" Jujutsu in the Kaisen " - What that world means and who are they for real?
This topic has intrigued me for quite some time. During my university yearsâwhich are still ongoingâone of our Japanese text-reading classes featured a passage about the JĆmon period. The text mentioned jujutsu and the jujutsushi (shamans). Of course, I was already reading the manga by then, and it was around the time the second season came out, so I actively started researching. Below is what I found.
Letâs begin with a brief kanji overview: ćȘèĄ (Jujutsu)
Its core meanings include âspell,â âcurse,â âcharm,â or âprayer,â often used in connection with malevolent or supernatural things. It belongs to the kango family (meaning it came from China), which is used for traditional terms. Fun fact: During the Heian period, Chinese influence was huge, and this was when most Chinese kanji flowed into Japan, giving us yet another hidden Heian reference from the mangaka. This is also a compound kanji, meaning it was created by combining two smaller kanji in ancient Chinaâthe kanji for âmouthâ and âbrother,â which forms yet another wordplay. The âbrotherâ (which could refer to a monk or shaman) casts a spell or curse through his mouth. One long-standing issue with shounen anime is that characters always have to say their attack names, which can seem cheesy, but not in Jujutsu Kaisen. Gege solves this by introducing the legend of shamans, who could only cast spells through their spoken words, thus creating a logical basis for why attack names must be spoken aloud.
It is most commonly used to mean âart,â âtechnique,â âmethod,â or âskill,â especially in contexts requiring some level of expertise or technical knowledge. Itâs also a kanbun word and another compound kanji, though in a slightly different way than the previous oneâthis might deserve a separate article. Itâs used frequently, not just in the word jujutsu (which refers to the technique of magic), but also appears in Naruto, where the same kanji forms part of ninjutsu. Youâll also find it in more sophisticated words like bijutsu, which refers to the fine arts. But enough linguisticsâletâs move on to who the jujutsushi were.
The jujutsushi of the JĆmon period (ca. 14,000 BCE â 300 BCE) were not specific historical figures, but rather a term referring to the practitioners of jujutsu. However, jujutsu here should not be understood as a modern martial art, but in its original meaning, referring to the art of curses or magic.
The jujutsushi (ćȘèĄćž«) were individuals who practiced magic, rituals, curses, and spiritual activities. In the JĆmon period, these people were likely spiritual leaders, shamans, or healers who maintained a connection with the natural and spiritual worlds. During this era, people believed only in nature and the things around them, and these shamans were responsible for ensuring the mental well-being of the tribes. They were thought to possess the ability to foresee the future, return from the dead, and influence the weather. In other words, they were considered omnipotent. This is especially interesting because weâre dealing with a time far before the Heian periodâthe JĆmon can be considered Japan's prehistoric age. Isnât it fascinating that Heian-era Sukuna could only be defeated by magic much older than his own? In my humble opinion, this is a brilliant idea.
When discussing the Heian period, even 20 volumes would not suffice to fully explore the various magics and shamanism, but since weâre focusing on Jujutsu Kaisen, Iâll highlight two key spiritual traditions:
The first is incredibly interesting in its own right, as it not only inspired JJK but also countless other anime, manga, and games. Itâs none other than OnmyĆdĆ and the OnmyĆji. One of the most significant spiritual traditions of the Heian period, OnmyĆdĆ (é°éœé), developed from Chinese yin-yang philosophy and astrology. The onmyĆji (é°éœćž«) were sorcerers or spiritual advisors who served the aristocracy and the imperial court. Their duties included exorcising evil spirits, performing rituals to bring good fortune, observing celestial movements, and conducting curse-breaking ceremonies. The onmyĆji can be seen as the jujutsushi of the Heian period, as they too dealt with spiritual defense and magical techniques. Some of you may know that the Heian period was named after the capital city of the time, Heian (modern-day Kyoto), so itâs not far-fetched to assume that both spiritual traditions originated from there. And speaking of jujutsu techniques from the Tokyo school, those are more rooted in Buddhist foundations. Megumiâs shikigami also come to mind, which are not particularly Buddhist, but then I remembered that he comes from the Zenin clan, which is based in Kyotoâso weâre still on track.
The second tradition was more Buddhist and spiritual during the Heian period, known as Esoteric Buddhism (MikkyĆ). Another major spiritual and magical system in the Heian period was esoteric Buddhism, associated with the Shingon and Tendai Buddhist schools. Priests performed intricate rituals and magic aimed at relieving human suffering and banishing evil spirits. The ceremonies often involved reciting mantras, using mudras (hand gestures), and employing mandalas. This tradition utilized mudras, which can be understood as hand gestures. Many characters in the series use this symbolic system. I wonder if youâve noticed the sequence of mudras shown one after another in the second opening of the second season?
One last FanFact and that's it for today:
In Esoteric Buddhism, protective deities like FudĆ MyĆĆ (Acala) are common. These deities are strong, warrior-like protectors who can be invoked through rituals for protection. Similar defensive techniques also appear in Jujutsu Kaisen, such as the Domain Expansion (é ćć±é, RyĆiki Tenkai) techniques, which create a user-controlled territory. These resemble the ritualistic circles and protective symbols used in Esoteric Buddhist practices. In Jujutsu Kaisen, these techniques often involve spiritual or magical power to defeat opponents within the controlled area.
That's it for today! This topic might be worth a second part in the future, but we'll see. Do you have any questions? If there's any topic about Jujutsu Kaisen you're curious about, feel free to reach out to me!
