Jutsu

Before modern ninjutsu, Hagoromo Ōtsutsuki taught ninshū (忍宗)—a way to help people understand themselves and others and to seek peace. Over time those teachings were refined into combat arts, and the weaponised practice became what villages call ninjutsu today.

Most fighting styles fall under three broad headings: ninjutsu, genjutsu, and taijutsu. Many specialisations exist underneath—sealing, curses, sage techniques, and more. Kekkei genkai are inherited traits; they are not “just another jutsu category,” but they often enable signature techniques (for example, combined nature releases).

Without solid chakra control, techniques weaken or fail, and a shinobi burns through their reserves too quickly. Hand seals are a common way to regulate flow and shape an effect efficiently; different techniques expect different seal chains.

Hand seals (印, in) are finger positions ninja weave to help mould, stabilise, and time chakra for a technique. Most ninjutsu use a sequence of signs in a set order; longer or trickier chains often go with more complex or powerful effects, and skilled shinobi sometimes shorten the chain or use one-handed variants when their control is strong enough.

The twelve standard seals follow the Chinese zodiac (the same twelve animals in the same order English wikis use: Rat through Boar). That order is a shared vocabulary—like a "keyboard" for chakra—not a single recipe for every jutsu.

What about elements? A technique's element (Fire Release, Water Release, etc.) comes from nature transformation—what kind of chakra nature you knead into the technique. Hand seals shape the flow; they are not a 1:1 "this seal always means fire" rule in the story. The same seal can appear in different elemental techniques; databooks list Nature and seals as separate fields. For how the five basic natures interact and how combined releases work, read Chakra natures.

Yin, Yang, and non-elemental arts: Genjutsu, medical ninjutsu, body modification, sealing, and many hiden still use seals (or specialised alternatives like the Seal of Confrontation); their "element" is often Yin/Yang or not elemental in the five-nature sense, even though the twelve-animal signs stay the common building blocks for moulding.

The twelve signs (standard order)

Ninji's technique form uses these English names, matching major wikis. Romaji + kanji are the usual zodiac readings. The affiliations column summarises patterns you often see in guides (clan arts, common nature pairings)—they are not absolute rules; any seal can appear in many techniques.

When you submit or edit a technique, you can build a seal chain from this list (or enter free text for counts, mixed kanji, or notes).

Techniques are often graded by difficulty and risk. This is separate from shinobi rank (genin, chūnin, jōnin, etc.)—think of these letters as “how hard or dangerous the technique is,” not the ninja's job title.

• E-rank — Academy-level fundamentals; basics every shinobi learns.
• D-rank — Typical genin-level techniques; many ninja specialise rather than learning every D-rank art.
• C-rank — Often associated with chūnin-level skill; talented genin may reach some of these with extra training.
• B-rank — Jōnin-tier difficulty; usually demanding chakra pools and control.
• A-rank — Advanced jōnin or Kage-calibre; may be restricted or forbidden.
• S-rank — Secret or extreme techniques, often tied to a single lineage or user.

Many kekkei genkai and unique abilities are not given a standard letter rank at all—they are treated as their own class of threat and rarity.

The three pillars below are the usual starting point when sorting techniques. Each has a card in Technique categories with links for deeper reading.

• Ninjutsu — The broadest bucket: chakra techniques that are not genjutsu or taijutsu. Many use seals; some rely on tools or staged setups instead.
• Genjutsu — Illusions that target the senses; the harm is perceived rather than always physical. Often discussed alongside Yin-nature ideas in lore.
• Taijutsu — Body arts: strikes, throws, movement, and conditioning. Chakra may enhance taijutsu, but many forms are fast and seal-light compared to ninjutsu.

The grid below groups many of these labels. Examples you will see in stories and databooks include barrier ninjutsu, weapon arts (bukijutsu, kenjutsu, shurikenjutsu, etc.), sealing (fūinjutsu), curse seals (juinjutsu), collaboration techniques, clone methods, space–time ninjutsu, medical ninjutsu, senjutsu, and forbidden techniques (kinjutsu). Novels sometimes mention escape-focused arts grouped as tonjutsu.

Kekkei genkai are heritable anomalies that unlock unique techniques or body traits, usually within a clan line. Kekkei tōta is even rarer (three-nature fusions). Kekkei mōra appears in Ōtsutsuki-line lore as a broader inherited tier. Dōjutsu covers eye techniques—both passive ocular abilities and the high-cost jutsu that rely on those eyes (transplants work, but often with extra strain).
