noun
overall peace treaty; comprehensive peace
Refers to a peace agreement that covers all parties and issues, not a partial or separate peace. Often used in historical and diplomatic contexts.
戦後、連合国と日本の間で全面講和が結ばれた。
After the war, an overall peace treaty was concluded between the Allied Powers and Japan.
Compound of 全面 (zenmen, 'all sides, whole area') and 講和 (kōwa, 'peace, reconciliation'). The exact historical derivation is uncertain, but the term is conventionally used for a comprehensive peace settlement.
