Words for safety and security

Japanese has several words for safety and stability, each differing in meaning and nuance.

大丈夫 (All right)

大丈夫(だいじょうぶ) is a broad word for saying that something is fine or not a problem. Context determines the meaning, so 大丈夫 covers more ground than the other words in this group.

安心 (Peace of mind)

安心(あんしん) describes freedom from anxiety. It names the calm one feels when they believe things are secure. Since that feeling depends on the individual’s experience and circumstances, one person can feel 安心(あんしん) in a situation that still worries someone else.

平気 (Composed)

平気(へいき) describes someone who stays unaffected or unbothered by something that might cause worry. It describes whether a situation has danger. 平気(へいき) focuses on the person’s reaction, so someone can be 平気(へいき) even in an uncomfortable situation.

無事 (Safety)

無事(ぶじ) describes coming through something without injury or trouble. It is used after danger or uncertainty has passed to confirm that nothing bad happened.
