How to say "kind-hearted" in Japanese

• 仁慈じんじ
  nounCovers the 'benevolent' side of 'kind-hearted', presenting kindness as a formal virtue rather than everyday warmth. As a less common word, it is seldom what you want in conversation; it really names benevolence or mercy.
• 情の深いじょうのふかい
  expression, i-adjectiveDescribes a person whose compassion runs deep — someone who is kind-hearted, charitable, and moved by others' troubles. Use it when you want to emphasize warm, humane depth of feeling rather than simple niceness.
• ハートフル
  na-adjectiveA loanword covering 'heart-warming' and 'kind-hearted'; it suggests a warm, considerate, feel-good quality. It fits descriptions of warm-hearted attitudes or touching, uplifting works better than plain description of a kind person.
• 心の優しいこころのやさしい
  expression, i-adjectiveThe natural choice for an ordinary kind-hearted person: someone whose heart is gentle and kind. Use it for everyday praise of a person's character, where 'kind' and 'kind-hearted' overlap almost completely.
