有事

• 読み: ゆうじ
• ローマ字: yūji
• 漢字の分解: 有 (yū/a) — have, exist; 事 (ji/koto) — matter, affair, event
• 発音: /jɯː.dʑi/

意味

Emergency; contingency; wartime; crisis. A state of exceptional circumstances, especially armed conflict, serious security threat, or major national disaster requiring special governmental response.

Contrasted with 平時 (heiji, peacetime/normal times). The term gained prominence in Japan through debates over 有事法制 (emergency legislation), enacted in 2003, which defines governmental powers during armed attack situations. 有事 carries an urgency and gravity not present in general terms for emergency (緊急事態, 非常事態). In security discourse, 台湾有事 (a Taiwan contingency) has become a key phrase in discussions of regional stability.

例文

1. 有事の際に政府がいかに迅速かつ適切に対応できるかが、安全保障の要となる。
2. 台湾有事への備えとして、日米同盟の強化が急務だと防衛省は訴えた。
3. 平時には見えにくい制度の脆弱性が、有事においてはっきりと露呈することがある。
