Relationship with “Kojiki
I would like to consider the beginning of the Japanese wedding ceremony from all angles, without deciding where it began.
The story of Ijanaki Ijanami as the first male and female deity to give birth to the nation is often discussed.
This is already mentioned in the preface before entering the main text.
Yin and Yang opened up, and the two deities, male and female, became the creators of all things.”
This is supposed to be a married couple.
