Overview of Fukuoka Castle

Fukuoka Castle is a castle ruin located in Chuo-ku, Fukuoka City, Fukuoka Prefecture, built in the early Edo period. Kuroda Nagamasa, the feudal lord of Chikuzen Province (present-day Fukuoka Prefecture), spent seven years from 1601 to construct the castle. Also known as “Maizuru Castle,” it is situated in the center of Fukuoka city. The castle grounds were once vast, surrounded by moats and stone walls. However, the castle keep no longer exists today, with the main citadel, turrets, and stone walls conveying remnants of its former glory.

Historically, Kuroda Nagamasa became the lord of 520,000 koku of Chikuzen Province through his achievements in the Battle of Sekigahara. The Kuroda family abandoned their previous base at Najima Castle and built the new Fukuoka Castle. The castle’s design is attributed to Nagamasa’s father, Kuroda Yoshitaka (Josui), a renowned military strategist, and incorporated the latest castle construction techniques of the time.

Fukuoka Castle is a hilltop castle (hirayama-jiro), built in the area of present-day Maizuru Park. The castle was of enormous scale, with the san-no-maru (third bailey), ni-no-maru (second bailey), and hon-maru (main bailey), as well as various turrets and gates of different sizes. The total length of stone walls extended approximately 6 kilometers. It once had a significant influence on the urban development of Fukuoka as a castle town.

As an Edo-period castle, it was an unusually large hilltop castle with a total area of approximately 470,000 square meters. The castle compound consisted of the hon-maru at the center, surrounded by the ni-no-maru and san-no-maru, with turrets of various sizes dotting the perimeter. The “Tamon Turret” in particular is an existing Important Cultural Property and the castle’s symbolic structure. Moats also encircled the castle, demonstrating excellent defensive design.

Due to its historical and cultural value, it has been designated as a “Fukuoka Prefectural Designated Historic Site.” Active preservation efforts are also underway, with ongoing research and surveys of the castle’s ruins and historical materials. In 2014, restoration work on Fukuoka Castle’s main gate ruins and stone walls was carried out, advancing the reconstruction of the historical landscape. The surviving turrets and stone walls are important remains that convey the castle’s grandeur to the present day.

History of Fukuoka Castle

Here we accurately explain the major events in Fukuoka Castle’s history, organized by topic.

　1. Background of Construction and the Kuroda Clan’s Arrival (1601-1607)

Construction of Fukuoka Castle began in 1601 by Kuroda Nagamasa. Having gained lordship of 520,000 koku of Chikuzen Province through his achievements at the Battle of Sekigahara, Nagamasa decided to build a new castle as his base. The Kuroda family had previously been based at Najima Castle, but by building a new castle city in Fukuoka, they aimed to strengthen their domain management and establish a political and economic center. The castle’s design involved Nagamasa’s father, Kuroda Yoshitaka (Josui), and incorporated the latest castle construction techniques. The castle was completed in 1607, after which the Kuroda clan governed from Fukuoka Castle as their headquarters.

　2. Fukuoka Castle During the Edo Period (1607-1868)

Throughout the Edo period, Fukuoka Castle served as the residence of the Kuroda clan. The castle played an important role as the political and military center of the Fukuoka domain.
