Présentation
Overview
Tateyama Castle was a hilltop castle (hirayama-jiro) in Tateyama, Tateyama City, Chiba Prefecture, and served as the final stronghold of the Satomi clan, the sengoku daimyo who ruled the southern Bōsō Peninsula. Built on an isolated hill roughly 65.7 meters in elevation, it used steep natural cliffs on its eastern and northern sides together with artificial moats for defense. It is protected as the Tateyama City Designated Historic Site "Tateyama Castle Ruins."
Construction and the Satomi Relocation
The castle is said to have been built in 1580 (Tenshō 8) by Satomi Yoshiyori. Subsequently, between the sixth and eleventh months of 1591 (Tenshō 19), Satomi Yoshiyasu relocated his base here from Okamoto Castle, after which Tateyama Castle served as the Satomi clan's main stronghold and the surrounding castle town was developed. The formation of this castle town laid the foundation for the present-day urban center of Tateyama City.
Structure
Built on an isolated hill roughly 65.7 meters in elevation, the castle used steep natural cliffs on its eastern and northern sides for defense, with artificial moats constructed from the east through the north. The layout followed a linear-bailey (renkaku-shiki) design with baileys, dry moats, and moats including water-filled sections; some researchers have suggested the castle may have incorporated a harbor.
Abandonment and Aftermath
In 1614 (Keichō 19), the tenth Satomi lord, Tadayoshi, was implicated in the Ōkubo Nagayasu affair and stripped of his domain, being exiled to Hōki Province (present-day Tottori Prefecture); the Tateyama domain was dissolved and the castle demolished. Even when Inaba Masaaki became lord of Tateyama domain in 1781, the castle was not rebuilt, and only a residence (jin'ya) was established at its foot. During World War II, an anti-aircraft position was installed on the castle hill, and approximately 7 meters were cut from the summit, significantly damaging the remains.
Present State and Access
Excavations conducted between 1978 and 1980 confirmed the remains of a palace building and the Kashima moat. In 1982, a mock tenshu was built on the summit and opened as an annex of the Tateyama City Museum (the Hakkenden Museum), and the castle site is now maintained and open to the public as Shiroyama Park. About a 5-minute walk or bus ride from Tateyama Station on the JR Uchibō Line.
