Ice Release (氷遁, Hyōton) allows users to combine wind and water-based chakra to create ice, which they can manipulate through willpower alone. The ice created is largely immune to fire-based attacks, only melting slightly when coming into contact with flames.
Several of the Yukigakure ninja also have the ability to use Hyoton techniques. However, this was not the product of a similar kekkai genkai, as demonstrated by Kakashi's ability to replicate one of these jutsu with his Sharingan. In addition, unlike those who possess the bloodline who could create their own ice, the Hyoton jutsu used required the users to manipulate already existing ice. The Yukigakure ninja used hand seals in their ice manipulation abilities. These ice release or Hyoton techniques commonly used the Hand Seal: Dog.
It is also a chakra nature used when one is the host of the Three-Tailed Giant Turtle, though the turtle's version seems to be less effective than the Kekkai Genkai, only allowing creation of mist as far as ice creation goes. However, unlike the kekkai genkai it makes the user's chakra appear cold and icy.
Another known use of this release is through the Korino clan's kekkei genkai. Through this bloodline, they can manipulate their water nature with unnaturally cold temperatures stored in their chakra. This form of ice is strong enough to rival even a diamond in durability.
