Five centuries later, Japan's own Kojiki and Nihon-shoki chronicles describe the creation of the imperial dynasty in the year 660 b.c. : the first emperor, Jimmu ( Divine Warrior ) great grandson of the Sun Goddess's grandson embarked on an expedition of conquest from Kyushu along the Inland Sea coast to the Yamato plain of the Kinki region (near modern-day Nara).
The first emperor was named Jimmu, and was the great grandson of the Sun Goddess.
The imperial dynasty was actually created in 700 B.C, long after the first emperor, Jimmu.
