How to say "satisfactory" in Japanese

Choosing the right word
  • ろくなJLPT N1approx.Common
    pre-noun adjectivalRarely the neutral word for 'satisfactory': it usually appears in negative sentences, denying that anything decent or proper is there — no decent explanation, hardly any satisfactory results.
    麻薬まやくに手てを出だすとろくなことはない。↗
    If you mess with drugs, you're asking for trouble.
  • 可かJLPT N3approx.Common
    noun, noun (suffix)Chiefly a grade or mark of approval: 'acceptable' as in a bare pass on a scale, or 'permitted'. As a free-standing way to say 'satisfactory' in ordinary sentences it is marginal.

  • 十分じゅうぶんJLPT N4approx.Common
    na-adjectiveUse this when 'satisfactory' means adequate or good enough — the explanation, time, or amount meets the need. It judges sufficiency rather than praising quality.
    私はこの本ほんを買かうのに十分じゅうぶんなお金かねを持もっている。↗
    I have enough money to buy this book.
  • 好調こうちょうJLPT N1approx.Common
    na-adjective, no-adjectiveCovers 'satisfactory' in the sense of favorable: business, sales, or performance that is going well. It comments on how things are progressing rather than on whether something is merely adequate.
    滑り出すべりだしが好調こうちょうなら事ことは半なかば成就じょうじゅしたのに等ひとしい。↗
    Well begun is half done.
  • 良好りょうこうJLPT N1approx.Common
    na-adjective, noun'Satisfactory' as a positive verdict that a state or result is good: conditions, results, or relations described as fine or favorable. It evaluates the state of things, not sufficiency.
    それに比くらべ最近さいきん彼女かのじょのお天気てんきは良好りょうこう。↗
    In comparison to which she's been in a really good mood recently.

Choose 十分 when 'satisfactory' means adequate or good enough; 好調 and 良好 for favorable results or conditions; 可 for a bare pass or approval; 「ろくな」 mostly appears in negative sentences denying anything decent.
