Using 'cave' in expressions like 'man cave' or 'cave in'.
For 'man cave', Japanese often borrows the English phrase (マンケイブ) or describes it as 男性の隠れ家 (だんせいのかくれが, a man's hideaway). For 'cave in' (collapse), use 陥没する (かんぼつする) or 落ち込む (おちこむ) for emotional collapse.

洞窟 (どうくつ) is the most general and common word for 'cave'. 洞穴 (ほらあな) often implies a smaller, more primitive hollow or den. In many contexts they are interchangeable, but 洞窟 is safer for learners.
The English phrasal verb 'cave in' (collapse) is not directly translated with 洞窟. Use 陥没する (かんぼつする) for physical collapse or 折れる (おれる) for giving in to pressure.
