The channels of development and routes of knowledge transfer in Ryukyu-di / By Itzik Cohen

The channels of development and the routes of knowledge transfer in Ryukyu-di, the precursor to karate, provide a fascinating insight into the evolution of Okinawan martial arts and the broader cultural context in which they emerged. The Ryukyu Kingdom, positioned as a central trading hub in East Asia, maintained extensive relationships with a variety of countries and kingdoms, including China, Japan, Korea, Southeast Asia, and beyond. This international engagement exposed the Ryukyuan security teams and guards to diverse sources of knowledge, techniques, and philosophies.

In addition to its rich cultural synthesis, the practice of Ryukyu-di, the ancestor of karate, was shaped by the diverse and demanding contexts in which it was employed, particularly in the realm of security missions. These missions required security staff to operate in a variety of environments and develop a broad spectrum of high-level skills tailored to the unique challenges of each scenario.

One prominent responsibility was guarding the royal household and diplomats, both within the Ryukyu Kingdom and during official travels abroad. Protecting high-ranking individuals in these settings necessitated not only physical prowess but also a keen understanding of protocol, diplomacy, and situational awareness. The role of these guards extended beyond mere combat; they served as protectors, representatives, and, in many cases, deterrents to potential threats.

Securing diplomatic missions was another critical function. The Ryukyu Kingdom's extensive trade and diplomatic relations with nations such as China, Japan, Korea, and various Southeast Asian kingdoms meant that its envoys were often exposed to risks during their journeys. Guarding such missions required adaptability, as guards needed to be prepared to confront diverse terrain, foreign tactics, and a range of environmental conditions. The same level of vigilance and adaptability applied to merchant missions and the protection of trade ships, which faced threats from piracy, rival states, and treacherous maritime conditions.

These varied responsibilities demanded a level of versatility and sophistication in martial training that went beyond simple combat techniques. Guards needed expertise in close-quarters combat, weaponry, unarmed self-defense, and strategic thinking, as well as the ability to remain discreet and professional in highly sensitive situations. Furthermore, they often operated under conditions that required restraint and the use of non-lethal force, particularly in diplomatic contexts, where maintaining peace and decorum was paramount.

The influence of these real-world demands is reflected in the structure and techniques of Ryukyu-di. Many traditional kata contain movements designed to neutralize threats in confined spaces, such as narrow ship decks or palace corridors, while others emphasize responses to multiple attackers or sudden, unexpected confrontations. The adaptability and pragmatism that characterize Okinawan martial arts are direct results of these historical functions, which required warriors and security staff to be resourceful, disciplined, and attuned to the nuances of their environment A closer study of this historical reality is clearly reflected in the approach and techniques embedded within ancient kata(s).

By understanding the multifaceted role of security missions in the development of Ryukyu-di, we gain deeper insight into the martial art’s practical origins and the remarkable skill set cultivated by its practitioners. These historical contexts not only highlight the complexity and richness of Okinawan martial traditions but also underscore their enduring relevance as systems of both close-combat or self-defense and cultural heritage.

A closer examination of Ryukyuan culture underscores the openness and pragmatic adaptability of its people. The Ryukyuan approach to knowledge was not one of passive adoption but active integration, synthesizing foreign elements with native practices to suit their specific needs and worldview. This adaptive process can be traced through both historical records and the study of ancient kata (forms or patterns in martial arts), which serve as living repositories of technique and philosophy.

From this analysis, it is possible to identify key influences on Okinawan martial arts. For instance:
  1. Chinese Influences: These were particularly significant and multifaceted. Contributions from Fujian Province, South China, and even the capital, Beijing, are evident. Fujian, known for its Southern Shaolin traditions and practical close-range combat techniques, provided a technical and philosophical foundation for early Okinawan martial arts. The exposure to Beijing’s martial arts and broader Chinese cultural practices during official missions likely introduced further layers of complexity and refinement.
  2. Japanese Influences: Starting in the early 17th century, Japanese cultural and martial elements began to permeate Okinawan practices. This influence grew steadily stronger over time, particularly following the Satsuma invasion of 1609, which imposed a feudal relationship on the Ryukyu Kingdom. Samurai practices and philosophies inevitably intersected with local methods, leading to some degree of hybridization.
  3. Siamese Influences: Though less widely discussed, influences from Siam (modern-day Thailand) during the 12th to 14th centuries also appear to have played a role. Given the Ryukyu Kingdom’s trading relationships with Southeast Asia, it is plausible that Siamese combat techniques or cultural elements were integrated into Okinawan fighting traditions.

Despite these diverse influences, Okinawan martial arts maintained a distinct identity. The unique geopolitical realities and cultural needs of Okinawa fostered a martial tradition with its own backbone—one that incorporated external knowledge while adapting it to fit the Okinawan environment, social structure, and perception of combat.

This adaptive phenomenon is often encapsulated by the Okinawan concept of " Champulu\Champuru" (a term meaning “mixed” or “blended”), which reflects the ability to integrate foreign elements seamlessly into local culture while maintaining a unique identity. This is not a phenomenon isolated to karate but it is a hallmark of Okinawan culture more broadly. It manifests across various domains, including:
  • Cuisine: The blending of Chinese, Japanese, and Southeast Asian flavors with native ingredients.
  • Music and Dance: Traditional Okinawan music incorporates both local and foreign musical styles, creating distinctive rhythms and melodies.
  • Literature and Poetry: Okinawan literature often reflects the themes of cultural adaptation and synthesis.
  • Visual Arts and Architecture: A combination of Chinese, Japanese, and native Okinawan styles characterizes the region’s aesthetic expressions.
  • Philosophy: Okinawan thought often emphasizes harmony, flexibility, and practicality, reflecting its synthesis of external and internal influences. A combination of hierarchical order along with a friendly and open atmosphere with giving, support, warmth and a developed social life.


In martial arts, this cultural phenomenon has led to the creation of karate as a distinctive art form that integrates diverse techniques and philosophies while remaining fundamentally Okinawan in its core essence. This balance of adaptation and preservation has allowed the Okinawan people to maintain a cultural identity that is both inclusive and unique, reflecting the rich interplay of influences that have shaped their history.
