Every Jujutsu Kaisen fan who builds an OC hits the same wall: the character has a face, a clan and a grade, and then the technique field sits empty. Searchers type "cursed technique name generator" and "domain expansion name generator" because the show's own names look easy to imitate and turn out to be oddly hard.
Below are 37 techniques and domains from the canon, grouped by type, followed by the patterns that make them sound like they belong in the series.
Canon Cursed Technique Names
A cursed technique is the innate ability a sorcerer or curse is born with. The table lists the name as the fandom uses it, plus the user and one detail from the roster.
| Technique | User / what it does |
|---|---|
| Limitless | Satoru Gojo — the technique behind Infinity, Blue, Red and Hollow Purple |
| Six Eyes | Satoru Gojo — an inherited trait listed alongside Limitless |
| Ten Shadows Technique | Megumi Fushiguro — also tied to the Okkotsu line |
| Blood Manipulation | Yuji Itadori, Noritoshi Kamo and Choso |
| Shrine | Ryomen Sukuna — the technique behind Malevolent Shrine |

Canon Domain Expansion Names
Series lore treats the Domain Expansion as the pinnacle of jujutsu sorcery. These names read nothing like the technique names above, which is the most useful thing to notice.
| Domain | User / what it does |
|---|---|
| Unlimited Void | Satoru Gojo — overwhelms opponents with infinite sensory input |
| Malevolent Shrine | Ryomen Sukuna — omnidirectional slashes across 200 meters |
| Chimera Shadow Garden | Megumi Fushiguro — incomplete when he develops it |
| Authentic Mutual Love | Yuta Okkotsu |
| Idle Death Gamble | Kinji Hakari — a train-station-like environment |
| Self-Embodiment of Perfection | Mahito |
| Coffin of the Iron Mountain | Jogo — a volcanic interior |
| Horizon of the Captivating Skandha | Dagon |
| Shining Sea of Growing Branches | Hanami |
| Deadly Sentencing | Hiromi Higuruma — enforces rulings inside the domain |
| Time Cell Moon Palace | Naoya Zen'in |
Plain Function Words Win for Techniques
Look at the first table again. Ratio Technique, Construction, Comedian, Copy. Most are one or two ordinary words naming what the technique does, or the verb it performs on the world.
That restraint is deliberate in a series where the ability is meant to be figured out mid-fight. A name that explains itself would spoil the puzzle, so the name stays boring and the mechanics carry the surprise.
Domains Run on Poetry
Now the second table. "Horizon of the Captivating Skandha." "Coffin of the Iron Mountain." These are formal, image-heavy phrases, usually a concrete noun of place set against an abstract one.
The pattern holds across the list: a container word (Garden, Palace, Shrine, Coffin, Sea, Horizon) plus a modifier that sounds like scripture or a legal term. A domain is a place, so it gets a place-name.
Three Moves for Your OC's Technique
Start with the mechanic, not the vibe. Write one sentence on what the ability does and what it costs. The name is that sentence compressed to two words.
- Verb the object: Name the thing acted on and the act. "Tool Manipulation" is the model.
- Borrow a trade word: Ratio and Construction come from ordinary vocabulary. Mine hobbies, crafts or bureaucracy.
- Use a person-sized noun: Comedian and Copy sit close to the user's personality, not to a spell book.
The table below shows invented names built with those moves. They are format examples in the series' style, not canon, so the right column describes the concept each implies.
| Invented example | Concept it implies |
|---|---|
| Ledger Technique | Debts accrue on whatever the user touches, then come due |
| Tailor | Cuts and restitches the target's cursed energy flow |
| Metronome | Attacks land on a fixed beat the opponent can learn |
| Inventory | Stores objects and returns them at a cost |
| Understudy | Briefly takes over a shadow of an ally's technique |
| Salt Manipulation | Preserves or corrodes anything it coats |
| Cartography | Marks terrain so the user can swap or recall it |
| Lullaby | Sound that dulls an opponent's reflexes over time |
Domain Names Need a Place and a Rule
Build a domain the other way around. Choose the room first: a courtroom, a harbor, a theater, a flooded library. Then attach the abstract word that states the rule you can't escape.
- Pair a place word with an abstract noun.
- Make the name hint at the sure-hit rule.
- Keep it under six words so it can be shouted.
- Reuse canon domain names with one word swapped.
- Stack three adjectives before the noun.
- Give the domain and the technique the same name.
If you still want a ready-made starting point for the character around the ability, the Jujutsu Kaisen name generator builds the sorcerer's full name, clan and a technique concept to match. For ability names outside this series, the spell name generator works from a broader fantasy register.
Common Questions
Is a cursed technique the same as a domain expansion?
No. A cursed technique is the ability a sorcerer is born with, while a Domain Expansion is a separate advanced move built on top of it, which the series describes as the pinnacle of jujutsu sorcery.
Do JJK technique names have to be Japanese?
No. The English names in the tables are how the series is published in English, and many are plain English phrases like Ratio Technique or Construction. Pick the language that fits your OC's backstory.
Comedian names a personality, not a power. Try guessing what it does from the word alone, and you'll see why the plainest names are the hardest to imitate.
