Beneath the sumo ring lies Shizumemono (鎮物, “shizumemono”), a set of seven sacred offerings. These items are dedicated to the gods, praying for the safety of wrestlers, their victories, and the prosperity of the people. This hidden ritual transforms sumo from a simple sport into a deep cultural and spiritual experience.

The Meaning of Shizumemono

In sumo, Shizumemono (鎮物, pronounced “shizumemono”) refers to the sacred offerings buried in the center of the ring (dohyō). These are not mere decorations but part of an ancient Shinto ritual passed down for centuries. The dohyō is considered a sacred space where deities descend, and burying offerings there is a way of showing gratitude to the gods while praying for the safety of wrestlers, the well-being of the audience, and the prosperity of the nation.

This act also carries the meaning of purifying the ring itself. While modern audiences often see sumo as a sport, at its core it remains deeply religious, and Shizumemono symbolizes this spiritual foundation.


The Seven Sacred Items of Shizumemono

Shizumemono consists of seven types of auspicious offerings. Each has symbolic meaning rooted in Japanese culture and nature.

ItemSymbolic Meaning
RiceSymbol of life and abundance, praying for a good harvest
Kombu (kelp)Wordplay on “yorokobu” (joy), representing prosperity and happiness
ChestnutKnown as “kachi-guri” (winning chestnut), a prayer for victory
Nut of the kaya treeBelieved to ward off evil and protect from disasters
Dried squidSymbol of prosperity and longevity, as it keeps well
Victory chestnutStronger symbol of triumph for wrestlers
SaltRepresents purification and protection against evil spirits

Although hidden beneath the soil, these offerings serve as a silent prayer sustaining every match fought above them.


History and Origins of Shizumemono

The tradition of Shizumemono originates from jichinsai (ground-pacifying rituals) of ancient Japan. Before constructing buildings, people buried offerings such as rice, sake, and fish to calm the local deities and protect the site. Because sumo began as a ritual dedicated to the gods, the dohyō itself came to be treated as sacred, and this practice was adopted.

Even after sumo spread as popular entertainment during the Edo period, this ritual was preserved. Its continuation into the present day demonstrates that sumo is not merely a contest of strength but a cultural act of devotion to the divine.


Shizumemono and the Dohyō Ceremony

Shizumemono is buried during the dohyō matsuri (ring consecration ceremony) held before each tournament. Referees (gyōji) and Shinto priests dig a small hole at the center of the ring, place the offerings inside, and then mark the spot with sacred sakaki branches and ritual paper streamers (gohei). The entire ring is purified with rice and salt.

This ceremony, often open to the public, allows spectators to witness the spiritual foundation of sumo before the excitement of the matches begins.


Difference Between Shizumemono and Purifying Salt

Spectators are most familiar with the act of wrestlers throwing purifying salt before their bouts, but it should not be confused with Shizumemono.

Both practices share the themes of purification and prayer, complementing each other as the spiritual and ritual balance of sumo.


Shizumemono’s Appeal to Foreign Spectators

For foreign visitors, the idea of burying offerings beneath a sports arena is unusual and fascinating. Shizumemono reveals that sumo is not only a contest of physical strength but also a cultural and spiritual ritual.
