Niiname-sai (Shinagawa Jinja Shrine)

This festival is dedicated to giving thanks for the harvest. The festival was established in 1570, and when in 1600 Tokugawa Ieyasu departed for the frontlines and reigned victorious over the Battle of Sekigahara in 1600, the festival also became dedicated to the victory. People visiting give prayers of thanks by way of offering a mask.
