On this site in Kokura, a hub that has prospered along with water transportation, we will create a symbol of Kitakyushu Kokura that will be primed in the long term through a market x town-like guest room. In Japan, since the high-growth period, redevelopment has been progressing, especially in city centers, which are now being built as high-rises through scrap-and-build. This high-rise, profit-driven, packaged redevelopment has resulted in a homogenized city. We propose a sustainable regional redevelopment approach that aims to turn local areas into destinations, and repeatedly expand and renovate them through "self-building," which is the market mindset over the long term. We expect to gradually give the entire area a circulation by inserting guesthouses in vacant houses and storage sheds through the market architecture of Tanga. The goal is to increase the number of long-term fans of the area by holding one-off events to increase opportunities to visit, and eventually to open new stores or move to the area.
