Core Principles

Ninjutsu is one of the three foundations of a ninja’s combat ability, alongside Genjutsu and Taijutsu. Its effectiveness depends on available Chakra, chakra control, nature transformation, and shape transformation 45 254.

Chakra is formed by combining physical energy and spiritual energy. A ninja’s reserves therefore depend on both physique and mental power 5 38.

Chakra Natures

Nature	Documented properties	Interaction
Earth Style	Stable, durable, and convenient to use where soil or dust is present. Gong Yi’s strongest affinity is Earth 45 85.	Counters Water Style 45.
Water Style	Can be hard or soft and has highly variable forms 45.	Counters Fire Style 45.
Fire Style	Typically wide-area and intensely hot; Konoha is especially known for it 45.	Counters Wind Style 45.
Wind Style	Sharp and suited to cutting attacks 45.	Counters Lightning Style 45.
Lightning Style	Fierce and violent; often used for piercing, paralysis, or amplification through water 45 188.	Counters Earth Style 45.
Yin Release	Uses spiritual or mental energy. Genjutsu, the Nara Clan’s Shadow Secret Technique, and Yamanaka techniques are identified as Yin Release applications 110.	—
Yang Release	Uses physical energy. The Akimichi Clan’s Multi-Size Technique and Tsunade’s Strength of a Hundred are cited as examples 110.	—

The convergence of Yin and Yang produces attribute-less Chakra, while affinity for a given nature makes its transformation easier to learn 110.

Shape and Nature Transformation

Nature transformation gives Chakra an elemental property, while shape transformation determines its form and application. Fully mastering shape transformation can qualify a technique as A-rank; the Rasengan is described as its pinnacle and requires no hand seals 11.

Low-rank techniques also contain shape transformation. Gong Yi initially reduced Chakra expenditure by cutting unnecessary shaping from techniques such as Earth Style Wall, leaving it less refined but more efficient 11 45.

Rank and Strategic Value

A technique’s rank is not a simple measure of whether it will win a fight. Destructive output, release conditions, learning difficulty, Chakra cost, physical backlash, and timing all affect its practical value 5 220.

Rank	Documented examples	Notes
C-rank	Earth Style: Earth Style Wall; basic elemental techniques	The Earth Style Wall uses five seals—Rat, Ox, Monkey, Boar, and Bird—and prioritizes survival over offense 9.
B-rank	Rock Armor; Earth Style: Sharp Spear; Fire Style: Majestic Destroyer Flame	Rock Armor was self-created by Gong Yi. Sharp Spear and Majestic Destroyer Flame were later refined into super-fast one-handed techniques 37 70.
A-rank	Rasengan; Earth-Splitting Palm	Rasengan is seal-less and relies on extreme rotational shape transformation. Earth-Splitting Palm concentrates Chakra into the palm to shatter the ground and can restrict an enemy’s escape 11 55.
S-rank	Flying Thunder God; Earth Style: Mountain Collapse; Heaven-Turning Palm; Glazed Sky Curtain	S-rank techniques may be classified for learning difficulty and bodily burden as well as destructive power 74 220 228 257.

Casting Methods

Hand Seals

Hand seals facilitate Chakra flow and speed up release, but they are not inherently mandatory. With sufficient Chakra control, a user can simplify seals, use one hand, or omit seals entirely 70.

• Standard seals — The usual method for directing Chakra into a technique 9 70.
• Simplified seals — Reduce the number and complexity of movements required 70.
• One-handed seals — Demand exceptional Chakra control and significantly improve release speed 70.
• Seal-less release — Removes visible seals but can be too slow for combat if Chakra must be gathered over a long period beforehand 70.

Divine Sense Imprints

Gong Yi later developed a more reliable instant-casting method through Divine Sense Seeds. A technique must first be mastered to the level of one-handed seals before it can be imprinted 188.

• A single Divine Sense Seed can hold up to five Ninjutsu imprints 188.
• Activating an imprint produces a seal-less, instant release 188.
• Gong Yi first demonstrated this with Earth Style: Sharp Spear, materializing a three-meter spear instantly 188.

Transmission and Development

Ninjutsu is ordinarily obtained through clan inheritance, master-disciple teaching, or village mission rewards. Civilian students generally receive only the Three Body Technique because they lack bloodlines, resources, and the Chakra reserves needed for stronger techniques 4 5.

Konoha’s extensive Ninjutsu collection began under the Second Hokage, who considered broad technical knowledge necessary for developing new techniques. The Third Hokage continued this work, contributing to his reputation as the “Professor of Ninjutsu” 67.

Medical Ninjutsu is particularly useful for research because anatomical knowledge and precise Chakra control support the creation and refinement of other techniques 67.

Gong Yi’s Ninjutsu Research

Milestone	Chapter	Result
Learned Earth Style: Earth Style Wall from Ishii Kawa	9	Mastered the C-rank defensive technique within ten days; his Chakra capacity initially prevented him from creating multiple walls like his teacher.
Received his first research topic	11	Tasked with reducing Earth Style Wall’s Chakra cost by half without reducing its power; after one month, he achieved an irregular wall using one-fifth less Chakra.
Optimized low-level techniques	12 37	Reduced Chakra consumption by half for Earth Style Wall, Headhunter Jutsu, and Rock Pillar Spear.
Created Water Formation Wall	32	Derived a Water Release defense from Earth Style Wall; its power was comparable to a B-rank technique.
Mastered Earth-Splitting Palm	55	Spent more than three months overcoming the technique’s Chakra backlash and learning to restrain targets from escaping.
Refined B-rank techniques for rapid casting	70	After six months, developed super-fast simplified one-handed versions of Sharp Spear and Majestic Destroyer Flame.
Created Gold Style	141 142	Developed a Kekkei Genkai by fusing Earth and Fire Chakra; its early applications emphasized speed and sharpness.
Developed instant Ninjutsu imprints	188	Used Divine Sense Seeds to enable seal-less, instant casting for up to five mastered techniques.
Created Heaven-Turning Palm	220	Years of Earth Style cultivation produced an S-rank technique combining advanced shape and nature transformation.
Developed Glazed Sky Curtain	257	Researched an S-rank Water Release defense with sufficient Sage Mode enhancement to withstand Deidara’s ultimate self-destruction.
Achieved Flying Thunder God teleportation	271	Successfully teleported to a marked Kunai fifty meters away after adapting the technique to his own method.

Advanced Applications

Kekkei Genkai

Kekkei Genkai can arise from combining basic Chakra natures. Gold Style, created by Gong Yi through Earth and Fire Chakra, can form golden Kunai, longswords, body coatings, and large-scale attacks 141 142 158 222.

• Gold Style Kunai — Increased from eight to ten manifested weapons after further development 158.
• Gold Style longsword — A signature shape-transformation application used against the AB Duo 158.
• Sword River — A Gold Style killing move capable of resisting a Tailed Beast Bomb 222.
• Sword Realm — A large-scale sword-based Ninjutsu used to trap and defeat the Eight-Tails 236.

Sage Art

Sage Art combines Natural Energy with Chakra and can greatly amplify Ninjutsu. It requires enormous Chakra reserves; insufficient control can cause the user to be devoured by Natural Energy 131 178.

Gong Yi’s Snake Sage Art is especially suited to enhancing Ninjutsu power, allowing him to employ large-scale techniques and maintain combat pressure against armies and Tailed Beasts 209 228 229.

Combination Ninjutsu

Multiple elemental techniques can be combined to enhance power or cover weaknesses.

• Water Release + Lightning Style — Water can expand Lightning Style’s effective area, as seen in Lightning Flash Electric Pattern and Sage Art: Exploding Vortex Water Blade 102 319.
• Earth Style + Fire Style — Forms the basis of Gong Yi’s Gold Style Kekkei Genkai 142.
• Multi-user elemental barrages — Konoha formations can combine Wind, Lightning, Water, Fire, and Earth techniques for overwhelming battlefield coverage 102.

Notable Techniques

Technique	Type	Function
Three Body Technique	Basic Ninjutsu	Includes Clone, Transformation, and Substitution Techniques; Gong Yi reached near-instant use early in his academy career 5.
Earth Style: Earth Style Wall	C-rank Earth Style	Raises thick defensive earthen walls; its defensive value and improved Chakra efficiency made it a core survival technique 9 11.
Water Formation Wall	Water Release defense	A B-rank-comparable barrier derived from Earth Style Wall 32.
Rasengan	A-rank shape transformation	A seal-less rotating Chakra sphere with immense tearing force 11 59.
Earth-Splitting Palm	A-rank Earth Style	Shatters the ground through palm-delivered Chakra and can trap targets in closing fissures 55 81.
Lightning Style: Dragon-Binding Pillar	Lightning Style restraint	Creates lightning pillars that paralyze and bind targets 188 319.
Wind Style: Vacuum Severing Dance	Wind Style offense	A long-range cutting technique noted for its power and battlefield reach 188.
Flying Thunder God Technique	S-rank Space-Time Ninjutsu	Teleports the user to marked locations; Gong Yi initially struggled with it before adapting his own method 74 269 271.
Earth Style: Mountain Collapse	S-rank Earth Style	Triggered a volcanic eruption that destroyed Kumogakure’s vanguard 228.
Glazed Sky Curtain	S-rank Water Release	A high-coverage defensive technique strengthened dramatically by Sage Mode 257.

Limitations

• Chakra capacity determines how often and how extensively Ninjutsu can be used; Gong Yi could initially make only one Earth Style Wall while Ishii Kawa could create several 9.
• Environmental conditions can weaken a technique. Water Release was heavily constrained in the desert, where users required scrolls to supply water 59.
• Elemental restraint relationships matter, but a large enough difference in power can override them 45.
• Earth Style techniques can have severe speed limitations; Mountain Collapse was devastating against concentrated forces but less effective after Kumogakure dispersed 228.
• High-level techniques may injure their user through Chakra backlash. Gong Yi repeatedly damaged his hands while learning Earth-Splitting Palm and required the Healing Technique to continue training 55.
