Nine Star Ki is Japan's profound system of directional astrology rooted in the nine stars of Chinese cosmology. Enter your birth date and a target date — the system calculates auspicious and inauspicious directions across three celestial boards: Year, Month, and Day.
The I Ching (Zhou Yi) is one of humanity's oldest oracles — a 3,000-year-old system of 64 hexagrams that reveals the nature of any situation. Emperors and sages consulted it for millennia. Now its wisdom is available in precise digital form, faithful to the original classical text.
Both systems are entirely in Japanese — here's a quick guide to get started

The Nine Star Ki system is based on the authoritative text "Introduction to Directional Studies" by Akimitsu Takagi, verified against the original for complete accuracy. The I Ching follows the classical Zhou Yi tradition.
