Centered around a soccer stadium, this large-scale mixed-use complex—comprising an arena, offices, retail, and a hotel—is being developed under private-sector leadership. The facility was meticulously designed with the visitor’s experience in mind, featuring open, inviting spaces that integrate seamlessly into everyday life. A looped circulation design encourages movement throughout the site, while environmental considerations reflect a commitment to future generations. This project attempts to pioneer a range of Japan’s first-ever innovations from Nagasaki.
