After performing the necessary hand seals, a ninja inhales air via their mouth and, utilizing a large amount of fire chakra, spews a large fireball from their mouth, incinerating everything in range. The fireball ignites externally (as evidenced by Kakashi Hatake's ability to use the jutsu without burning his mask). The Uchiha clan uses the technique as a "coming of age" technique. This technique apparently requires more than average chakra reserves and most Genin should not be able to do this technique.
