How to say "easily" in Japanese

• なかなかJLPT N4approx.Common
  adverb, na-adjectiveChiefly an intensifier meaning 'very' or 'considerably'; its 'easily' sense surfaces mostly in negative patterns such as 'not easily done', so it is seldom the straightforward word for plain 'easily'.
  あいつは、なかなかいい奴やつだぜ！↗

  He is a good joker.
• あっさりJLPT N1approx.Common
  adverb (with と), suru verbAn onomatopoeic adverb with a light, unceremonious feel: doing something readily, without fuss or deliberation, as in refusing flatly. Not the neutral word for effort-free 'easily'.
  彼かれはあっさり罪つみを白状はくじょうした。↗

  He confessed his crime frankly.
• 難なくなんなくCommon

  彼かれはその手品てじなを難なん無なくやって見みせた。↗

  He performed the trick with ease.
• 楽々らくらくCommon
  adverb (with と)Covers 'easily' with a nuance of comfort: doing or achieving something with ease, without strain or effort. The image is of a task handled comfortably rather than barely managed.
  ぼくは手てが足あしの指ゆびに楽々らくらくとどくよ。↗

  I can easily touch my toes.
• 優にゆうにCommon
  adverbRestricted to 'easily' in the sense of reaching or exceeding a level or amount, with overtones of 'amply' or 'fully'. Not a general adverb for doing things easily.
  ここから郵便局ゆうびんきょくまではゆうに５キロあります。↗

  The post office is a good five kilometers away from here.

Choose 「難なく」 for plain 'without difficulty', 楽々 for comfortable ease, 「あっさり」 for doing something lightly or without fuss, 「優に」 for easily reaching or exceeding a level, and 「なかなか」 mainly for 'quite' or 'not easily'.
