How to say "vigorous" in Japanese

Choosing the right word
  • 健やかすこやかJLPT N1approx.Common
    na-adjective, nounCovers 'vigorous' only in the sense of healthy and thriving — vigorous growth or development. The natural word for a child growing up strong and healthy, rather than for energetic action.

    The couple who came on a shrine visit, Kouji Oonishi (40) and his wife Yukie (34) said, "We prayed that our child would grow up healthily."
  • 活発かっぱつJLPT N1approx.Common
    na-adjective, nounMatches 'vigorous' as lively, active movement or behavior — an animated child, a brisk exchange of views. The nuance is constant activity and animation, not physical strength or health.
    私わたしたちはとても活発かっぱつな討論とうろんをした。↗
    We had a very vigorous debate.
  • 旺盛おうせいCommon
    na-adjective, nounDescribes energy or appetite at full strength — vigorous in the sense of abundant and flourishing. Typical of a hearty appetite, strong curiosity, or tireless drive, rather than of movement itself.
    彼かれは知識欲ちしきよくが旺盛おうせいである。↗
    He is in a rage to know.
  • 元気げんきJLPT N5approx.Common
    na-adjective, nounThe word for being lively, full of spirit, and energetic — 'vigorous' in the sense of full of life and good health. The natural choice for a person, especially a child, brimming with energy.
  • 力強いちからづよいJLPT N2approx.Common
    i-adjectiveCovers 'vigorous' when the emphasis is on power and force — a forceful, powerful quality of action or movement. Closer to 'strong' than to 'lively'; not the word for a healthy or energetic person.
    踊り子おどりこ達たちは白しろいドレスを着きてきゃしゃに見みえますが、実際じっさいには彼女かのじょたちは馬うまのように力強ちからづよいのです。↗
    The dancers look delicate in their white dresses, but they are really as strong as horses.

Choose 「健やか」 for healthy thriving, 活発 for lively activity, 旺盛 for abundant drive or appetite, 元気 for being lively and full of spirit, and 「力強い」 when vigorous means powerful or forceful.
