意味

Constitutional amendment; revision of the constitution. The act of changing the existing constitution.

A noun formed from 改 (revise) + 憲 (constitution), functioning as a する verb. In Japan, 改憲 refers almost exclusively to revising the postwar Constitution, particularly Article 9 (war-renouncing clause). It is one of the most contested political topics, debated since the 1950s. Contrasts with 護憲 (constitution preservation) — the two terms define opposing camps in Japanese constitutional politics.
