Odawara Castle (小田原城, Odawara-jō) is a reconstructed Japanese castle in the city of Odawara in Kanagawa Prefecture, Japan. The current donjon (keep) was constructed out of reinforced concrete in 1960 on a stone foundation of the former donjon, torn down from 1870–1872 during the Meiji Period. There has been fortifications at or around the castle's current site since the Kamakura Period (1185–1333). The reconstructed Odawara Castle was listed as one of the 100 Fine Castles of Japan by the Japan Castle Foundation in 2006.
