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.
During the reign of his son, under a regent, the borders were pushed further north and west, provoking reactions from the Tibetans and Chinese as well as the British East India Company, the power to the south.
