How to say "Person" in Japanese

When translating "person" into Japanese, you must choose carefully between 係 and 関係者. In Japanese, 係 (かかり (kakari)) is typically associated with "person in charge, attendant, charge, duty" (Syllabus Level: N4) and represents Refers to a person assigned a specific task, role, or duty within a group, organization, or event. On the other hand, 関係者 (かんけいしゃ (kankeisha)) maps to "person concerned; interested party; official; insider" (Syllabus Level: N3) and represents Refers to people who are involved in, related to, or have a connection with a particular matter, event, or organization. Often used in formal contexts, news reports, or discussions about projects/incidents. 関係者以外立ち入り禁止. A literal translation of "person" can often sound unnatural to native Japanese speakers if mixed up!
