変遷する

• Reading: へんせんする
• Romaji: hensensuru
• Kanji breakdown: 変 (hen) — change, transform; 遷 (sen) — shift, transition, move to
• Pronunciation: /hen.sen.sɯ.ɾɯ/

Meaning

To change; to undergo historical transition; to evolve or shift gradually over time. Refers to meaningful transformation across a defined period.

An irregular Group 3 (suru) verb formed from the noun 変遷 (transition, historical change). Unlike 変化する (which can describe rapid or trivial change), 変遷する implies a more gradual, historically significant evolution — the kind charted in academic papers and historical narratives. Often used with time markers: 時代とともに変遷する (to change with the times). Common in journalism, academic writing, and documentary narration.

Examples

1. 日本の家族観は戦後から現在にかけて大きく変遷してきた。 Japan's conception of the family has undergone significant change from the post-war period to the present.
2. 言語は時代とともに変遷するものであり、百年前の日本語は現代のそれとは大きく異なる。 Language evolves with the times, and the Japanese of a hundred years ago differs greatly from that of today.
3. 技術の発展に伴い、働き方のモデルも変遷を続けている。 As technology advances, the models for how people work continue to evolve.
