History

The Hara Clan, chief retainer of the Chiba clan, had one of their leading vassals Takagi Taneyoshi build Kogane Castle in 1537. The castle was further fortified around 1560 against advances by Uesugi Kenshin. In February of 1566 the castle outlasted a siege by the Uesugi. In 1590 the castle fell to Asano Nagamasa in the Siege of Odawara. The castle was commanded by the Takagi for 3 generations and 53 years. After the Siege of Odawara, one of Ieyasu's sons Takeda Nobuyoshi commanded the castle until it was abandoned in 1593.

Field Notes

The original castle was actually quite vast and with a prosperous castle town. Unfortunately, most of the castle has been developed over but a significant number of building foundations and artifacts have been discovered over the years. What you see today is a small part that remained atop one of the hills. There is also another small park nearby with one of the gates. Unebori and Shojibori style moats and trenches typical of Hojo construction have been uncovered at the castle but are now mostly buried. I thought there was more to see of the unebori which was the main reason I went but all you can see today is in the pictures here.
