Japanese folklore

Men dressed as namahage, wearing ogre-like masks and traditional straw capes (mino) make rounds of homes,[1] in an annual ritual of the Oga Peninsula area of the Northeast region. These ogre-men masquerade as kami looking to instill fear in the children who are lazily idling around the fire. This is a particularly colorful example of folk practice still kept alive.

A parallel custom is the secretive Akamata-Kuromata ritual of the Yaeyama Islands, Okinawa which does not allow itself to be photographed.[2][3]

Many, though increasingly fewer households maintain a kamidana or a small Shinto altar shelf.[4] The Shinto version of the kitchen god is the Kamado kami (かまど神), and the syncretic Buddhist version is the Kōjin, a deity of the hearth enshrined in the kitchen.

Japanese popular cults or kō (講)[5] are sometimes devoted to particular deities and buddhas, e.g. the angry Fudō Myōō or the healer Yakushi Nyorai. But many cults centered around paying respects to sacred sites such as the Ise Shrine (Ise-kō or okage-mairi) or Mount Fuji (Fuji-kō, by which many local mock-Fuji shrines have been erected). Pilgrimage to these meccas declined after the Edo period. But recently, the Shikoku Pilgrimage of the eighty-eight temple sites (commonly known as ohenro-san) has become fashionable. Popular media and cottage industries now extoll a number of shrines and sacred natural sites as power spots.

There is a long list of practices performed to ward evil (yakuyoke (厄除け))[6] or expel evil (yakubarai, oharai (yaku-barai)), e.g. sounding the drums.[6] In some areas it is common to place a small mound of salt outside the house (morijio).[7][8] Salt-scattering is generally considered purifying[7] (it is employed in sumo tournaments,[7] to give a well-known example). A stock routine in period or even contemporary drama involves a master of the house telling his wife to scatter salt after an undesirable visitor has just left. Contrarily, lighting sparks with flint just as a someone is leaving the house was considered lucky.

No one now engages in the silent vigil required by the Kōshin cult, but it might be noted that this cult has been associated with the iconic three See no evil, hear no evil, speak no evil monkeys.[9]

There are certain vestiges of geomancy introduced into Japan from China through Onmyōdō. The word kimon, "ogre's gate", colloquially refers to anything that a person may have constant ill luck with, but in the original sense designates the northeasterly direction, considered to be unlucky or dangerously inviting of ill-intended spirits[9] (cf. Konjin). There is also a Japanese version of Feng Shui known as kasō[10] or literally "house physiognomy". Closely connected is the Yin-yang path or Onmyōdō, and its concepts such as katatagae also known as kataimi,[11] which was widely practiced by nobles in the Heian period. A widely known taboo (kitamakura) advises against sleeping with your head faced north,[12] though it is doubtful if anyone now seriously heeds this prohibition.[12]

In Japanese folklore, pheasants were considered messengers from heaven. However, researchers from Japan’s Graduate University for Advanced Studies and National Institute of Polar Research claimed in March 2020 that red pheasant tails witnessed across the night sky over Japan in 620 A.D., might be a red aurora produced during a magnetic storm.[13]

As in most developed nations, it is increasingly difficult to find living storytellers of oral tradition. But there is a wealth of folktales collected through the ages. The name mukashi-banashi (tales of "long ago" or from "bygone times") has been applied to the common folktale, since they typically open with the formula "Mukashi..."[14] (akin to "Once upon a time..."). They also close with some set phrase like "dotto harai"[14] (a variant form being Dondo Hare).

These tales had been told in their local dialects, which may be difficult to understand to outsiders, both because of intonation and pronunciation differences, conjugations, and vocabulary. Many folktales collected from the field are actually "translations" into standard Japanese (or more like adaptations, merging several collected versions).

Fantastic creatures

For monsters and ghostly creatures in general, see Yōkai. For horror or ghost stories, see Kaidan.

A great deal of interest currently gravitates towards Japanese monsters taken from traditional Japanese sources. Some of the yōkai or strange beings are the stuff of folklore, orally transmitted and propagated among the populace. But one must realize that many beings or stories about them were spun and deliberately invented by professional writers during the Edo Period and earlier, and they are not folkloric in the strict sense.

Some well-known craft objects such as netsuke, raccoon dog earthenware (Shigaraki ware), may be classed as traditional Japanese crafts.

A number of articles of daily household use (mingu (民具)), amassed by Keizo Shibusawa, became the Attic Museum collection, now mostly housed in the National Museum of Ethnology in Suita, Osaka. The Mingei movement spearheaded by Yanagi Sōetsu sought to appreciate folk craft from an aesthetic viewpoint.
