 The "Nihon Shoki" mentions "Ne-no-kuni" in passing when describing an episode where Susanoo was banished from Takama-ga-hara for various evil acts he committed, and went to a place called "(Soko-tsu-)Ne-no-kuni".According to the "Kojiki" when Ōkuninushi visited Ne-no-kuni and insulted Susanoo he was submitted to overcome three ordeals, one being described to sleep in a house infested with snakes, centipedes and wasps.This is sometimes taken as another hint that Ne-no-kuni is a subterranean realm.
