Hachioji Castle was located on Mt.  Fukazawa 深沢山 <ref>The modern name of the mountain, Shiroyama, means "castle mountain."</ref> near Kobosatsu Pass 小仏峠, the place where Kôshu Kaidô, a [[highways|highway]] to [[Kai province]] enters the [[Kanto|Kantô Plain]]. It was built by the [[Go-Hojo clan|Hôjôs]] of [[Odawara castle]], the dominant family of the Kantô at that time. It was overwhelmed and destroyed during [[Toyotomi Hideyoshi|Hideyoshi's]] [[siege of Odawara]].

The castle was built as an outpost of Odawara Castle by Hôjô Ujiteru, the younger brother of [[Hojo Ujimasa|Hôjô Ujimasa]]. In [[1569]] [[Takeda Shingen]] of Kai had passed through the Kôshû highway to attack [[Takiyama castle]] 滝山城, located near where the Akikawa River flows into the Tama River. According to some sources, Hachioji Castle was begun soon after, but perhaps only some basic fortifications were made, as other sources give various dates in the 1580s.

In 1580 the Hôjôs visited [[Oda Nobunaga]] in [[Azuchi castle]], and it is believed that this visit influenced the building of Hachiôji castle and the main residential building was made as splendid as possible. Some pieces of Chinese pottery and even some Venitian lace glass, unique from that period in Japan, have been found on the site.

In [[1590]] Hideyoshi launched his invasion of the Kantô and besieged Odawara Castle. He did not attack Odawara itself, but rather the other Hôjô castles, one after another.
