The first two generations were hitorigami while the five that followed came into being as male-female pairs of kami: male deities and sisters that were at the same time married couples.
In total the Kamiyonanayo consist of 12 deities in this chronicle.
[1] In contrast, the chronicle Nihon Shoki, points out that this group was the first to appear after the creation of heaven and earth.
Finally the Nihon Shoki uses a different spelling for the names of all deities.
The last generation formed by Izanagi and Izanami were the couple that would be responsible for the creation of the Japanese archipelago (Kuniumi) and would engender other deities (Kamiumi).
