Common expressions

Cultural note

The battle is the best-known single day in Japanese history, retold constantly in novels, films, and taiga dramas. Because everyone knows how much rode on it, the name works in ordinary conversation as shorthand for a decisive moment, much as "Waterloo" does in English — though Sekigahara names the contest itself rather than a defeat.
