Translation guide
The act of incorporating territory into another state, often by force. In Japanese, the core term is 併合 (へいごう), but other words like 編入 (へんにゅう) and 合併 (がっぺい) are used depending on context, such as administrative mergers or corporate acquisitions.
To express the political or military incorporation of one territory into another country.
The standard term for annexation of territory, especially by force or unilateral action. Often used in historical and political contexts.

Refers to incorporation or admission into an existing administrative unit, often with a sense of formal integration. Can be used for territorial annexation but is less forceful than 併合.

Primarily means merger, especially of companies or municipalities. Can be used for territorial annexation when two entities merge voluntarily, but not for forced annexation.

To describe the incorporation of land into a city, town, or other administrative district, often through legal processes.
The most common term for annexation of land by a municipality. Implies a formal, often legal, process of adding territory.

Used when two or more municipalities merge to form a new entity. Not exactly annexation, but often translated as such in English contexts.
To express the idea of taking over or appropriating something non-territorial, such as ideas, roles, or responsibilities.
When 'annexation' is used metaphorically to mean seizing control, 乗っ取り (のっとり) or 横取り (よこどり) are more natural than direct translations of annexation.
彼はプロジェクトを乗っ取ろうとしている。
He is trying to annex the project.
Can be used figuratively in formal contexts, but may sound stiff. Best reserved for territorial or organizational contexts.

併合 (へいごう) implies forced or unilateral annexation, often by a state. 編入 (へんにゅう) is a neutral term for incorporation into an existing unit, common in administrative contexts. 合併 (がっぺい) is a merger of equals, used for companies or municipalities. Choose based on the power dynamic and formality.
English 'annexation' can be used loosely (e.g., 'annexation of responsibilities'). In Japanese, 併合 is rarely used this way. Instead, use verbs like 取り込む (とりこむ) or 乗っ取る (のっとる) depending on nuance.
