What is Kishuku Castle? | Historical Heritage Telling the Roots of the Goto Clan
Historical Background of Kishuku Castle
Kishuku Castle is a mountain castle built in 1375 (Eiwa 1) by Ukusato Shikō. Uku Kakuko was a figure who moved from Uku Island (present-day Uku-cho, Sasebo City) to Fukue Island in the Goto Islands, and is considered the ancestor of the Goto clan.
The Uku clan was originally a family descended from the Taira clan, and after the Genpei War, they expanded their power into western Kyushu. The reasons for Uku Kakuko’s relocation to Fukue Island included the political situation at the time and the strategic importance of the Goto Islands as a key point for maritime traffic. Kishuku Castle was built as a base in this new territory.
Characteristics as a Mountain Castle
Kishuku Castle is a typical medieval mountain castle built on the summit of Shirodake Mountain, approximately 220 meters above sea level. Mountain castles have excellent defensive structures, and their high vantage point allows for early detection of approaching enemies.
Structurally, the castle is thought to have consisted of baileys (kuruwa) such as the main bailey, second bailey, and third bailey, with defenses reinforced by stone walls and earthworks. Even today, careful observation of the terrain reveals traces of the castle’s fortifications.
The Historical Place of the Goto Clan
Kishuku Castle served as the Goto clan’s first residence and their base for approximately 200 years. Although the Goto clan later moved their base to Ishida Castle (Fukue Castle), Kishuku Castle, as the birthplace of the Goto clan, still holds special significance in the history of Goto City.
The Goto clan ruled the Goto Islands from the Sengoku period to the Edo period, playing a crucial role as a key point for maritime traffic. Kishuku Castle was the foundation of this power and is an indispensable historical site for understanding Goto City.
