10 Methods of Concealment & Spying

1 – ONSEI NIN: This is the art of concealing yourself by the method of noise, such as music or the noise of animals such as horses.

2 – JUN NIN: This is following people with natural movements without destroying anything.

3 – MUSEIHO NIN: During troubled times it is necessary to be ready to sacrifice everything, even in a dead end situation. The enemy may be blinded by pity or overwhelmed by other feelings, which will grant you the possibility of escape.

4 – NYOGEN NIN: No matter how slim the situation. you should recognize the principal at once and profit from it in order to gain an advantage.

5 – NYOEI NIN: Under no pretext allow yourself to be separated from people; stick firmly to you goal.

6 – NYOEN NIN: During the times when people are not cautious or negligent enter their houses and their hearts.

7 – NYOMU NIN: Be capable of evaluating individuals.

8 – NYOKO NIN: Examine the enemy’s territory and adapt to it.

9 – NYOKA NIN: Study the enemy’s deepest depths and learn the most intimate recesses of his heart. Under these circumstances, in order to not behave suspiciously, you must act naturally or in disguise.

10 – NYOKY NIN: If and adversary has discoverd that he is being spied upon, all effort to defeat him will then be in vain. IT IS VERY IMPORTANT TO NEVER leave a trace when you are spying.

These are the 10 basic or kihon methods of spying that are covered in the Shoninki. Again this is considered basic knowledge of the historical shinobi and should be mastered and taught by ALL schools of ninjutsu.
