Translation

親密な / 個人的な / 私的な

Meaning

Intimate means very close, private, and personal. It can describe relationships, conversations, details, settings, or physical closeness. The trap is that intimate can imply romance or sexuality, so it may be too strong for ordinary friendship.

Examples

• 彼らは親密な会話をしていました。
  They were having an intimate conversation.
• そのレストランは小さくて親密な雰囲気です。
  The restaurant has a small, intimate atmosphere.
