noun
low profile; humble attitude
Describes a deliberately modest, non-confrontational stance, often in negotiations or public relations. Can be used literally for a low physical posture, but the figurative sense is far more common.

He always interacts with people in a humble, low-key manner.
会社は不祥事を受けて低姿勢に徹した。
The company maintained a thoroughly low profile in the wake of the scandal.
腰が低い is an idiomatic expression for a naturally humble or approachable demeanor, whereas 低姿勢 often implies a calculated or situational low profile.
Compound of 低 (low) and 姿勢 (posture, attitude). The figurative meaning of a humble or non-assertive stance developed naturally from the literal sense of a low physical posture.
