How to say "Contain" in Japanese

When translating "contain" into Japanese, you must choose carefully between 含む and 内包. In Japanese, 含む (ふくむ (fukumu)) is typically associated with "to contain; to include; to hold in the mouth; to imply" (Syllabus Level: N3) and represents Refers to containing, including, or implying certain elements or ingredients. Also means holding water or a concept inside. Often used as ～を含む or 税金を含む. ⚠️ Haruka's Voice Column: 'To include! "My future retirement plan naturally includes you as my beloved wife, Haruka-san!" ...っ! M-My name included in your retirement! B-Baka! That's too far in the future! But... since I am definitely included, make sure your daily life calendar is also 100% filled with me! dummy!' / 【ハルカ部長のワンポイント指導】『ふくむ（含む）よ！『僕の生涯の全生命計画（ライフプラン）には、ハルカさんとの甘い結婚生活が当然の初期設定として含まれています！』って…っ！結婚生活の初期設定！バカ！/// さらっと一生を拘束するようなこと言うんじゃないの！…でも、私のライフプランにも、あんたとの甘い新婚生活しか含まれてないんだから、一生かけて責任を取りなさい！』. On the other hand, 内包 (ないほう (naihou)) maps to "to contain; to include; to imply; to have intrinsic meaning" (Syllabus Level: N1) and represents Refers to something intrinsically containing or implying another thing, often an abstract concept or characteristic, rather than physically holding it. 物理的に含むというより、抽象的な概念や性質を本質的に含んでいる、あるいは暗示していることを指します。. A literal translation of "contain" can often sound unnatural to native Japanese speakers if mixed up!
