What is Nine Star Ki?
A form of divination that looks at good directions and timing through nine stars (from the One White Water Star to the Nine Purple Fire Star), set by the year and month you were born. Sonoda Shinjirō put it together in 1924. This site reads the three books he wrote himself.

Whatever your birth year
This month, 3 directions are best avoided by everyone
- 5Southwest Five Yellow Killing
- DNortheast Dark Sword Killing
- BSoutheast Month Breaker
These three are set regardless of birth year. Your own good directions depend on the stars of the year and month you were born, and differ from person to person.

Your two stars as a pair
We look up two people's birth stars in both directions in the Nine Star generating-and-overcoming table of Kaisei Hōi Meikan. The original says nothing about compatibility between people, so we state clearly that this site has applied a table of directions to two people.

Open the original, and you find three differences
Methods vary between schools and books. Here we show, with page numbers, what the founder's original books teach.
1You use more than the one star of your birth year
「二十歲以上は、年月の本命二星を以て吉方を併用す。」Kaisei Hōi Meikan, original p. 9 (“From age 20, use the two birth stars of year and month together for lucky directions.”)
2The eight directions are not the same width
「四正は各三十度。四隅は各六十度であつて、斯く定めて適用すると凡ての作用がよく符合するのである。」Kaisei Hōi Meikan, original p. 4 (“The four cardinal directions are 30° each and the four corners 60° each; set this way and applied, every effect matches well.”)
3The month and year matter more than “today's lucky direction”
「日よりは月の吉方が貴く、月よりは年の吉方が重且つ大である」Kaisei Hōi Meikan, original p. 10 (“A lucky direction of the month is worth more than one of the day, and a lucky direction of the year is weightier and greater than one of the month.”)
Based on three books the founder wrote himself
Kaisei Hōi Meikan
Eto Kyūsei Urū Kaisetsu
Unsei Hiroku, 1934 edition
All three are public in the National Diet Library Digital Collections, so anyone can check the images of the originals. Where the original sets nothing, we add nothing and show Not in the original. Where we fill in with modern calculation, such as the calendar (dates and times of the solar terms), we say so clearly too.
