Nine Star Ki (Kyūsei Kigaku) is a core Japanese astrology system blending Chinese Nine Star theory, Five Element philosophy, and the Lo Shu magic square numerology, systematized by Meiji-era scholar Sonoda Shinjiro. Your birth year determines your 'life star' (from 1 Water to 9 Fire), revealing personality traits, compatible relationships, and annual fortune cycles. It remains one of Japan's most widely used divination systems.
