How to say "Casual" in Japanese

When translating "casual" into Japanese, you must choose carefully between 何気ない and 無造作. In Japanese, 何気ない (なにげない (nanigenai)) is typically associated with "casual, unintentional, nonchalant, thoughtless" (Syllabus Level: N2) and represents 意図せずに自然にそうなる様子や、特別な意図がないことを表します。Often describes something done without particular intention or a casual, natural manner.. On the other hand, 無造作 (むぞうさ (muzōsa)) maps to "casual, unconcerned, simple, artless" (Syllabus Level: N2) and represents Describes an action or manner that is done without much thought, effort, or careful planning. It can imply naturalness or simplicity, but sometimes also carelessness. Often used adverbially. A literal translation of "casual" can often sound unnatural to native Japanese speakers if mixed up!
