Translation guide
The English word 'uncanny' describes something strange, mysterious, or unsettling in a way that feels familiar yet wrong. In Japanese, there is no single perfect equivalent. Instead, learners should choose expressions based on the nuance: eeriness, supernatural strangeness, a sense of something being off, or remarkable skill.
To describe a situation, place, or person that feels creepy, weird, or gives an uneasy feeling, often with a hint of the supernatural.

Means 'to a mysterious degree'. Used when something is so accurate or fitting that it feels strange or inexplicable.

Means 'mysterious and strange', often with a supernatural or bizarre nuance. Used in terms like 怪奇現象 (strange phenomena).

While 不気味 is the closest general word, it mainly covers the 'creepy/eerie' sense. For 'uncanny ability' or 'uncanny resemblance', use phrases like 驚くほど正確な or 不思議なほど. Using 不気味 for a skill would sound like the skill itself is creepy, which is usually not the intent.

His memory is creepy. (Not the intended meaning of 'uncanny' here.)
不気味 is the standard, somewhat objective term for eeriness. 気味が悪い is more subjective and conversational ('gives me the creeps'). 薄気味悪い is a literary, slightly vague version ('faintly creepy'). Choose based on formality and how personal the feeling is.

He has an uncanny ability to predict the future.
不思議な能力 is a natural collocation for 'uncanny ability'.
