Entrusted with escorting the young son of Matsudaira Hirotada to Sunpu Castle as a hostage to the Imagawa clan, they instead sold the boy to Oda Nobunaga in exchange for a cash payment.

The Toda's home base was Tahara Castle, a fortification perched on a small hill near the root of the Atsumi Peninsula, surrounded by the tidal inlets of Mikawa Bay. The castle's story is inseparable from the feudal power struggles of central Japan, a saga of clans rising and falling with each shift in military fortune.

Matsudaira Hirotada, seeking protection from the Imagawa, agreed to send his young son as a hostage to Sunp...
