The Origins and History of Onmyoji

The seeds of Onmyoji were sown in ancient China, nurtured by the philosophical concepts of yin and yang. These opposing yet complementary forces represent the duality inherent in the universe, influencing everything from the seasons to human emotions. The concept of yin and yang found its way to Japan during the Nara period (710-794 AD), where it took root and blossomed into a unique system of divination and spiritual practice.

During the Heian period (794-1185 AD), Onmyoji reached its zenith. The imperial court embraced these practitioners, seeking their guidance on matters ranging from astrological predictions to the construction of palaces. The Onmyoji, with their deep knowledge of yin-yang cosmology, celestial cycles, and the supernatural realm, served as advisors, astrologers, and exorcists, wielding considerable influence over the court.

Their legacy, however, extends far beyond the confines of the imperial palace. Onmyoji practitioners infused their wisdom into various aspects of Japanese culture, from literature and art to daily rituals and folk beliefs. Their influence can still be felt today, as their captivating stories and practices continue to inspire artists, filmmakers, and even modern-day practitioners who strive to keep this ancient tradition alive.

One of the most famous techniques was the six-reed divination method (Rokkaku), where practitioners would manipulate six reeds to reveal auspicious or inauspicious signs.
