The Two Meanings of “Respect for Harmony”

The NINJA FOREST Interpretation of “Harmony is to be Valued.”   The phrase “Harmony is to be valued.” is written in Article 1 of the Seventeen-Article of the Constitution in the Chronicles of Japan. It has also become a proverb that expresses a spirituality that is essential to the Japanese. However, there are two main interpretations of this phrase. In this column, we will look at this phrase from both sides. The first interpretation emphasizes the importance of maintaining harmony in a situation, and that individual patience is necessary to achieve harmony. The other interpretation is that it is necessary to have a process which allows each of us to put forth our ideas and discuss them sufficiently in order to maintain harmony. I would […]

Strategy is the Best Way to Minimize Warfare

“A superior Ninja (Jyonin) is a man with no sound, no smell, no praise for his wisdom, no fame for his valor, whose deeds are like the creation of heaven and earth. (Bansenshukai)” A Ninja’s mission was primarily about gaining useful information to avoid unnecessary battles. Another duty was to increase the odds of survival, such as stealthily saving the lives of warlords and other influential or reducing the scale of warfare. Their work helped to prevent the loss of troops and provisions and minimized the chaos in the battlefield during times of prolonged warfare.   Sun Tzu said, “One hundred victories in one hundred battles is not the best of goodness.” (Meaning, even if you fight a hundred times and win a hundred times, […]

The Art of Interchanging Fiction and Reality

No hesitation, be confident. The fiction-reality conversion technique is a tactic that skillfully interchanges fiction and reality (bluffing and honesty) to gain an advantage in a confrontation or diplomatic situation. It’s a strategy that takes advantage of an individual’s psychology, such as making something appear to be there when it is not or acting confidently even when feeling unsure. There are two sides to every coin. No matter how perfect, excellent, or strong an opponent may appear to be, there is always a weakness hiding under the surface. With careful observation, you will be able to spot and exploit a rival’s emotional weak points to gain control of the situation. Ninjas used this technique of shifting fiction and reality, such as acting confident even if […]

Win without fighting

What you want to fight for and what you want to get out of it The best way to fight, as described in the Art of War by Sun Tzu, was to “win without fighting.” The one who wins may be good at the time, but he will surely suffer losses in repeated battles, such as losing his own soldiers, running out of food, and destroying the land. On the other hand, the loser will be frustrated and look for an opportunity to take revenge, and in any case, in the long run, battles involve sacrifices on both sides and a negative chain of events. To avoid this, it is necessary to have useful information to formulate efficient strategies, which is why Japan has created […]

Right mind~Why Ninja is different from bandits~

  Remember the right mind.   If Ninjutsu is misused, it is the same as banditry. Ninjutsu should be used for the greater cause, not for personal gain. (Quoted from the book of Ninjutsu, Bnasen shukai) Ninja had various techniques based on infiltration and psychology to sneak into houses and people’s minds by setting fires, confusing people by spreading rumors. It was precise because he was such a ninja that he reminded himself not to forget the “right mind.” And as a ninja, he also made a firm promise not to use his skills and abilities for personal gain .   When Ninja were active in the war period, their goals were to “survive” and “return with useful information.” This is because fighting by utilizing […]

Knowing yourself deeply

Knowing who you are In order to become a good ninja, it is important to always be aware of the words “You should know about yourself.”(*)   Even today, knowing your limits mentally, capacity and physically can help you perform at a high level and respond calmly to pinch points and problems. It is a very important risk management to understand your ability correctly on a daily basis and not to overlook the signs that you are “I can go a bit further” or “It’s getting dangerous.” If you stop and think about your next move flexibly or take a break when necessary, you will be able to keep moving for a long time and may be happy in this 100-year period of one’s life.

Equipment that helps you (six ninja tools and their modern versions)

 Six Ninja Tools and the Modern Six Ninja Tools The ninja’s six tools were the minimum necessary tools that the ninja carried with them on their missions. Even so, they were not the same every time, and they chose the necessary items according to the mission and situation. The fact that these are not weapons such as swords or shurikens, but tools for everyday use, shows that “ninjas are not fighters. It’s also important to be flexible enough to use what you have around you, such as rocks, sand, and branches, without relying on tools. Let’s look at them one by one. ■1■ Amigasa :Braided hats: to cover the face, shade from the sun, protect from the rain, protect the head (instead of a helmet), shield (armor) in […]

An Ideal Day in the Life of Kunoichi Kuze

If you can have a day like this, your mind and body will feel refreshed. I hope that the more you are always pressed for time, the more you can regain your “own pace” by setting aside some time and space for yourself, even if it is short, to reset and refresh your day. 05:00 Woke up.

To fight is to protect.

Ninja arts are for gaining time and escaping!? Japanese people tend to find beauty in the end, but the mission of the ninja was to  (1) stay alive, (2) bring back information, and (3) return home. For this purpose, escape was a higher priority than fighting and settling things in black and white. Ninjas flee in a cloud of smoke or using gunpowder to startle the opponents, and then they would take  that opportunity to run and hide. “I will neither run nor hide! “and contrary to the expression that is often used in period dramas, why do ninjas run away to such an extent? It was because they knew that there were battles that could be avoided thanks to the information they brought back, […]

The Deeper Meaning of Shuriken

Shuriken is a weapon and a talisman. The image of the ninja as using shurikens is influenced by Kabuki and period dramas. Of course, there were times when they used shuriken, but in fact, the modern view is that their main use was as amulets. A few hundred years ago, iron was expensive and required a lot of skill to process. The reality is that the ninja were not rich enough to disperse them, that they were not enough weapons to inflict fatal wounds on their opponents, and that they were too heavy and noisy to carry many of them around, so they kept one or two in their pockets for protection. I’ll add a note for people those who are shocked if I change […]



くノ一空世(くぜ)が主に担当。 海外3カ国で12年間生活した自分が「日本人としてできること」を模索する過程で知り合った忍術道場の師範から「忍者」についての話を初めて詳しく聞き、その奥深さと平和への思い、そして哲学性に衝撃を受ける。「日本人の不器用な生き方」を解きほぐすヒントはそこにあると感じ、その場で入門して修行を開始。 サバイバルの達人・忍者の「力で勝つ方法ではなく、しぶとく賢く面白く生き残るための方法」で、日本中そして世界中の大人を元気にするべく忍者として活動中! Mainly handled by Kunoichi Kuze. When I first heard about "ninja" in detail from the master of a ninjutsu dojo, whom I met in the process of searching for "what I can do as a Japanese" after living in three foreign countries for 12 years, I was shocked by its depth, thoughts on peace, and philosophical nature.I felt that there was a clue to unraveling the "clumsy way of life of the Japanese," so I entered the dojo and began his training on the spot. I am currently working as a ninja to energize adults in Japan and around the world with "not a method to win by force, but a method to survive in a persistent, smart, and interesting way"!
