Rikud

Rikud is a traditional Japanese martial art that focuses on the principles of *rikugun* (力均, "balance of strength") and fluid, efficient movement. Often associated with the *Ninjutsu* (忍術) or ninja arts, Rikud emphasizes adaptability, deception, and the use of natural energy (*ki*) to overcome physical limitations. While not as widely documented as other martial disciplines, its techniques are believed to have been developed by samurai and ninja for both combat and survival in unpredictable environments.

The core philosophy of Rikud revolves around the idea that strength should be directed with minimal wasted motion, allowing practitioners to conserve energy while maximizing impact. Movements are typically circular, spiral, or wave-like, mirroring the flow of nature. This approach is reflected in its training methods, which often incorporate bodyweight exercises, meditation, and the study of animal movement for fluidity.

Rikud is sometimes categorized under *taijutsu* (体術), the unarmed combat aspect of ninjutsu, though it distinguishes itself by its emphasis on energy manipulation rather than brute force. Historical records suggest that ninja and samurai may have used Rikud-inspired techniques to evade capture, disarm opponents, or escape confined spaces. Modern practitioners often blend Rikud with other martial arts, such as aikido or judo, to refine their understanding of leverage and balance.

While Rikud lacks a centralized governing body, its teachings are passed down through private dojos and lineage-based schools. Some practitioners view it as a complementary discipline to traditional martial arts, offering insights into body mechanics and mental focus. Due to its niche nature, detailed historical records are scarce, and much of its knowledge remains anecdotal or preserved in obscure texts. Today, Rikud continues to be studied by martial artists, historians, and enthusiasts interested in Japan’s lesser-known combat traditions.
