noun
Used to describe a state of not being active, often in formal or technical contexts such as accounts, memberships, or systems. Less common in casual speech than alternatives like 活動していない.
長期間非活動のアカウントは削除されることがあります。
Accounts that have been inactive for a long period may be deleted.
非活動状態が続くと、システムが自
If the inactive state continues, the system will automatically log you out.
不活動 is a near-synonym also meaning 'inactivity', but 非活動 is more common in modern technical usage. 不活動 may appear in medical or biological contexts.
Formed from the prefix 非 (hi-, 'non-') and 活動 (katsudō, 'activity'). The prefix 非 is commonly used to create nouns meaning 'non-' or 'in-', as in 非公開 (hikōkai, 'private, not open to the public').
