Meaning

Annexation; merger; incorporation. The act of absorbing one territory, state, or organisation into another, often by force or political pressure.

Carries strong historical and political weight in Japanese, particularly in the context of colonial history (e.g. 韓国併合, the annexation of Korea in 1910). In contemporary usage it may describe corporate mergers or administrative consolidations, but retains connotations of asymmetric power when used in geopolitical contexts. Distinguished from 合併 (gappei, merger of equals) by implying absorption by a dominant party.
