Okayama Signaling Hill
岡山烽火場 Okayama noroshi-ba
To the northeast of the town, this was from where the flare was fired that signaled that the Western Alliance needed reinforcements. The signal sent a message to Tokugawa that enabled him to move his camp closer to the battlefield, boosting troop morale among the Eastern Alliance forces. Like Ishida's Encampment, this can easily be seen from most of the town.
