In martial arts, the terms hard and soft technique denote how forcefully a defender martial artist counters the force of an attack in armed and unarmed combat. In the East Asian martial arts, the corresponding hard technique and soft technique terms are 硬 (Japanese: gō, pinyin: yìng) and 柔 (Japanese: jū, pinyin: róu), hence Goju-ryu (hard-soft school), Shorinji Kempo principles of go-ho ("hard method") and ju-ho ("soft method"), Jujutsu ("art of softness") and Judo ("gentle way").

Regardless of origins and styles, "hard and soft" can be seen as simply firm/unyielding in opposition or complementary to pliant/yielding; each has its application and must be used in its own way, and each makes use of specific principles of timing and biomechanics.

In addition to describing a physical technique applied with minimal force, "soft" also sometimes refers to elements of a discipline which are viewed as less purely physical; for example, martial arts that are said to be "internal styles" are sometimes also known as "soft styles", for their focus on mental techniques or spiritual pursuits.
