Somin Shorai: The Legend Behind Japan’s Luck Charms
If you wander through the historic streets of Kyoto, particularly during the humid heat of July, you might notice a peculiar decoration hanging above the entrances of traditional machiya townhouses. These amulets, often shaped like octagonal prisms or wrapped in bamboo leaves, bear a cryptic inscription: Somin Shorai Shison Nari (“I am a descendant of Somin Shorai”).
To the uninitiated traveler, these appear to be simple souvenirs. However, they are powerful talismans rooted in one of Japan’s most enduring folklore tales—a story of humility, hospitality, and divine retribution that has protected households from plagues for over a millennium. Here is the fascinating history behind Somin Shorai.
The Origins of the Talisman
The story of Somin Shorai is distinct from the high mythology of the Imperial Court found in the Kojiki, yet it is deeply embedded in the Shinto practice of yakuyoke (warding off evil). The legend primarily originates from the Bingo no Kuni Fudoki (The Gazetteer of the Province of Bingo), a record dating back to the Nara period (710–794 AD).
Scholars believe the central deity in the story, often referred to as Mutou-no-Kami, is syncretic, sharing characteristics with Susanoo-no-Mikoto, the Shinto storm god. Over centuries, the specific practice of invoking Somin Shorai’s name evolved from a local folk belief into a major component of the Gion Festival, one of Japan’s most famous events.
The Legend of the Two Brothers
The folklore tells of a god traveling disguised as a weary, impoverished traveler. As night fell, he sought lodging in a village inhabited by two brothers: Kotan Shorai and Somin Shorai.
The Rejection and the Welcome
Kotan, the wealthier of the two, lived in a grand estate. When the disguised deity knocked on his door asking for a place to rest, Kotan turned him away, hoarding his wealth and refusing to share his comfort with a beggar.
Somin, on the other hand, was incredibly poor. Despite having barely enough food for himself, he welcomed the stranger into his humble, dilapidated hut. He offered the traveler a bed of millet straw and shared his meager meal of millet rice.
The Divine Reward
Touched by Somin’s generosity, the deity revealed his true form the next morning. Before departing, he warned Somin that a terrible plague would soon sweep through the land. He instructed Somin to weave a ring of茅 (chigaya or cogon grass) and wear it around his waist. He told Somin, “If disease spreads, declare that you are a descendant of Somin Shorai, and you shall be spared.”
True to the prophecy, a pestilence struck the village, wiping out those who had been selfish, including the wealthy Kotan. Only Somin and his family, protected by the grass ring and the god’s blessing, survived.
Modern Culture and the Gion Festival
Today, the legend lives on vividly, most notably through the Gion Festival centered around Yasaka Shrine in Kyoto. The festival originally began as a purification ritual to appease angry spirits causing plagues. The connection to Somin Shorai is central to the event’s spiritual purpose.
The Chimaki Amulet
During the festival, visitors purchase chimaki—spikes of bamboo leaves wrapped in straw. Unlike the edible chimaki found elsewhere in Asia, these are strictly decorative amulets. They almost always carry the phrase declaring the household as descendants of Somin Shorai. By displaying this, families essentially tell the gods of disease, “Pass us by; we are the good people, just like Somin.”
Chinowa Kuguri
In shrines across Japan, specifically during the Summer Purification (Nagoshi no Harae) in late June, you will see massive rings of woven grass set up in front of the main hall. This is the Chinowa. Worshippers walk through the ring in a figure-eight pattern to cleanse themselves of sins and impurities accumulated over the past six months. This ritual is a direct reenactment of the grass ring given to Somin Shorai.
Traveler’s Tips
If you want to experience this cultural touchstone yourself, here is how to incorporate it into your Japan itinerary:
- Where to Go: The most famous location is Yasaka Shrine in Kyoto. However, the legend is also celebrated at the Shinano Kokubunji Temple in Ueda City, Nagano, which holds a dedicated Somin Shorai Festival in January.
- When to Visit: To see the Chinowa (grass rings), visit a major Shinto shrine around June 30th. To collect the chimaki amulets, visit Kyoto during the Gion Festival (July 1st – 31st).
- Souvenirs: You can purchase Somin Shorai wooden charms (often hexagonal or octagonal) at various shrines year-round. They make for meaningful gifts representing health and protection.
- Etiquette: If you buy a charm, it is traditionally hung above the entrance of your home (inside or outside), visible to anyone entering, acting as a spiritual security system.
