Hiden

techniques are passed down from generation to generation orally in certain regions or clans.

The groups possessing these techniques are usually extremely secretive about them. They ensure that no one other than the members of the group learn them. Only a few hiden techniques require a special ability or lineage. These techniques are usually the pride and fame of the clan that possesses them. The Nara clan's Shadow Imitation Technique and the Aburame clan's Parasitic Destruction Insect Technique are some examples of this. These technique also cannot be copied through any means of simple observation or even with the use of the Sharingan for example.

Trivia

 * They are not to be confused with kekkei genkai, a technique that require a specific genetic ability, as technically, hiden techniques can be taught to anyone.
 * These techniques are more than likely handed down through oral traditions so as not to leave such things as detailed scrolls or documentation behind.
 * Chōza once stated that the Yamanaka clan had mastered hiden techniques. None of the Yamanaka's techniques are currently known to be hiden, and in fact it had been previously stated that the Yamanaka clan's techniques weren't secret techniques.
