Kanji for Depression

鬱 (utsu) is the famous monster: twenty-nine strokes, routinely cited as the hardest common kanji in Japanese, and the character for depression — 鬱病 (depressive illness), 憂鬱 (melancholy, gloom). Its original image is vegetation grown so dense nothing moves through it — 鬱蒼 still means “thick with growth” — and the leap from an overgrown thicket to a clouded mind needed no explanation.

Japanese realities around it are worth knowing: the character is so complex that even natives often write うつ in kana, and 鬱 became a minor internet celebrity precisely for its difficulty. The medical vocabulary uses it soberly: 鬱状態, a depressive state; 躁鬱, bipolar (mania and depression).

Nearby sit 憂 (grief, anxiety — the “melancholy” of 憂鬱) and 陰 (shadow, the yin of yin-yang) — softer characters for lower registers of the same weather.
