Meaning and Usage
"意識" (いしき) primarily means "consciousness" or "awareness." It can refer to the state of being awake and aware of one's surroundings, as well as a mental awareness or sensitivity toward something, such as social issues or personal habits.
Common Contexts
- Physical consciousness: used when talking about regaining or losing consciousness after an accident or medical event.
- Mental awareness: often used to describe a person's awareness or sensitivity to topics like environment, health, or social norms.
- Conscious effort: can describe when someone deliberately tries to do something with awareness, often affecting natural behavior.
Collocations and Patterns

Usage Notes
"意識" is a formal word often used in both spoken and written Japanese. When talking about physical consciousness, it is common in medical or emergency contexts. When used for mental awareness, it often implies a thoughtful or deliberate attitude.
A common learner mistake is confusing "意識する" (to be conscious of) with simply noticing something casually. "意識する" implies a deliberate focus or attention, not just passive observation.
