Wood Release: Wood Dragon Technique

After preforming the required hand seals, the user creates an immense wooden Chinese dragon with the trunk of an elephant from the ground directly below them. The dragon can then attack the intended target from a long range. According to Madara Uchiha, during his fight with Hashirama Senju, the Hokage used it to restrain Kurama.

Influence
The dragon created with this technique resembles a creature predominantly seen in Hindu mythology known as Makara. The myth surrounding this creature has spread throughout most of Asia, however, and in Chinese renditions of the creature it most resembles this one — a dragon with an elephant's trunk.

Trivia

 * In an anime cutscene of Tobi's storyline in Naruto Shippūden: Ultimate Ninja Storm Generations, it was shown that the Hokage-Style Sixty-Year-Old Technique — Kakuan Entering Society with Bliss-Bringing Hands was used to restrain Kurama during the battle between Hashirama and Madara. In chapter 607, however, Madara stated that the Wood Dragon was used to restrain Kurama during their battle.
