In Nihonshoki, Takamimusubi is a god who merely appears in the Arufumi (supplement volumes of explanatory notes in Nihonshoki) Vol. 4 which covers the beginning of heaven and earth, and in Chapter 15 "Kenzo-ki" (Records of Kenzo period), wherein its name appears in an episode of Abe no omi no kotoshiro (a representative of Abe clan in present-day Ueno, Iga City, Mie Prefecture) making a stopover at the islands of Iki and Tsushima when he was dispatched to Mimana (countries in the southern Korean Peninsula).
タカミムスビは、日本書紀では、天地初発条一書第四に「又曰く～」という形式で登場しているに過ぎない神であり、その他では巻十五の顕宗紀において阿閇臣事代が任那に派遣され壱岐及び対馬に立ち寄った際に名前が登場する程度ではある。
