After forming the required hand seals, the user creates an enormous statue-like creature out of wood. This humanoid creature with a full body and an oni-like face is usually created with a wooden dragon wrapped around its torso, and is generally used in battle as an avatar. The wooden dragon can be multiplied and be used to attack its enemies directly as well. This creature is stated to be as powerful as the Nine-Tails, and could catch an uncompressed, uncharged, standard Tailed Beast Ball fired by the latter. If the user doesn't have enough time to manifest the entire body, they can manifest a limb or two first to buy enough time for the full body to form.  It could even clash against the likes of Madara Uchiha's Complete Body — Susanoo, which was stated by Madara himself to have destructive powers rivalling even the tailed beasts.
In the anime, it is capable of spawning multiple Wood Dragon heads, each capable of self-destructing.
This technique seems to be based upon Ryūtōki (竜燈鬼, Dragon-Lamp Demon), a creature from Japanese folklores, who is typically depicted as a small oni with a dragon coiled around its torso. Together with Tentōki (天燈鬼, Heavenly-Lamp Demon), the pair symbolise the power of the Shitennō to repel and defeat evil.
The Buddhist monk Kōben sculpted notable wooden statues of both Tentōki and Ryūtōki, which are each considered a National Treasure of Japan.
