He belongs to the seventh generation of the heavenly deities; but of the five generations of earthly deities he is the first. He was the oldest and the only fruitful son of his parents. His children are the Japanese, born in a time when they themselves were half-deities, and lived very much longer than the present human beings. In a direct line of succession, the emperors follow him; therefore his name, which signifies "the great god of the imperial generation." He himself reigned a quarter of a million of years. During this time he performed the most stupendous miracles, and proved himself the only and true god. The province of Isje is his residence, and there stands the most renowned of his triumphs. The great feast which is celebrated in his honor is called Matsuri. His successor in the kingdom was his son Osi-Mo-Nino-Mikol.
