The Full Moon Poem — A Verse Composed at the Pinnacle of Power by the Greatest Authority of the Heian Court
In 1018 (Kannin 2), at the banquet where his third daughter Ishi was installed as the principal consort of Emperor Go-Ichijō, Fujiwara no Michinaga composed: 'This world, I think, / is indeed my world— / the full moon / lacks nothing, / nothing at all.' The poem expressed his satisfaction at having three daughters simultaneously installed as consorts of the emperor and crown prince, making him the supreme power at court as maternal grandfather. The expression 'the full moon lacks nothing' (mochizuki no kakeru) — signifying a complete, perfect hold on power — became the symbol of his dominance. This poem is invariably included in modern high school Japanese history and literature textbooks.
