Mushi Okuri: Japan’s Ancient Insect Expulsion Festival
Imagine standing by the edge of a lush, green rice paddy at twilight. As the sun dips below the horizon, the chirping of crickets is overtaken by the sound of drums and flutes. Suddenly, a ribbon of fire ignites in the distance. Hundreds of villagers, holding flaming torches, form a procession winding through the fields, illuminating the night like a dragon of fire. This is Mushi Okuri, a hauntingly beautiful Japanese ritual designed to drive away crop-eating insects and bad spirits.
While modern agriculture relies on pesticides, Japan’s rural communities have preserved this centuries-old tradition, transforming it from a desperate prayer for survival into a breathtaking celebration of cultural heritage.
The Origins of the Ritual
The term Mushi Okuri translates literally to “sending off insects.” In the days before chemical pesticides, rice farmers were at the mercy of nature. An infestation of planthoppers or locusts could mean famine for an entire village. To combat this, communities turned to the spiritual realm.
The practice generally takes place in early summer (typically June or July), a critical time for rice seedlings. The core concept is simple yet profound: the use of fire and sound to startle pests and guide them away from the fields. Villagers carry taimatsu (pine torches), beating drums and ringing bells while chanting prayers. The fire attracts the insects, and as the procession moves toward the village borders or a river, the pests are symbolically and physically “sent off” to a world where they can do no harm.
While the ritual is practical in its intent, it is deeply rooted in Shinto animism, where every element of nature possesses a spirit. The insects are not just bugs; they are often viewed as manifestations of malevolent spirits or restless ghosts that must be appeased or expelled.
The Legend of Saito Sanemori
One of the most compelling stories associated with Mushi Okuri helps explain why the ritual is treated with such solemn reverence. It revolves around the tragic figure of Saito Sanemori, a samurai from the Genpei War era (12th century).
According to legend, Sanemori was an aging warrior fighting for the Taira clan. During a battle, he was riding through a rice paddy when his horse tripped over a rice plant’s stump. The stumble allowed his enemies to catch up and slay him. In his dying breath, Sanemori cursed the rice plants that led to his demise, vowing to transform into a pest and devour the crops forever.
It is said that he became the rice insect known as the Sanemori-mushi. In many regions, particularly around the Hokuriku area, the Mushi Okuri ritual is explicitly performed to appease the vengeful spirit of Sanemori. During the procession, you may hear chanters shouting, “Send off the Sanemori insect!” (Sanemori-mushi o oi-dase!). A straw doll representing the samurai is often carried at the front of the parade and cast into a river at the end, symbolizing his departure from the mortal realm.
Modern Culture and Preservation
Today, Mushi Okuri is less about pest control and more about community bonding and preserving intangible cultural heritage. While it was once performed in villages across Japan, it is now most famous in specific preservation districts, particularly in the Noto Peninsula (Ishikawa Prefecture) and parts of Shiga and Chiba prefectures.
Photographers and cultural enthusiasts flock to these events to capture the visual poetry of the fire procession. The sight of the glowing line of torches reflecting off the water in the rice paddies—known as mizukagami—is considered one of Japan’s original landscape marvels. The event serves as a reminder of the delicate balance between humanity and nature, a relationship defined by respect, fear, and gratitude.
In 2011, the Mushi Okuri ritual of the Noto Peninsula was designated as an Intangible Folk Cultural Property, ensuring that the drums and chants will continue to echo across the fields for generations to come.
Traveler’s Tips
If you wish to witness this magical event, planning is essential. Since Mushi Okuri is a local folk event rather than a national holiday, dates can vary slightly year by year based on the lunar calendar or local agricultural schedules.
- Best Time to Go: The rituals usually occur in June or July. The specific dates are often announced by local tourism boards a few weeks in advance.
- Key Locations: The most famous celebration is arguably the Sena Mushi Okuri in Kanazawa (Ishikawa Prefecture). Another excellent spot is the Tarumi district.
- Attire: You will be walking near rice paddies at night. The paths can be narrow, muddy, and dark. Wear sturdy boots or shoes you don’t mind getting dirty. Long pants are recommended to avoid mosquito bites.
- Etiquette: Remember that this is a spiritual event for the locals. While photography is usually welcomed (and the fire is incredibly photogenic), avoid using flash, as it ruins the atmosphere and can disturb the participants navigating dark paths with fire.
- Safety: You are watching a parade of open fire. Keep a safe distance from the torchbearers, especially if it is windy.
