How to say "Introduction" in Japanese

When translating "introduction" into Japanese, you must choose carefully between 紹介 and 導入. In Japanese, 紹介 (しょうかい (shōkai)) is typically associated with "introduction" (Syllabus Level: N4) and represents The act of introducing someone or something. Often used with する. On the other hand, 導入 (どうにゅう (dōnyū)) maps to "introduction (of something new), installation, implementation" (Syllabus Level: N3) and represents Used when starting to use or bring in something new. A literal translation of "introduction" can often sound unnatural to native Japanese speakers if mixed up!
