How to say "Be" in Japanese

When translating "be" into Japanese, you must choose carefully between 活躍する and 担当する. In Japanese, 活躍する (かつやくする (katsuyaku suru)) is typically associated with "to be active; to play an active part; to flourish" (Syllabus Level: N3) and represents Often used to describe someone performing well or playing a significant role in a specific field, event, or situation.. On the other hand, 担当する (たんとうする (tantō suru)) maps to "to be in charge of; to take responsibility for; to be responsible for" (Syllabus Level: N3) and represents Often used in business or formal settings to indicate being responsible for a specific role, task, or department. It implies taking on a duty or charge.. A literal translation of "be" can often sound unnatural to native Japanese speakers if mixed up!
