Meaning

Optical illusion; hallucination; delusion. Refers to a false perception of reality, whether visual or psychological.

Coined during the Meiji era to render Western psychological concepts. Used both for literal perceptual illusions (optical, auditory) and figurative self-deception — mistakenly believing one is safe, loved, or superior. The verbal form 錯覚する means to be under an illusion. A related phrase is 錯覚に陥る (to fall into delusion).

Examples

1. 遠くの建物が実際よりも近く見えるのは典型的な視覚的錯覚だ。 The appearance of distant buildings as closer than they actually are is a classic visual illusion.
2. 成功が続くと、自分は無敵だという錯覚に陥りやすくなる。 When success continues uninterrupted, it becomes easy to fall into the delusion that one is invincible.
3. 彼は深く愛されていると信じていたが、それはただの錯覚に過ぎなかった。 He believed he was deeply loved, but it was nothing more than an illusion.
