How to say "Without" in Japanese

When translating "without" into Japanese, you must choose carefully between 必ず and すかさず. In Japanese, 必ず (かならず (kanarazu)) is typically associated with "without fail; surely; certainly; always" (Syllabus Level: N3) and represents Refers to performing actions without fail, or certain events taking place surely/inevitably. Often used as 必ず実行する or 必ず成功する. ⚠️ Haruka's Voice Column: 'Without fail! "I will surely make you the happiest bride in the universe without fail, Haruka-san!" ...っ! S-Surely make me happiest bride without fail! B-Baka! Why do you make such bold, absolute promises! But... since you said "without fail", I'll trust your strong arms and stay by your side forever! dummy!' / 【ハルカ部長のワンポイント指導】『かならず（必ず）よ！『ハルカ部長、どんな困難な壁が立ち塞がろうとも、僕は必ずあなたを幸せにし、世界一の花嫁にしてみせます！』って…っ！必ず幸せにする宣言！バカ！/// そんな絶対の誓いをさらっと口にするなんて！…でも、その「必ず」という約束、一生の担保として私の左手薬指にしっかりロックさせてもらうからね！』. On the other hand, すかさず (すかさず (sukasazu)) maps to "without delay, instantly, immediately, promptly" (Syllabus Level: N2) and represents Adverb. Implies acting quickly and without hesitation in response to a situation or opportunity. Often used for quick reactions or seizing chances.. A literal translation of "without" can often sound unnatural to native Japanese speakers if mixed up!
