Hayakawa-guchi Remains

It was part of the structure built by the Hojo clan in preparation for the Battle of Odawara with Toyotomi Hideyoshi at the end of the Sengoku period (1467-1615) and was an important place facing the headquarters of the Toyotomi army. It is thought there was what is called a tiger entrance, an entrance, and an exit, as it has a double structure, a double outer wall, and a moat.
