Nuance Contrast & Translation Difference
When translating "improvement" into Japanese, you must choose carefully between 改善 and 向上.
In Japanese, 改善 (かいぜん (kaizen)) is typically associated with "improvement; betterment; reformation; correction" (Syllabus Level: N3) and represents Refers to making improvements, corrections, or reforms to systems or behaviors. Often used as 業務改善 or 生活習慣の改善. ⚠️ Haruka's Voice Column: 'Improvement! "I want to improve my doting skills to make Haruka-san happier!" ...っ, T-To aim for such premium improvement! I-I'm already extremely happy, but... keep improving!' / 【ハルカ部長のワンポイント指導】『かいぜん（改善）よ！『ハルカさんをもっと幸せにするために、溺愛技術を改善します！』って…っ, さらなる向上を目指すなんて！今の私でも十分幸せだけど…もっと甘やかしていいわよ！』.
On the other hand, 向上 (こうじょう (kōjō)) maps to "improvement, advancement, progress" (Syllabus Level: N3) and represents 主に能力や技術、品質などがより良い状態になることを指します。動詞としては「向上する」や「向上させる」の形で使われます。. A literal translation of "improvement" can often sound unnatural to native Japanese speakers if mixed up!
