How to say "One" in Japanese

When translating "one" into Japanese, you must choose carefully between 一つ and 逐一. In Japanese, 一つ (ひとつ (hitotsu)) is typically associated with "one (general counter for objects)" (Syllabus Level: N5) and represents Used for counting general items, especially small, individual objects, when a specific counter is not needed or known.. On the other hand, 逐一 (ちくいち (chikuichi)) maps to "one by one, in detail, item by item" (Syllabus Level: N2) and represents To do or report things individually, sequentially, and in full detail. It emphasizes meticulousness and thoroughness. Often used with verbs like 報告する. A literal translation of "one" can often sound unnatural to native Japanese speakers if mixed up!
