How to say "cozy" in Japanese

• コージー
  na-adjective, nounA direct borrowing of English 'cozy', used much as the English word is, especially in interior, café and lifestyle descriptions. It is less common than the native options.
• アットホーム
  na-adjective, nounCovers the homey, welcoming side of 'cozy': a place or atmosphere that makes people feel at ease, as if at home. Typical of shops, offices and gatherings rather than physical snugness.
• 居心地の良いいごこちのいい
  expression, i-adjective (よい/いい)Focuses on how comfortable a place is to be in — a room, seat or café where you can relax. The natural choice when 'cozy' means physically snug and comfortable rather than warm-hearted.
• 居心地いいいごこちいい
  i-adjective (よい/いい)The same idea as 居心地の良い in a shorter, more casual shape — いい for 良い, with the の dropped. Pick it when that shorter, more relaxed feel suits your sentence.
  私はこの部屋へやを居心地いごこちよくしよう。↗

  I'll make the room comfortable.
• ほんわか
  adverb (with と), suru verbA colloquial, mimetic word for a soft, gently warm, mellow feeling. It matches 'cozy' only loosely, suiting a relaxed, warm atmosphere rather than the snugness of a room.

Choose 「居心地の良い」 or 「居心地いい」 for a place that feels comfortable to be in, 「アットホーム」 for a welcoming, home-like atmosphere, 「ほんわか」 for gentle warmth and relaxation, and 「コージー」 as the direct loanword in interior or café descriptions.
