Taiyōjutsu

Taiyōjutsu is regarded as the highest level of Senjutsu; theorized and developed by Seireitou Hyūga, its only known user. Sage techniques are different from standard ninjutsu and genjutsu because they utilize a chakra crafted from spiritual and physical energy mixed together with natural energy. The latter form of energy is drawn from nature itself, as the name implies, which composes the environment that surrounds the Sage. However, despite the vast power that exists on this spectrum, this natural energy is but a significantly minuscule fragment of where natural energy finds its origins. All life on the planet begins with the, which means that the Sun itself is the single most abundant source of natural energy available and where all life on the Earth finds its own natural energy; as the plants draw their food source from the Sun, while living beings such as humans and animals later obtain their food source from those very plants; whether by direct or indirect means. In a way, one can relate the Sun to natural energy as the God Tree is the originator to all chakra.

When one masters Senjutsu to its highest level, as Seireitou has explained, one becomes capable of drawing upon the true source of all natural energy: the Sun itself. By being able to draw upon this immense source of natural energy, one's Senjutsu completely transcends its prior limitations and becomes something new entirely. However, the most amazing attribute of the Taiyōjutsu is that by learning to harness the Sun's power, one can accomplish several feats that involve utilizing its heat: such as pulling on a solar flare and causing the entire landscape to erupt into wild flames.
