Ogawamatobaokajō was the residence of Honda Souzauemon. Nearby was Ogawajō, the residence of the Ishikawa Clan, though I don't know if the sites existed at the same time, although if they did then likely Honda was a retainer of the Ishikawa Clan who controlled Ogawajō and were vassals of the Mikawa Matsudaira Clan.
Matoba refers to an archery range, which is interesting, and "oka" means "hill", although this area is quite flat. "Jō" of course means "castle", at least in the Japanese sense of a general fortification, but it seems that this site was a yakata, or fortified manor house, rather than a castle per se.
