Kūdō (空道) (formerly known as Daido Juku) is a Japanese hybrid martial art. It is a full-contact combat sport that aims to achieve safety, aggression and practicality, a style of mixed martial arts practised with headgear and gloves. It features stand-up striking, with throwing and grappling techniques being also allowed in the competition, including restraint, locks and chokeholds.

Kūdō is a form of budō (modern martial arts) that originated in the Daido Juku school, an organization founded by Azuma Takashi in 1981. The relationship between the Daido Juku school and kudo is similar to that between the kodokan school and judo.
