na-adjective, noun
uncontrolled; unregulated; lacking control
Describes a situation, system, or behavior that is not properly managed or supervised, often with a negative connotation of disorder.

Uncontrolled development is destroying the environment.
その組織は無統制の状態だ。
The organization is in an unregulated state.
野放図 also means 'uncontrolled' or 'unrestrained', but often implies a more wild or reckless lack of restraint, while 無統制 emphasizes the absence of systematic regulation.
Formed from 無 (mu, 'without') + 統制 (tousei, 'control, regulation'). The exact historical derivation is uncertain, but the word follows a common pattern of negating a noun with 無.
