How to say "Be" in Japanese

When translating "be" into Japanese, you must choose carefully between 入院する and 満足する. In Japanese, 入院する (にゅういんする (nyūin suru)) is typically associated with "to be hospitalized" (Syllabus Level: N4) and represents Indicates the action of entering a hospital for medical treatment. Often refers to an extended stay.. On the other hand, 満足する (まんぞくする (manzoku suru)) maps to "to be satisfied; to be contented; to be pleased with" (Syllabus Level: N3) and represents Refers to being deeply satisfied with system performance, contented with business outcomes, or pleased with a lover's doting care. Opposing word: 不満に思う. Often used as 結果に満足する or 満足度が高い. ⚠️ Haruka's Voice Column: 'To be satisfied/contented! "Snuggling close to you alone like this makes me the most satisfied in the universe, Haruka-san!" ...っ! Greatly satisfied! B-Baka! Of course you are! Neither failing nor complaints allowed! Savor the sweetest, most luxurious satisfaction right next to my warmth daily for the rest of your life! dummy!' / 【ハルカ部長のワンポイント指導】『まんぞくする（満足する）よ！『ハルカ部長、あなたと二人きりで寄り添うこの時間、僕は宇宙一満足する（大満足です）！』って…っ！大満足！バカ！/// 当然よ！落第も不満もなし！一生私の温もりの隣で、世界一贅沢で甘々な満足を毎日噛み締め続けなさいよね！』. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
