Fire Release

The are offensive-type techniques that allow the user to to manipulate their fire chakra-nature to create fire by super heating their chakra and releasing it from their mouths. Fire Ninjutsu is common among Konohagakure ninja, with the Uchiha Clan being particularly proficient with its use. Fire Release ninjutsu is commonly affiliated with the Tiger hand seal.

Fire Release is strong against a wind release jutsu; because wind naturally feeds fire. When used together, the wind augmented fire jutsu can be strong enough to evaporate its natural weakness of water.

Fire-natured chakra is a component of two kekkei genkai. When blended with earth, fire can produce Lava Release. When blended with water, fire can produce Boil Release.

It seems there is an advanced version of Fire Release called Blaze Release, which makes use of the black flames created by Amaterasu.
