How to say "reluctantly" in Japanese

• 渋々しぶしぶCommon
  adverb (with と)The everyday choice for acting reluctantly: the person goes along, but the reluctance shows in their manner. Typical of agreeing to a request or attending something one would rather skip.
  私は、しぶしぶ彼かれの言いうことを聞きいてやった。↗

  I listened to him reluctantly.
• いやいやJLPT N1approx.
  adverbReluctance with the dislike close to the surface: the person complies while, in effect, saying no. Less common than 渋々, and normally written in kana alone.
  その命令めいれいに嫌々いやいや従したがう兵へいもいた。↗

  Some soldiers were reluctant to obey the commands.
• 不承不承ふしょうぶしょう
  adverb, no-adjectiveGrudging consent: agreeing while withholding real approval, so the reluctance reads as disapproval held in check. A four-character idiom whose closest English rendering is often 'grudgingly' rather than plain reluctance.
• いやいやながら
  adverbDoing something while still feeling like saying no — compliance under protest. Essentially the fuller form of いやいや, it stresses yielding despite one's unwillingness, as when taking on a chore one dislikes.
• 仕方なしにしかたなしに
  adverbReally 'helplessly': the person acts because there is no other way, so the feeling is resignation rather than dislike. A marginal match for 'reluctantly' — choose it when having no choice is the point.

Use 渋々 as the default for everyday reluctance; 「いやいや」 and 「いやいやながら」 stress going along while protesting, 不承不承 stresses grudging consent, and 「仕方なしに」 is really resignation at having no choice.
