noun
first emperor to rule the land (title of Emperor Sujin)
A historical and mythological title from the Kojiki and Nihon Shoki, specifically referring to Emperor Sujin as the first ruler to pacify and govern the realm. Not used in modern Japanese outside of historical or mythological contexts.
『古事記』では、御肇国天皇は崇神天皇の和風諡号とされる。
In the Kojiki, Hatsukunishirasu Sumeramikoto is considered the Japanese-style posthumous name of Emperor Sujin.
The title is composed of 御 (honorific prefix), 肇 (begin, initiate), 国 (land/country), and 天皇 (emperor), literally 'the emperor who first founded the land'. The reading はつくにしらすすめらみこと is an ancient honorific phrase meaning 'the emperor who first ruled the land'. The exact historical derivation is uncertain, but it is firmly associated with Emperor Sujin in early Japanese chronicles.
