How to say "flexible" in Japanese

Choosing the right word
  • 柔軟じゅうなんJLPT N1approx.Common
    na-adjective, nounCovers flexible in the sense of adaptable — flexible thinking, attitudes, or responses — and also physical litheness. Reach for this when flexibility means an ability to bend or adapt rather than mere softness.
    考え方かんがえかたは柔軟じゅうなんでなければならない。↗
    You must be flexible in your thinking.
  • na-adjective, nounA loanword for flexible schedules, working arrangements, and systems that can change, also for physically bendable materials in technical contexts; it overlaps with 柔軟 but sounds more businesslike.
  • しなやかJLPT N1approx.Common
    na-adjectiveFlexible in the physical sense: bending smoothly and springing back, with an elastic, graceful quality. Used of supple bodies, limbs, and movement; it suggests lithe beauty more than adaptability.
  • 柔らかいやわらかいJLPT N4approx.Common
    i-adjectivePrimarily the word for 'soft' — soft pillows, skin, voices. Its 'flexible' sense is secondary and physical, a soft pliability; for adaptable thinking or arrangements it is seldom the word you want.
    私は柔やわらかいベッドで眠ねむるのが好すきです。↗
    I like to sleep on a soft bed.

Use 柔軟 for adaptable thinking or responses, 「フレキシブル」 for flexible schedules and systems, 「しなやか」 for graceful physical suppleness, and 「柔らかい」 mainly when you mean soft rather than flexible.
