Ninja
What do you imagine about Ninja? Is Ninja a superman? Assassin? Spy? Master of martial arts and swordsman? Shuriken(throwing starry knife)? Shinobi Syouzoku(Black Ninja's suit)? Smoke screen bomb?
I think that you already know about Ninja from Anime, Manga, Movie, Novel and etc... There is a lot of Ninja information everywhere.
And all people believe Ninja has super power. Because Ninja play an super action as superman in the movie, even the Mutant Turtle.
BUT is that a truth? Is Ninja a superman? Assassin? Spy? Do they always wear the black suit?
To begin with, who are they?
Truth
Ninja information is overflowing in all the world. But correct information is very few. And most of all people don't know Ninja's true character.
I want to talk about Ninja's true character, what is a truth and what is a fiction. But if I talk my all knowledge about Ninja, the text will be over the limits of message length. But the truth is that I can not write so long English sentence.
I talk about Ninja by Question and Answer. I set questions and explain answers simply. Please enjoy Q&A.
If you have an another question, please ask me with a light heart.
Answer
Q1.Is the Ninja a real existence?
A1.YES
Of course Ninja is a real existence. But Ninja's true character is different from we know now. I talk about Ninja's true character from now.
Q2.Is "Ninja" active in all over the history?
A2.NO
The Ninja was born in the sixteen century. And they were active in all over Japan. But their influence fell in the first half of the seventeen century. They were active only in the sixteen century. Why dose their influence fell in the seventeen century? I reply this question in the Q20.
Q3.Is the origin of Ninja a Samurai?
A3.NO
The origin of Ninja is a Akuto. Akutou is an anti Establishment group. The constituent member of Akuto is a wanderer, sharecropper, robber, political offender, Gypsy, industrial workers, Samurai and etc. All sorts of people joined an Akuto. And they rebelled against the Government and organization of power. Akuto was born in the first half of the fourteenth century. This age is the Civil War age.
In ancient times, Akuto means an armed anti Establishment groups. But now, Akuto means a knave, rascal, villain and scoundrel.
Q4.Does "Ninja" means "Assassin" in Japanese?
A4.NO
Ninja is made from two characters(Kanji), "Nin" and "Ja". And those characters has own meaning. "Ja" means a person. What means the "Nin"? This character has three meanings. The first is "patient", the second is "hide one's feelings" and the third is "act secretly".
I think that you agree on the third meaning "Ninja means a person who act secretly". But what is the first and second meaning? Is Ninja a patient person? Why dose Ninja hide his feeling?
There is a good reason of the first and second. An instance, poker face. If you want to win a game, you must not show your intentions. And you will make a poker face. But if you are a quick temper, you can not keep poker face. It need patient mind to keep poker face. And it is the same as Ninja. Ninja must hide his feelings to win against enemy and it is need to patient mind.
What is Assassin in Japanese? Assassin is Ansatsusya in Japanese. Ansatsusya is made from three characters(Kanji), "An", "Satsu" and "Sya". "An" means "dark", "Satsu" means "kill", "Sya" means "person". "Sya" is the same Kanji with "Ja" of Ninja. Ansatsusya is a "killer in the dark" in literal.
Q5.Is Ninja a Spy?
A5.YES
Ninja is a Spy and Guerrilla, but not Assassin. They scout an enemy area and army. Their main mission is a information gathering, spreading a false rumor, subversive activities and guerrilla tactics. Their workshop is in the dark. Of course assassination is one of the dark business. But assassination is not their main business. If anything, there is never a famous victim of assassination by Ninja.
Q6.Was there a Ninja's country(province).
A6.YES
Usually ruler is a Samurai(The Shogun and a lot of Daimyo) in Japan. But Iga was a Ninja's country(province).
The origin of Ninja is a Akuto. And Akuto is an anti Establishment group. The farmer(Akuto) of Iga had been independent of the Establishment. And they made an independent country. It was a republic and was managed by the representatives of villages. But Iga was destroyed by the daimyo Nobunaga in A.D. 1581. And after, Iga was under the control of the Establishment.
Q7.Dose Ninja pledged their loyalty to Daimyo?(Daimyo is a feudal lord in Japan)
A7.NO
The Ninja was born in the sixteen century. And this age was the Age of Daimyo Wars. In this age, all Daimyo(feudal lords) contended with each other for the Shogun(throne). And a lot of Ninja group cooperated with Daimyo. But Ninja has a strong spirit of independence. They didn't under the control of Daimyo. And they never pledged their loyalty to Daimyo. Ninja worked for Daimyo, but it is a contract but not superintendence. Ninja has contracted a Daimyo for the dark business. If employer lose a war, Ninja desert their employer.
Q8.Was there a Ninja school to learn the Ninjyutu?("Ninjyutu" means "Art of Ninja")
A8.NO
Ninjyutu is a top secret. There was not a Ninja school. How do learn the Ninjyutu? Ninjyutu was transmitted directly from Ninjutsu master to pupil.
Q9.Did Ninja train in Ninjyutu all day?
A9.NO
Ninja is a specialist in the dark business. And they are well trained. But their business is not only in the dark. Because they are a farmer at ordinary times. They plowed a rice field in the morning, and they trained Ninjyutu in the afternoon.
Q10.Is Ninja a superman?
A10.NO
Imagine, if you are a Ninja in the Middle Ages. You don't have a NIKE shoes, and road is a gravel but not asphalt. Can you run faster than Maurice Green? It's an impossibility. Can you jump over a high wall easily but not clamb frantically up? It's an impossibility too. The Ninja as superman is a fiction, it's only in the story. If the Ninja can those super action, the world records of Olympic Games are broken by the descendant of Ninja.
Q11.Dose Ninja always wear a Shinobi Syouzoku(black suit)?
A11.NO
Ninja is a farmer at ordinary times. They wear a farm clothes at home. And they disguise themselves as a merchant, priest, monk and etc in the dark business. Why dose Ninja disguise themselves? Because they are a Spy. If they wear the Shinobi Syouzoku, it come to light that they are the Ninja(spy). There is not a man who say "I am a Spy" by myself. Ninja didn't wear the Shinobi Shouzoku always.
But Ninja wear the Shinobi Shouzoku in guerrilla warfare. And we imagine that the Shinobi Shouzoku is black color. But Shinobi Shouzoku has various colors, gray, yellowish red, dark blue, camouflage and etc. And Ninja choose yellowish red rather than black.
Q12.Dose Ninja carring Katana on his back(shoulder)?
A12.NO
Our Ninja's image is a Shinobi Shouzoku whit Katana on his back. But it is a fiction. Usually Ninja wear a sword at his side as Samurai. If Ninja carring Katana on his back, the Katana is hooked everywhere. And drawing sword at his side is more quick than on his back.
Q13.Does Ninjyutu means martial arts?
A13.NO
We imagine Ninja's skill as martial arts and super action. But it is not correct. Of course martial arts is one of Ninja's skill. But the most important skill is a spy skill. They learned how to get the information mainly.
Q14.Is Ninja good at disguise?
A14.YES
Ninja learned how to get the information. Disguise is one way of that. If you want to get enemy's information, how do you to get the one? Steal into enemy's house? It is not good way. In Ninja's way, Ninja disguise himself as a merchant and he visit an enemy's castle. Enemy don't know his true character and enemy rely on him as merchant. And Ninja can get enemy's information easily, without the risk of his life. Of course a thin veneer of education is useless, Ninja study "merchant" very hard to disguise, business, gestures, language, commodity and etc. And Ninja start a business actually.
Q15.Does Ninja use a extraordinary arms(Iron claw, Throwing starry knife, Sickle with chain and etc)?
A15.YES
Ninja use a various extraordinary arms. Ninja don't stick to a tradition and common sense. And they invent a various extraordinary arms. Ninja is a realist and pragmatist.
Q16.Is Ninja stronger than Samurai?
A16.NO
Samurai is a specialist in war but Ninja is a specialist in spy. Spy can not win against professional soldier. Of course Ninja is a specialist in guerrilla tactics. Ninja can win by a surprise attack, but can not win by a frontal attack. If Ninja is stronger than Samurai, Ninja conquered Japan. But Japan was conquered by Samurai but not Ninja. Ninja train military arts, but Samurai train military arts more hard. If Ninja is found out by Samurai, Ninja run away but not fight.
Q17.Dose Ninja has a higher status(social standing) than Samurai?
A17.NO
Ninja is a man in the dark and was misunderstood as burglar. Ninja has a great skill but Ninja's status is very low. Ninja was a synonym for a robber in the Middle Ages.
Q18.Can Ninja use Youjyutu(Ninja's magic)?
A18.NO
We have an image that Ninja can use Youjyutu(magic). An instance, Ninjya disappear with a smoke screen when he is cut. Of course it is a fiction. But it is a truth that ninja learn various magic, Buddhist magic, Shintoist magic and Taoist magic. We imagine that magic is not scientism. But in this age, magic is a synonym for science. They learned various magic seriously. And those magic is useful for disguise too. Because if Ninja disguise himself as a Buddhist priest, he must can use Buddhist magic. They made good use of magic, but it is a cheating. Ninja can not use real magic.
Q19.Is woman's Kurosyouzoku(Ninja's Bluck Suit) a miniskirt because easy to move?
A19.NO
Do you know that woman's lingerie was highly developed in the modern period? There was not panties and brassiere in the medieval period. And miniskirt is the latest fashion too. Until quite recently, woman covered her legs with long skirt. It is the same as Japan.
And woman Ninja don't wear the Kurosyouzoku. To put it more precisely, there was not woman Ninja. Usually Ninja is man only. Woman Ninja don't exist. But there was Kunoichi in Ninjyutu. What is Kunoichi? It means woman in jargon of the Ninja. KUNOICHI is a woman Spy. She tried to get information out of him(enemy) by turning on her charm. But kunoichi is not Ninja because she don't know Ninjyutu. She is a prostitute and is in the employ of Ninja. She is a agent of Ninja but not Ninja.
But enemy don't know her true character, prostitute and agent of Ninja. And enemy believed that she was a woman Ninja.
Q20.Dose "Ninjyutu" has been handed down by the secret scroll from generation to generation?
A20.NO
Ninja learn Ninjyutu directly from master. There was not a textbook(the secret scroll), oral instruction only. Ninjyutu is a top secret. Ninja was afraid of outflow of Ninjyutu. And Ninja didn't make a textbook. But this tradition is broken in the seventeenth century. The seventeenth century is a peaceful age. The war age is already concluded. And Ninja is a unnecessary existence in peaceful age. Ninja declined in this age. And Ninja is in a critical situation of downfall. Ninja made a textbook to leave Ninjyutu. But it was an simple instruction manual, there was not record of top secret. And Ninja went to ruin in the end. The most strong enemy of Ninja was the peace.
