Nine Star Ki blends classical East Asian cosmology with practical guidance. This site shares those ideas clearly and respectfully so you can explore personality, timing, and relationships.
Nine Star Ki draws on the Five Phases (Wood, Fire, Earth, Metal, Water), the Lo Shu nine-palace grid, and the Eight Trigrams of the I Ching. Early scholars watched the sun's shadow with gnomons (gui biao), recorded directions on bamboo slips, and later used the luopan compass. Along the Yellow River they mapped rhythms of Heaven–Earth—foundations that would eventually shape "nine stars."
Through maritime exchange—traders and Kentōshi envoys—Chinese ideas reached Japan. Across the Heian and Edo periods, scholars and onmyōji adapted them to local life and aesthetics. Chinese theory met Japanese practice, and a distinct form of Nine Star Ki took root.
In Japan, Nine Star Ki became a clear, everyday system: a nine-grid chart paired with numbers, colors, elements, and directions. In gardens beneath Mount Fuji, surrounded by pine trees and stone lanterns, people use Nine Star Ki to choose travel directions, explore compatibility, and plan auspicious timing. Today, digital tools keep the tradition alive while making it easy to use.

How does the nine-number cycle work? Numbers 1–9 rotate in a fixed pattern, each linked to a phase (element) and common tendencies.

How do different schools approach Nine Star Ki? Schools vary slightly, but the aim is the same: combine number, element, direction, and season to read personal rhythm over time.
