Fukuoka Castle was built on the land that was awarded to the Kuroda clan (黒田氏) by none other than Tokugawa Ieyasu (徳川家康), one of the three unifiers of Japan. This award was for the contribution of the Kuroda clan as they sided with the Tokugawa clan (徳川氏) in the famed Battle of Sekigahara (関ヶ原の戦い) to defeat the enemies and even killed a famed general known as Shima Sakon (島左近). For reference, the land at that time was called Chikuzen (筑前) before it was integrated into the present Fukuoka province.
The lord of the Kuroda clan, Kuroda Nagamasa (黒田長政) commenced the construction of Fukuoka castle in AD 1601 as a stronghold and administrative centre. Overseeing the construction at that time was a samurai cum mason known as Noguchi Kazunari (野口一成). He was an expert in utilising stones to construct the walls of the castles; gathering them from various sources such as the clan’s former Najima castle (名島城) and the walls that were used against the Mongol invasions centuries ago.
Eventually the impressive castle was completed in AD 1607; in which another warlord known as Kato Kiyomasa (加藤清正) applauded its architecture and even nicknamed it ‘the Stone Castle (石城/seki-jo)’. On top of that, Noguchi Kazunari was recognised for his impressive work and was eventually sent to work on the Edo Castle (江戸城) as well.
While the castle remained a ruling base for the Kuroda clan, it was unfortunately decommissioned in AD 1871 during the Meiji period (明治時代) when the newly established government decided to abolish the feudal system. Today, only ruins of the castle remain as vestiges of the castle’s former glory.
