Ema (Shinto)

In some early Shinto and folk traditions of Japan, horses were seen as carrying messages from the kami, and were usually used to transmit requests during droughts or famines.[1]^: 27 Horses were extremely expensive, and figures made of clay or wood have been found dating to the Nara period.[1]^: 27 The earliest text record of a substitution is from the Honcho Bunsui from 1013, in which an offering of three paper horses is made at the Kitano Tenjin shrine.[1]^: 27 During the Kamakura period, the practice entered into Buddhist practice, as evidenced in painted scrolls of ema at Buddhist temples.[1]^: 30

The depictions of objects aside from horses can be traced to either the Muromachi or Tokugawa periods, beginning with larger sized ema (named ōema, literally 'large ema') but also representing new forms, such as ships. Artists of this period, such as Hokusai, began to create ema in distinct styles, and creating the objects became a professionalized craft.[1]^: 30

Today, they are mostly produced at or by the shrine or temple in which they are found.[1]^: 31 Some shrines have faced criticism for profiting from the sale of ema. In 1979, two shrines dedicated to education sold ema for examination success, transforming the funds into a scholarship in 1980 after public outcry.[3]^: 50

Historically, groups of farmers or small merchants could organize to hire a local artisan to create an ema to be donated to a shrine for a specific purpose, such as a good harvest.[4]^: 257 Archeological records suggest this could have been used to send political signals, as in the case of a Fukuoka Prefecture shrine that saw an increase in commissioned portraits depicting peaceful relations with Korea amidst tensions between the nations during the late 19th century.[4]^: 260

Ema can represent deities, such as Kannon and Jizō, but also more specific iconography depending on their intended purpose. These include depictions of a phallus or breasts for fertility prayers, or an octopus representing the desire to be cured of warts.[1]^: 31 Another example are sandals depicted on plaques for foot remedies.[2]^: 158 Another form of ema wish is for "tie-cutting";[3]^: 56 whereas a man and woman standing beside a palm tree is interpreted as a wish for a long relationship, another plaque depicts nettles between the couple, wishing for divorce.[2]^: 158 Common symbolism also includes nettles placed beside an object one wishes to sever ties with. During wartime, ema depicting the same man, one in military uniform and one in civilian clothing, suggested a desire for a soldier to sever from his civilian life.[3]^: 56 For some, the same image may have been used to express a wish to avoid military service altogether.[3]^: 57

The use of text has gradually replaced the overt use of symbolism in contemporary ema.[1]^: 33 The rise of literacy has encouraged guests to write their own messages, which has dramatically decreased the use of distinct ema as a way to transmit a specific wish.[1]^: 34

As a ritual, the ema is a means to communicate wishes to both priests and the kami. The public nature of the ema, which are displayed at shrines before their ritual burning, also serves a social function for communicating to the community that an individual has made the wish. Burning the wishes helps to "symbolically liberate" the spirit of the wish into the world. In some cases, however, wishes are taken from the shrine to be hung at home, though still ritually burned in special ceremonies.[3]^: 53
