Welcome to Fukuoka Castle, a place where a feudal lord's stronghold has become one of the city's great open spaces. Its local name is 舞鶴公園, Maizuru Park, and the park is centered on the old main enclosure of the castle, the honmaru. You are in Chuo Ward, in the heart of Fukuoka, about one and a half kilometers west of Tenjin. Walk west from Tenjin Station for around 20 minutes and the sounds of the city start to fade. The park sits just east of Ohori Park, and the two together form a green belt through the middle of the city. The district called Jonai, which is mostly this park, covers about 49.73 hectares, and 39.3 hectares of that is parkland. That is a remarkable amount of open ground this close to downtown. Over the next few stops, we will look at why this spot was chosen for a castle, what remains of the fortress today, the older story hiding beneath it, and how the seasons bring crowds back to its stone walls. First, settle into the idea that you are standing on what was once the command center of a domain.
