Yōkai

Many countries around the world have their own legends, folklore, and folk beliefs. In Japan, numerous legends and stories have been passed down from generation to generation, such as the tale of 桃太郎 (momotarō—the Peach Boy). Among the many traditions and stories that have been handed down over the centuries are those concerning 妖怪 (yōkai). Although it's not entirely clear how yōkai first emerged, they have long been an important part of Japanese culture and folklore.

Yōkai have a long history. They're believed to have first appeared in the 日本書紀 (nihon-shoki), one of Japan’s oldest historical chronicles, during the Nara Period (710–794). Although they’re often described as “Japanese monsters”, yōkai are much more complex than that. Some take human form, while others appear as animals, and they exist in a wide variety of shapes and forms. As such, the term “monster” doesn't fully capture what yōkai are. Also known as 妖 (ayakashi) and 物の怪 (mono-no-ke)—terms that can refer to ghosts, specters, or other supernatural beings—yōkai are thought to have originated from mysterious phenomena and events that people couldn't explain. In traditional stories and folklore, they’re often described as possessing strange and supernatural powers.

Each region of Japan has its own unique culture and customs. What can be found in one part of the country may not be found in another. However, legends and traditions concerning yōkai can be found throughout Japan rather than being limited to a single region. Yōkai are not always visible. While some yōkai—such as the 化け狸 (bake-danuki)—are based on real animals (in this case, 狸—tanuki), many have never actually been seen. In Japan, it has long been believed that unseen beings and forces exist beyond the ordinary world. Because of this, many people believed that when a strange or mysterious phenomenon occurred that couldn't be scientifically explained, it was the work of a yōkai. In modern-day Japan, people hold a variety of opinions about yōkai and whether they truly exist. Nevertheless, yōkai have played an important role in Japanese culture and have influenced the values and beliefs of many people throughout the country's history.

For those with an interest in traditional Japanese culture, even if one doesn’t know much about yōkai, there’s a chance that one may have encountered many of them. It was during the Edo period (1603–1868) that yōkai became especially popular. They appeared in 浮世絵 (ukiyo-e—colored woodblock prints) and were featured in numerous books. They also became a common subject in various forms of art and cultural works. As a result, yōkai became more than just figures from legends and stories; they grew into a deeply rooted part of Japanese life and culture. Their widespread presence throughout history demonstrates the important role that yōkai have played in Japanese culture.

For many people, yōkai are seen as scary. However, that image has changed over time. In the modern era, yōkai have become beloved through comic books and cartoons, transforming into cute and endearing characters. One of the most influential works is ゲゲゲの鬼太郎 (ge-ge-ge-no-kitarō), created by the renowned Shigeru Mizuki. Shigeru Mizuki had a unique perspective on the world, which inspired him to depict countless yōkai in his works, captivating readers and viewers alike. In GeGeGe no Kitarō, the main character is 鬼太郎 (kitarō). Kitarō battles evil yōkai and investigates various supernatural incidents caused by mischievous yōkai. Through these stories, Shigeru Mizuki drew yōkai in a new and unique way. In doing so, he made them—and yōkai culture as a whole—more appealing to younger audiences. He also helped to keep yōkai alive and make them approachable for those in modern-day society.
