The Naidaijin (内大臣, Naidaijin; also pronounced uchi no otodo), literally meaning "Inner Minister", was an ancient office in the Japanese Imperial Court. Its role, rank and authority varied throughout the pre-Meiji period of Japanese history, but in general remained as a significant post under the Taihō Code.
