Today is Battle of Okehazama Day! Here is something different. An arial photo of Fort Zenshoji. On the right, you can see where the moat was. Nobunaga built Fort Zenshoji in 1559 and Sakuma Nobumori was in change of the fort. It was massive too. The fort measured 768 by 118 feet in length. After the Battle of Okehazama, Nobunaga ordered Nobumori to be in charge of Narumi Castle.
