  • 解体かいたいCommon

  • 解散かいさんJLPT N2approx.Common
    noun, suru verb, transitive verb, intransitive verbThe usual word for the dissolution of a company, organization, parliament, or group, meaning it formally ceases to exist or disbands. It is the natural choice when no nuance of dismantling is intended.

Use 溶解 for chemical dissolving, 解散 for dissolving organizations or companies, and 解体 for breaking such bodies up; the last two overlap but 解体 stresses dismantling.
