How to say "Reason" in Japanese

When translating "reason" into Japanese, you must choose carefully between 理由 and わけ. In Japanese, 理由 (りゆう (riyū)) is typically associated with "reason, motive" (Syllabus Level: N4) and represents A noun referring to the cause or explanation for something. Often used with なぜ. On the other hand, わけ (わけ (wake)) maps to "reason, circumstances, meaning" (Syllabus Level: N3) and represents A versatile word implying 'reason', 'circumstance', or 'natural conclusion'. Often used in grammatical patterns like 〜わけだ. A literal translation of "reason" can often sound unnatural to native Japanese speakers if mixed up!
