ryus

Ryus, also known as *ryū* (龍, "dragon") in Japanese, are a category of traditional Japanese martial arts characterized by their fluid, serpentine movements and emphasis on fluidity, balance, and internal power. These arts are often associated with the mythical dragon, symbolizing strength, flexibility, and adaptability. Ryus are distinct from other Japanese martial arts like karate or judo, as they prioritize continuous, flowing motions rather than discrete strikes or throws.

The origins of ryus can be traced back to ancient Japanese martial traditions, with some schools claiming lineage from legendary warriors or esoteric teachings. Over time, ryus evolved into various styles, each with unique techniques and philosophies. Notable ryu include the *Katori Shinto-ryū*, one of the oldest surviving martial arts schools, and the *Tenshin Shoden Katori Shinto-ryū*, which incorporates swordsmanship, archery, and hand-to-hand combat. Other well-known ryus include *Yagyū Shinkage-ryū* and *Takagi Yoshin-ryū*, both renowned for their swordsmanship and strategic depth.

Ryus often emphasize the concept of *ki* (気), or life energy, and techniques such as *jujutsu* (flexible technique) and *taijutsu* (body techniques). Training typically involves forms (*kata*), sparring (*kumite*), and weapons practice (*buki-waza*), including swords, spears, and staffs. Many ryus also integrate meditation and spiritual disciplines to cultivate mental discipline and internal strength.

While ryus were historically preserved by private dojos and passed down through families, they have gained broader recognition in modern times. Today, some ryus are practiced as standalone martial arts, while others are studied as part of broader *budo* (Japanese martial ways) traditions. Their influence extends beyond Japan, inspiring modern hybrid martial arts and fitness disciplines that value fluid movement and adaptability.
