These are the remains of work sites where stone for the walls of Edo Castle was cut and shaped. In the mountains, the scatter of stones with yakuana, the holes cut to split them, shows where each site was. The Kanpakuzawa group in Hayakawa spreads about 170 m north to south and 1,300 m east to west; 254,127 m² is a national historic site.

Ninomiya Sontoku was born in this house in Kayama in 1787. When he was 16 the land and house were sold, and the house was moved repeatedly before being rebuilt on the site of his birth in 1960. Most of the original timber remains in its beam frame, and it is thought to date from the mid-18th century.

This channel drew water from the Hayakawa near Hakone-Itabashi, ran through the castle town, and left the town at the Edoguchi gate in Hamacho. It is known to have existed by the end of the Sengoku period. It still flows, and the water it takes in runs into the moat of Odawara Castle.
