one who cries the loudest, is declared the winner (though recently, all babies are often considered "winners"). The sound of crying, applause, and family smiles fills the shrine grounds, creating a warm and joyful atmosphere.

Other Events

Besides the main matches, there are Shinto rituals for health and harvest, performances of local arts, and commemorative photo corners. At Mikumano Shrine in Iwate, a national tournament is held, attracting participants from all over Japan and even overseas.

Costumes and Decorations

Babies wear little kesho-mawashi and red-and-white cords, while sumo wrestlers and priests are dressed in happi coats or ceremonial robes. The sumo ring is decorated with sacred ropes and banners, and the shrine grounds are filled with colorful flags, food stalls, and the scent of fresh greenery and incense.

Cultural and Historical Background

The origin of Naki Sumo lies in the old belief that a baby's strong cry can ward off evil and bring good health. At Imamiya Shrine, there is even a legend about a child brought back to life by the sound of crying. The custom dates back to before the Edo period in some regions. Over time, it has also come to include prayers for children's growth and first shrine visits, and is now a cherished annual event in many communities.

For local people, Naki Sumo is a rite of passage wishing for children's healthy growth and a traditional event that strengthens community bonds. In some areas, it is designated as an Important Intangible Folk Cultural Asset.
