Hiroshi Kagawa
I-Ching Researcher & Chinese Metaphysics Writer
Japan
Hiroshi Kagawa has researched the I-Ching as a decision-making and divination framework for 25 years, and writes on the wider Chinese metaphysical system it belongs to: the Four Pillars of Destiny, the sexagenary cycle, and the lunisolar calendar and almanac tables that date selection is drawn from. His background in East Asian Philosophy informs his work on hexagram interpretation, day and hour boundary conventions, and dream symbolism in Buddhist and Taoist traditions. He is currently preparing a modern commentary on the I-Ching that ties classical hexagram readings to contemporary decision frameworks.
