Nuance Contrast & Translation Difference
When translating "reason" into Japanese, you must choose carefully between 訳 and 理性.
In Japanese, 訳 (わけ (wake)) is typically associated with "reason; cause; meaning; circumstances; result" (Syllabus Level: N3) and represents Explains the reason or circumstances behind something. Often used in phrases like 「〜わけだ」.
On the other hand, 理性 (りせい (risei)) maps to "reason; intellect; self-control; sanity; rational mind" (Syllabus Level: N3) and represents Refers to reason, intellect, self-control, sanity, or the rational mind that suppresses emotional impulses to make logical and moral decisions. Often used as 理性を失う. A literal translation of "reason" can often sound unnatural to native Japanese speakers if mixed up!
