Ninja Still Alive: Devoting One’s Life to Ninjutsu Training and Study

What is your image of ninja? Their image that comes to mind for most people is of someone clad in black clothes, sword strapped to their back, hurling shuriken throwing stars, and running across the surface of water or disappearing in a puff of smoke. However, that set image is all just the creation of movies, TV dramas, and the like. The real “persons of shinobi” active during the 16th century Sengoku period were actually very different. Read for yourself and find out more…

Jinichi Kawakami, the present day ninja who inherited the techniques and knowledge of shinobi passed down from the 16th century Sengoku period (the Warring States period) Jinichi Kawakami, associate professor at Mie University Community Research Cooperation Center and 21st generation teacher of Koka-ryu Ban-to ninjutsu

Building up His Training Since Boyhood

Jinichi Kawakami was born and raised in the Uryu district of the town of Wakasa, Fukui prefecture. He was just six years old in 1955 when he met an old man by the name of Masazo Ishida. Ishida frequently came to Uryu village from his residence in Kyoto, staying for long periods at the local kichinyado – the cheapest class of traditional Japanese hostelries – and making a living as a peddler selling medicines and other goods. Ishida was also a master of Koka-ryu ninjutsu3. Before they knew it, the two had entered into a teacher-student relationship and Kawakami began learning ninjutsu.

“He taught me how to clamber up houses and cliffs all over the village, skillfully jump down from high places, and how to infiltrate a house via the roof! I also studied how to submerge myself underwater, and the varieties and usages of poisonous and medicinal herbs found while scurrying around the mountains,” Kawakami recalls.              

Of course, Kawakami was also instructed in disciplines such as the methods of various forms of martial art and strategy. At that time, Masazo Ishida was thought to be around 70 years old, but it seems he was able to masterly perform all manner of techniques in order to show them to his disciple. In addition, all of Ishida’s knowledge was stored in his memory and passed down to Kawakami orally.

The dojo (training hall) in Uryu

Although Ishida’s household was in Kyoto, his ancestors were of samurai (warrior) lineage in Koka, Shiga Prefecture. When the Koka Imperial Corps were set up during the bakumatsu – the closing years of the Tokugawa shogunate and Edo Period (1853-1867) – the ninjutsu that had been passed down to each household, including the Ban household which was of ninja lineage, was supposedly gathered together and the techniques and knowledge re-learned by all. This had been passed on from generation to generation until it reached Masazo Ishida. The name of this faction of ninjutsu was “Koka Shinobi no Den.”

At the age of 18, Kawakami became an instructor and was permitted to call himself the 21st generation teacher of Koka-ryu Ban-to ninjutsu. He continued learning ninjutsu from Ishida until he was around 19.               Why did the elderly Ishida, whose home was in Kyoto, journey out to Uryu (about 50km away from each other) and stay there frequently for long periods? Why did he pass his ninjutsu knowledge on to Kawakami? The young Kawakami rarely played with other children his own age. Ishida and Kawakami likely got on well and overcame their age difference because they both loved solitude. By instructing the young Kawakami, who took on his training earnestly every day, perhaps Ishida felt he was preserving ninjutsu, which was in the process of decline, for the next generation. We cannot ascertain the feelings of the deceased Ishida. However, with Kawakami taking over his mantle, the fact that many of the techniques and knowledge of shinobi have been passed through to the 21st century is in no doubt.

Aim of Establishing “Ninjutsu Study”

Even after graduating from school, Kawakami continued his training while working for a company. “After coming home from work at nine or ten o’clock, I’d hurriedly have something to eat and manage to train or study for a few hours before going to sleep late at night. Then I’d wake up early in the morning and go to work again. That was my daily pattern,” Kawakami recalls of that time. Naturally, he was only getting a few hours of sleep, but Kawakami says that he never let up on his practice no matter how tired he got. While he was doing this, his mastery of ninjutsu became known to the outside world little by little and people also started visiting him with the hope of becoming his disciple.

However, Kawakami does not teach just anybody. In fact, he turns away all requests at first. Only those who still have the passion and will to learn despite Kawakami’s rebuffs are accepted as his disciples. This is because ninjutsu training is extremely severe and Kawakami knows that those who begin training just out of curiosity are never in it for the long run.

Thirty years passed. Kawakami, who was by then in his 50s, retired from the company he had worked for. He firmly resolved to devote the latter stages of his life to ninjutsu.

At the time of his retirement, Kawakami was asked to become the honorary curator of the Iga-ryu Ninja Museum in Iga City, Mie Prefecture. As some readers may be aware, Iga City has made efforts to publicize and spread word of its ninja culture as one of its policies toward regional revitalization. As a part of this activity, Iga City appointed Kawakami, the leading figure in ninjutsu.

 Some people may find it strange that Kawakami, an exponent of Koka-ryu ninjutsu, should be involved with Iga-ryu. However, Koka and Iga were never originally opposed to each other. In fact, there have been many alliances between them and geographically they are situated next to each other. However, during the course of his bid to unify Japan, Nobunaga Oda – a powerful feudal lord – attacked Iga in a bid to suppress the renegade province. At the time of this event, which is known as the Tensho Iga rebellion (1579-1581), the majority of Koka warriors and a section of Iga warriors joined Nobunaga’s side, so the image remains of the two sides opposing each other. In addition, Iga and Koka are often depicted as mutual enemies in movies, TV dramas, and the manga world, which helps spread this general image of them. Actually, as schools of ninjutsu, there are no sizeable differences between the two.

As an extension of his tie-up with Iga City, Kawakami was offered the chance to give lectures hosted by Mie University, a national university, which was setting up an industry-government-academia cooperative. As the exchanges between Kawakami and persons connected to the university deepened, the university brought up the subject of whether the two sides should press ahead with research into “ninjutsu studies” – i.e. ninjutsu as a genuine academic discipline. It seems Kawakami was surprised by this suggestion at first, but came to think that a good chance had come his way. Until then, the existence of ninja, their history, and ninjutsu itself had hardly been spoken of in an academic context. On the contrary, some scholars even denied the existence of ninja.

Perhaps because ninja undertook secretive work, hardly any records of them remain. There are extremely few written historical records with a high degree of reliability that are related to ninja. But even looking at the few historical records currently in existence, there is no doubt that there were at the least some persons whose activities were “ninja-like.” However, as substantiating this is difficult, the academic world has avoided the subject until now.

Kawakami thought that he should take this opportunity to continue research into ninja and firmly prove their existence to the academic world. At the same time, he established the study of ninjutsu itself with the additional aim of ensuring that it would not fail to be passed on to later generations.              

These are the events that led to Kawakami being welcomed as associate professor at Mie University Community Research Cooperation Center and embarking on a new stage of his life.

Shinobi: Part of the “Art of War”

Mention “ninja” and the image that comes to mind for most people is of someone clad in black clothes, sword strapped to their back, hurling shuriken throwing stars, and running across the surface of water or disappearing in a puff of smoke. However, that set image is all just the creation of movies, TV dramas, and the like. The real “persons of shinobi” active during the 16th century Sengoku period were actually very different. The ridiculous way in which some of these ninja came to be depicted is one reason why scholars tend to deny their existence, and this is the point that most concerns Kawakami.

Looking up, one can see rows of lances and spears

Firstly, misunderstandings surrounding the fundamentals of ninjutsu need to be resolved. Ninjutsu was not originally a strange magic-like battle tactic. It would be better understood as a military strategy activity or part of the “art of war.” In short, ninjutsu refers to a range of techniques and knowledge that were actually used in the conflicts that raged throughout medieval Japan. Examples include intelligence gathering and espionage methods, how to sneak into enemy territory, and especially the unique combat methods known as yashu and kishu (“night attack” and “surprise attack”). Persons skilled in these techniques were known as “shinobi” or “persons of shinobi.” In this sense, ninjutsu is more about actual combat than other military strategies that include theories worked out from behind a desk.

For example, a general should always try to probe for enemy information before the battle. Ideally, there would be no battle; the problem would be solved without any blood being spilt. To that end, the enemy may be diplomatically placated or bribes may be paid. Controlling an opponent’s mind using methods like these also falls within the remit of the ninja. If war should actually break out, while keeping damage to their own forces to a minimum, generals would send ninja into enemy territory to spring night attacks and surprise attacks. On days when the wind was strong, ninja would sneak into the enemy camp and start fires. Alternatively, ninja would use poisons to annihilate the enemy. Successfully carrying out such dangerous strategies required sophisticated shinobi techniques, and wherever and whenever war erupted, there was always some form of professional “person of shinobi” active behind the scenes.

Although this may shatter your image of ninja, the shuriken throwing stars thought of as the typical ninja weapon were actually rarely used at all. Shuriken were originally just one of the many tools and implements used in martial arts. The image that ninja always use shuriken was again no more than a creation of movies and TV dramas.              

So why did the Koka and Iga clans become famous among ninja? Kawakami thinks the reasons for this may be as follows: “Both Koka and Iga are positioned between Owari (Nagoya in the present day) and Kyoto/Osaka, and those geographical conditions were likely significant. This area was the focal point of the Sengoku period where the daimyo (powerful feudal lords), vied for supremacy. Against this backdrop, the Koka and Iga clans with their superior techniques and knowledge were given prestigious positions as mercenaries.”

Shuriken and uchikagi (grappling hooks) used for training

When the Edo period (1603 to 1868) began and Japan entered an age of peace and tranquility, the battles in which ninja had been active dissipated. However, descendants of ninja and those drawn from the ninja tradition established numerous schools to ensure that ninjutsu was passed on. The text Bansenshukai (“Sea of Myriad Rivers Merging”), which records details of ninjutsu, was also written during this period. The manuscript still exists today. That ninjutsu was of high value was surely the reason why efforts were made to preserve it for future generations. What Kawakami learned from the venerable Ishida was this very same ninjutsu, passed down in an unbroken chain.

The Keys to a Living Ninjutsu

Kawakami will probably teach at universities in the future, but what will his lectures be like? As mentioned previously, the focus of ninjutsu is combat and espionage methods. Depending on the content, these methods may also include a considerable number of elements that are socially unethical today. But whatever the activity, developing something to a high level reveals a truth about humanity, and in order to win wars, “knowledge of humanity” is also essential.

According to Kawakami, people desire five things: food, sex, possessions, refinement (of pursuits and ideas), and honor. People also experience five main emotions: joy, anger, sorrow, enjoyment, and fear. Ninjutsu attempts to cleverly use these desires and emotions to entrap or placate the enemy.

The true nature of humanity itself is constituted by the five desires and five emotions. By putting these desires and emotions to use and channeling them in a positive direction, people living in the present day could improve the way they live their lives. On the other hand, the three pillars of the art of war – seizing opportune moments, utilizing the terrain, and harmony among people – were used by ninja in an attempt to win victory. For example, the ninja would arrive at an inopportune time for the enemy opponent, lead the opponent to places with unfavorable conditions, and disrupt the personal harmony among foes. Those elements of ninjutsu could also be put to use in business environments, but there may be some ethical issues with these methods in the present day.

However, Kawakami does not seek to apply the three art of war techniques to attacking rival groups. If the techniques were instead put to use toward the opposite end – to utilize one’s own opportunities and surroundings and to improve teamwork among colleagues – people would surely be able to achieve greater success at work, too. Furthermore, the physical exercise involved in activities such as martial arts promotes health, while the techniques used to survive in the countryside could be applied as a means of protecting oneself in the event of a disaster.
Ninjutsu techniques and knowledge were originally for combat, but as they are so sophisticated, they have a universality that transcends generations. Kawakami is also engaged in the idea of producing watertight theories so that anyone can appreciate the usefulness of ninjutsu in the present day. “Over the next 10 years or so I’d like to build a springboard for discussion for those studying ninjutsu in the future, both as an academic discipline and to pass the tradition on,” he says.

The ninja adopts the following three mental attitudes: do not be afraid; do not underestimate or take something for granted; and do not think too much. Armed with these three mental attitudes, Kawakami, the ninja of the present day, is seeking the path holding even higher ideals, taking on challenges in unknown territories.
