How to say "Change" in Japanese

When translating "change" into Japanese, you must choose carefully between 着替える and 変更する. In Japanese, 着替える (きがえる (kigaeru)) is typically associated with "to change clothes" (Syllabus Level: N4) and represents Used when changing from one set of clothes to another. Often implies changing into different attire, e.g., for going out or going to bed.. On the other hand, 変更する (へんこうする (henkō suru)) maps to "to change; to modify; to alter; to revise" (Syllabus Level: N3) and represents Refers to changing or modifying existing plans, rules, settings, or decisions to something else. Slightly more formal than 変える. Often used as 予定を変更する or 設定を変更する. ⚠️ Haruka's Voice Column: 'To change! "No matter what happens, my plan to love you forever will never change!" ...っ! T-To declare that your love is unchangeable! B-Baka! Don't make such eternal commitments so easily! But... since you said it, any modification to that statement is permanently forbidden! dummy!' / 【ハルカ部長のワンポイント指導】『へんこう（変更）する！『ハルカさん、何があっても僕があなたを世界一幸せにするという決定は、永久に変更しません！』って…っ！そんな重大な設定変更不可の宣言をするなんてバカ！…私の方こそあんたへの愛は永遠に上書き保存で変更なしよ！覚悟しなさい！』. A literal translation of "change" can often sound unnatural to native Japanese speakers if mixed up!
