Lava Release (熔遁; 溶遁 Youton) techniques combine fire and earth-based chakra to create a torrent of lava that can melt away almost anything. This chakra nature can also manipulate other related materials such as lime, which is an alkaline powder, rather than molten rock. Lava Release is used by the Four-Tailed Monkey, its jinchuriki Roushi, and is one of the kekkei genkai used by the Fifth Mizukage, Mei Terumi and the Third Tsuchikage's granddaughter, Kurotsuchi.
Lava Release can be written in two different ways: Roushi's Lava Release is referred to by the kanji 熔, with the radical for "fire" (火), while Mei's is referred to by the kanji 溶, with the radical for "water" (水) instead. When Kurotsuchi used it, it was once again with the fire radical. This seems to indicate that the Lava Release from Iwagakure uses the fire radical, while the Lava Release from Kirigakure uses the water radical. However, in the data and fan books, both kanji have been used to refer to Roushi's Lava Release. Both of them are in fact synonyms for each other and are interchangeably, though the one that's used the most is 溶. It seems that the kanji with the fire radical is used more often in words relating to metal and other solids, whereas the kanji with the water radical is more often used in words relating to liquids. In the manga three variations of the element have been shown so far: normal lava, rubber and quicklime.
