Japanese folklore

• 1. Introduction

  ›

  Japanese folklore reaches back through centuries of oral tradition, sacred ritual, and handcrafted objects, binding together a people whose customs range from towering pilgrimage routes to tiny kitchen altars. On the Oga Peninsula in the Northeast region of Japan, men still don ogre-like masks and traditional straw capes called mino, then move through neighborhoods in an annual ritual. They are the Namahage, masquerading as kami, the divine spirits of the Shinto tradition, and their purpose is to instill fear in children who have been lazily idling by the fire. That image, frightening and festive at once, opens a window into a tradition that is practical, sacred, and often surprising in equal measure. What are the creatures that haunt these stories? Who preserved them, and why do some rituals refuse to be photographed? How did an eighteenth-century author come to be called the Perrault of Japan? Those are the threads this documentary will follow.

• 2. Sacred Practice and Folk Religion

  ›

  On the Yaeyama Islands of Okinawa, a ritual parallel to the Namahage ceremony is kept alive under strict conditions: it does not allow itself to be photographed. That secrecy points to something important about Japanese folk religion, which has always maintained a double life, part public spectacle and part guarded inheritance. Many households, though increasingly fewer, maintain a kamidana, a small Shinto altar shelf placed in the home. The kitchen holds its own sacred presence. Shinto households honor a kitchen god known by a specific name; syncretic Buddhist households instead enshrine the Kōjin, a deity of the hearth, in the same domestic space.

  Popular cults called kō sometimes gather around particular deities, such as the fierce Fudō Myōō or the healing Yakushi Nyorai. Others are organized around sacred sites rather than figures. The Ise Shrine draws its own cult, Ise-kō, and Mount Fuji has inspired the construction of many local mock-Fuji shrines across the country. Pilgrimage to major sites like these declined after the Edo period, but the Shikoku Pilgrimage, a circuit of eighty-eight temple sites commonly called ohenro-san, has more recently become fashionable again, with popular media and cottage industries promoting its shrines.

  Everyday protective customs are just as varied. In some areas, a small mound of salt placed outside the house is thought to repel ill fortune. Salt scattering more broadly is considered purifying; sumo wrestlers scatter it across the ring before a match. Period dramas still stage a standard scene in which a householder orders salt scattered after an unwanted visitor leaves. On the opposite end of the spectrum, striking sparks with flint as someone departs was considered lucky. Sounding drums, avoiding certain directions, and interpreting the layout of a house through a practice similar to Feng Shui, known literally as "house physiognomy," all belong to the same network of daily protections.

  From China, through the system called Onmyōdō, Japan inherited a form of geomancy that assigned danger to the northeast. The word for "ogre's gate" originally described that unlucky northeasterly direction, thought to invite ill-intended spirits. A widely known taboo holds that sleeping with the head pointed north brings misfortune, though the practice is rarely observed strictly today. The Kōshin cult, now largely inactive, was once associated with a required silent vigil; it is also the cult linked to the iconic three monkeys who see, hear, and speak no evil.

• 3. The Lives of Folktales

  ›

  A folktale in Japan typically opens with the word "Mukashi," functioning as a spoken equivalent of "Once upon a time," and closes with a set phrase such as "dotto harai" or its variant "Dondo Hare." These tales were called mukashi-banashi, meaning stories of "long ago" or from "bygone times," and they circulated in local dialects that outsiders often found hard to follow, partly because of differences in intonation and pronunciation, partly because of conjugations and vocabulary that shifted from region to region.

  When folklorists collected these stories from the field, the versions they recorded were often adaptations, not strict transcriptions. Multiple collected versions would be merged into a single standard Japanese text. Classic tales like Momotarō, which most Japanese people today encounter through picture books, manga, or other popularizations, can be traced to picture-books printed in the Edo period, though their origins likely run much deeper. The children's story author Sazanami Iwaya, who lived from 1870 to 1933 and is often called the Perrault of Japan, played a significant role in setting down the forms of these tales that are most widely recognized today.

  Two creatures dominate the shape-shifting world of Japanese folktales: the kitsune, or fox, and the tanuki, the Japanese raccoon dog. Both are known for their ability to transform into humans, other beings, and objects. One famous tanuki named Bunbuku Chagama could shapeshift into a teapot. Stories about marriages between humans and non-human beings form a major category in the tradition. The crane story describes a sustained period of married life between a human and a crane, unlike Western counterparts such as the Frog Prince or the Leda myth, where the supernatural encounter is brief. An unusual pairing appears in the tale of a bride wedded to a tiny tanishi, a river snail; this story exists in both a polished written version and a more rustic oral form.

• 4. Stage, Adaptation, Craft

  ›

  Playwright Junji Kinoshita brought several folktales to the stage, most notably Yūzuru, known in English as Twilight Crane, staged in 1949. It drew on the folktale Tsuru no Ongaeshi, the story of a crane who repaid its gratitude to a human. Kinoshita's adaptation is one of the clearest examples of how folk material moved from oral tradition into formal theatrical performance, preserving the emotional logic of the original while giving it a new stage life.

  Folk craft occupied a parallel world of preservation and revival. Objects of daily household use, accumulated by Keizo Shibusawa, became the Attic Museum collection, which is now mostly housed in the National Museum of Ethnology in Suita, Osaka. The Mingei movement, spearheaded by Yanagi Sōetsu, argued that folk craft deserved appreciation on aesthetic grounds, not just as ethnographic data. Well-known craft objects like netsuke and Shigaraki ware raccoon dog earthenware fall along the line between traditional craft and folk art.

  Folk painting called Ōtsu-e was produced in Ōtsu in Shiga Prefecture, often depicting ogre-like figures, and sold as amulets for travelers. Ema are wooden plaques painted with horses or other figures, onto which worshippers write wishes before hanging them at shrines. Koinobori are carp-shaped banners. Among toys, the Akabeko is a red papier-mâché bull or cow with a bobbing head; the Okiagari-koboshi is a legless, bottom-loaded doll that always rights itself after being knocked over. The three major wooden carved horse figurines come from distinct regions: Miharu-goma from Fukushima Prefecture, Yawatauma from Aomori Prefecture, and Kinoshita-goma from Miyagi Prefecture.

• 5. Cloth, Costume, and Creatures

  The straw cape called mino, worn by the Namahage on the Oga Peninsula, was not ceremonial in origin. It was everyday rain gear and snow gear, woven from rice straw. Snow boots were made from the same material. The waraji, also straw-woven, served as footwear. The kasa, a hat woven from sedge, soft rush, strips of bamboo, or strips of hinoki cypress, protected travelers and workers from the elements. In Yamagata Prefecture and other regions, the bandori, a type of often colorfully woven back strap, was used when carrying loads. Kogin-zashi, from Aomori Prefecture, is a form of quilted clothing with distinctive patterned stitching.

  Many of the creatures that populate Japanese folktales, the yōkai, or demons, circulated through the same oral channels as the clothing customs and kitchen altars. Some yōkai are genuinely folkloric, passed through communities without a named author. Others were deliberately invented by professional writers during the Edo period and earlier; they look folkloric but are literary creations. Pheasants carry a different kind of weight in traditional belief. In Japanese folklore, pheasants were considered messengers from heaven. Researchers from Japan's Graduate University for Advanced Studies and the National Institute of Polar Research proposed in March 2020 that red pheasant tails described across the night sky over Japan in 620 A.D. may actually have been a red aurora produced during a magnetic storm, a natural phenomenon that ancient observers encoded in the language of sacred birds.
