Hand mechanism, gripping system, and non-transitory storage medium

A hand mechanism grips an object more favorably, regardless of the attitude and surrounding conditions of the object. When an object is to be gripped by a hand mechanism having three or more finger portions, at least one finger portion among the three or more finger portions functions as a state-altering finger portion for altering the attitude or the position of the object while contacting the object, and at least two finger portions among the finger portions other than the finger portion functioning as the state-altering finger portion function as gripping finger portions for gripping the object in a state where the attitude or the position has been altered by the state-altering finger portion.
