Commonly known as Hiden, the secret techniques in Naruto have mostly been confused with the classification of Kekkei Genkai. However, these techniques remain confidential within the clan and are passed down from generation to generation only to the members. These techniques are so complex that even a Sharingan user can't observe them.
Although these techniques remain a secret and clan members are prohibited from revealing them to others, they can be taught if the user is willing. While most of the secret techniques that have been featured in Naruto are rooted in Yin or Yang Release, a few of them are a combination of Fuinjutsu and Kekkei Genkai.

10) Face Copying Technique
Face Copying Technique is a formidable version of the Transformation technique, commonly associated with the Kedoin clan in Naruto. It's considered flawless because even a Ninken won’t figure out the person's actual identity using the Face Copying Technique by smelling the scent.

The Fury technique is one of the deadliest techniques in Naruto that didn’t receive the spotlight it deserved. This technique was developed by En no Gyoja and his granddaughter Hotaru and passed down to his cherished student Hato. Before Hato could entrust Fury to his son Shiranami, he killed him and obtained it.

Shiranami was a highly skilled and immensely talented shinobi as he enhanced Fury with his Tsuchigumo Style: Forbidden Life Technique Release: Creation of Heaven and Earth.
8) Curse Mandala
Curse Mandala is considered an ancient ninja art that only a few members of the Fuma clan were able to master. The only known user of this technique in Naruto was Arashi. The user traps their opponent in a chakra-infused pyramid-shaped cage to perform this technique.
After imprisoning the target, users of this technique can shrink the size of the pyramid by bringing their hands together. However, if the user fails to maintain the pyramid or if their targets somehow break free, it causes the cage to explode. Users caught up in the explosion deal with serious injuries, but the target in the middle of the cage remains safe without a scratch.

The Akemichi clan is one of the noble clans of Konoha, renowned for their ability to manipulate the size of their body in Naruto. The clan members keep themselves fat by overeating to store calories, which they will convert into chakra to perform overwhelming Calorie Control techniques.
One of the most powerful abilities of Calorie Control is the Butterfly Mode, which requires a large amount of chakra and subsequently shrinks the size of the user. Most members use Three Colored Pills to initiate this technique as it converts excess fat rapidly. Users gain a tremendous boost in their overall strength by transforming into Butterfly Mode.
4) Mind Body Switch Technique
The Mind-Body Switch Technique is the hallmark of the famed Yamanaka clan in Naruto. Unlike other techniques in Naruto, the Mind-Body Switch is neither offensive nor defensive, as the user performs this technique to transfer their consciousness onto their targets and take control of their entire body.
After successfully executing Mind Body Switch, the user’s body enters into suspended animation. The Yamanaka clan mainly uses this technique to gather intel and interrogate the targets in the Konohagakure Intelligence Division.
3) Shadow Imitation Technique
The Shadow Imitation technique is a powerful secret technique of the Nara clan, who are known for manipulating shadows with their Yin Release. Users of this technique can merge their shadows with their targets to completely restrain their movements and control their target’s body like a puppet.
Although it limits overstretching their shadows and holding their targets, some highly skilled members of the Nara clan in Naruto, like Shikamaru, can overwhelm their targets for an extended period.
The clan members have also created deadly variants of this technique like the Sewing Technique and the Neck Binding Technique, which can kill the targets in the blink of an eye.

1) Wood Release Secret Technique: Nativity of a World of Trees
The only person who has mastered Wood Release in the entirety of Naruto is the legendary first Hokage Hashirama Senju. After so many efforts to reproduce this Kekkei Genkai, only Yamato managed to inherit it. However, his versatility and prowess with Wood Release still don’t match with the likes of Hashirama.
Although there have been numerous Wood Release techniques, only one manages to fall into the category of secret techniques: the Wood Release Secret Technique: Nativity of a World of Trees. Using this technique, the user summons rapidly growing dense trees that can capture the target to constrain them and drain their chakra reserve entirely and partially, which depends on the user's will.
