Yuji Domain Expansion is an advanced innate technique in the Jujutsu Kaisen anime that allows jujutsu sorcerers to manifest their cursed powers to the utmost limit within a separate space. It is achieved by expanding ones innate domain with cursed energy while using a barrier to construct it inside a separate space. The caster then imbues their cursed energy into the space, creating a unique environment that is tailored to their specific abilities.
According to the search results, Yuji Itadori does not have a Domain Expansion yet. However, some fans speculate that he might be able to unlock it in the future.
