Elemental Jutsu refers to a category of techniques in the Naruto series that utilize the natural elements of fire, water, earth, wind, and lightning. Each ninja can master specific elements based on their chakra nature, which is determined by their innate abilities. These jutsu are used for various purposes, including combat, defense, and support. Ninjas can combine different elemental jutsu to create more powerful techniques, known as Kekkei Genkai. For example, combining water and earth can produce mud, while fire and wind can create a firestorm. Mastery of elemental jutsu is essential for a ninja's growth and effectiveness in battle.
