In the history of Japan, ninja (also known as shinobi) operated as spies, assassins, or thieves; they formed their own caste outside the usual feudal social categories such as lords, samurai, and serfs. Ninja often appear as stock characters in Japanese and global popular culture.
Ninjas first entered popular culture in the Edo period. In modern Japan, ninja are a national myth that stems from folk tales and continues through modern day popular culture. [1] Though many Japanese warriors performed amazing feats, there is no evidence that any of them were supernatural. Some of the folk tales are based on historical figures, such as a daimyō (lord) challenging a ninja to prove his worth by stealing his pillow or weapon while he slept. [2] : 14

Superhuman or supernatural powers were sometimes associated with the ninja. Such powers include flight, invisibility, shapeshifting, the ability to "split" into multiple bodies, the summoning of animals, and control over the five classical elements.[ citation needed ] These notions stemmed from popular imagination regarding the ninja's mysterious status, as well as romantic ideas found in later Japanese art during the Edo period. Magical powers were sometimes rooted in the ninja's own efforts to disseminate fanciful information.[ citation needed ] For example, Nakagawa Shoshujin, the 17th-century founder of Nakagawa-ryū, or martial art style, claimed in his own writings (Okufuji Monogatari) that he had the ability to transform into birds and animals. [2] : 13
Perceived control over the elements may be grounded in real tactics, which were categorized by association with forces of nature. For example, the practice of starting fires in order to cover a ninja's trail falls under katon-no-jutsu ("fire techniques"). [3]
The ninja's adaption of kites in espionage and warfare is another subject of legends. Accounts exist of ninja being lifted into the air by kites, where they flew over hostile terrain and descended into or dropped bombs on enemy territory. [4] Kites were indeed used in Japanese warfare, but mostly for the purpose of sending messages and relaying signals. [5] : 257 Turnbull suggests that kites lifting a man into midair might have been technically feasible, but states that the use of kites to form a human "hang glider" falls squarely in the realm of fantasy. [2] : 22–23
Kuji-kiri is an esoteric religious practice which, when performed with an array of specified hand "seals" ( kuji-in ), or gestures, was meant to allow the ninja to interact with the spirit world and allow them to perform superhuman feats.[ citation needed ]
The kuji ("nine characters") is a concept originating from Taoism, where it was a string of nine words used in charms and incantations. [6] : 2–3 In China, this tradition mixed with Buddhist beliefs, assigning each of the nine words to a Buddhist deity. The kuji may have arrived in Japan via Buddhism, where it flourished within Shugendō. [6] : 13 Here too, each word in the kuji was associated with Buddhist deities, animals from Taoist mythology, and later, Shinto kami. [6] : 24–27 The mudrā , a series of hand symbols representing different Buddhas, was applied to the kuji by Buddhists, possibly through the esoteric Mikkyō teachings. [6] : 24–25 The yamabushi ascetics of Shugendō adopted this practice, using the hand gestures in spiritual, healing, and exorcism rituals. [7]
Later, the use of kuji passed onto certain bujutsu (martial arts) and ninjutsu schools, where it was said to have many purposes. [6] : 31–33 The application of kuji to produce a desired effect was called "cutting" (kiri) the kuji. Intended effects range from physical and mental concentration, to more incredible claims about rendering an opponent immobile, or even the casting of magical spells. [6] : 31 These legends were captured in popular culture, which interpreted the kuji-kiri as a precursor to magical acts.[ citation needed ]
In modern popular culture, there were three major "ninja booms" in the 20th century, the first two booms largely limited to Japanese popular culture before becoming a global phenomenon with the third boom. The first boom was during the 1910s to 1920s, when the Sarutobi Sasuke series of children's novels became popular in Japan; the series depicted its shinobi protagonist as essentially a prototypical superhero, capable of a number of superhuman feats. [8] [ unreliable source? ] [9] The second "ninja boom" was in the 1960s, with the rise of Japanese ninja films, manga and television shows that became popular in Japan. [8] By the mid-1960s, there were numerous popular ninja-themed media produced in Japan and it became popular for Japanese children to wear ninja costumes. [10] During this second boom, some of the Japanese ninja-themed media were exported to several international markets such as Australia and Italy, but did not reach North America. [8] This was also when ninjas made their first appearance in a Hollywood production, the James Bond film You Only Live Twice (1967), though the film depicted them more as commandos rather than traditional ninjas. [11] The third "ninja boom" was in the 1980s. [8] It was during this period in the early-to-mid-1980s that ninjas became a global phenomenon. [8] [10]
In North America, the success of Hong Kong martial arts films such as Bruce Lee's Enter the Dragon (1973) led to mainstream interest in martial arts films from Asian cinema, with American entertainment companies looking for the next "chopsocky" craze from Asia to repeat the success of 1970s kung fu films. [10] Ninjutsu drew some American interest in the late 1970s, but was not very popular at the time. [12] In 1977, the Japanese arcade game company Kasco released a light gun shooter electro-mechanical game called Ninja Gun, [13] [14] [ unreliable source? ] which helped introduce a number of American children to ninjas by the early 1980s. [15] Eric Van Lustbader's novel The Ninja was published in 1980 and went on to become a New York Times Best Seller. [15]
Around 1980, several American companies took notice of the "ninja craze" in Japan and were planning to capitalize on it with their own ninja-themed productions targeting the North American market. In March 1981, Variety magazine announced that fourteen American entertainment companies were planning to produce ninja films, including Zanuck/Brown Company's The Ninja, Stirling Silliphant's The Masters, and The Equals starring Scott Glenn and Toshirō Mifune, among others. However, several of these ninja-themed productions either did not release or failed to gain much success upon release. [10] The North American breakthrough for ninja films came with Enter the Ninja , directed by Menahem Golan and released by Cannon Films in 1981, the success of which sparked the "ninja craze" in American popular culture and led to a wave of American-produced ninja films and television shows in the 1980s. Enter the Ninja also launched the career of Japanese martial arts star Sho Kosugi, who starred in its successful sequel Revenge of the Ninja in 1983 and portrayed ninja characters in other successful 1980s American productions such as The Master television series in 1984. [16] A wave of ninja-themed films and television shows during the early-to-mid-1980s, especially those starring Sho Kosugi, led to "ninjamania" becoming a pop culture phenomenon across North America. [12]
Many forms of ninja-themed merchandise were sold across North America during the early-to-mid-1980s, with American children replacing cowboy costumes for ninja costumes. [12] It became a trend for items to be branded with the word "ninja" to generate more sales. For example, Parfums de Coeur introduced a perfume called Ninja which generated US$20,000,000(equivalent to $67,000,000 in 2023) in sales over several years up until 1985, and the Kawasaki Ninja series of motorbikes were introduced in 1984. [15]
Ninja video games emerged and became popular during the 1980s. [17] Early ninja-themed video games included SNK's arcade shooting game Sasuke vs. Commander (1980), [18] Taito's arcade games Ninja Hayate (1984) [19] and Legend of Kage (1985), [20] Sega's Ninja Princess (1985) starring a female ninja, [21] and Konami's Ganbare Goemon series (1986 debut) based on the folk hero Ishikawa Goemon. [22] Early ninja-themed home computer games included Saboteur (1985) and Ninja (1986), the latter featuring artwork resembling Sho Kosugi. Perhaps the most influential ninja video game was Sega's arcade hit Shinobi (1987), which spawned the Shinobi series, the longest-running ninja video game franchise. Series protagonist Joe Musashi was one of Sega's flagship characters in the late 1980s, along with Alex Kidd (before Sonic the Hedgehog). [17] Shinobi was followed by a wave of ninja video games in the late 1980s, [17] with some of the most popular including Taito's The Ninja Warriors series, [23] System 3 Software's Last Ninja series, Data East's arcade hit Bad Dudes Vs. DragonNinja (1988), Tecmo's Ninja Gaiden series starring Ryu Hayabusa, [17] and Capcom's Strider series. [24]
Some of the largest ninja-themed international media franchises include Teenage Mutant Ninja Turtles (comic book debuted in 1984, animated series in 1987) and Naruto (manga debuted in 1999, anime series in 2002). [25] [26]
The 1998 East Java ninja scare was an outbreak of mass hysteria in East Java, Indonesia, in which the local population believed they were being targeted by sorcerers known as ninja, who were blamed for mysterious killings of religious leaders by assassins dressed in black. As many as 150-300 “sorcerers” were killed between February and October, with the most deaths occurring between August and September. [27]

His family name, meaning "monkey jump", is written with two kanji; saru (猿) is the character for "monkey", and tobi (飛) is the character for "jump". He was known for his monkey-like agility and quickness, especially in trees. Many depictions portray him as having been orphaned and raised by a band of monkeys, therefore giving rise to the monkey-like abilities. He has been described as a superhero ninja, and caused a boom of ninjas in popular culture during the 1910s-1920s in Japan.
