The site of Tokyo's famed Tsukiji fish market, a vacant plot since it was demolished a few years back, is to be redeveloped into a bustling waterfront district featuring a 50,000-seat stadium and a cluster of high-rise buildings, along with a life sciences hub. Under a master plan released 22 August by a consortium of contractors, nine buildings will be erected, including a 210-meter-tall skyscraper. The 19-hectare plot owned by the Tokyo metropolitan government was turned into a temporary parking lot for the 2020 Summer Olympics. Consortium officials pledged to preserve any buried cultural artefacts and sort out possible soil pollution problems before embarking on the main construction work in fiscal 2028. The master blueprint envisions a large-scale venue for events and exchanges, collaborating with the Tsukiji Outer Market next door to promote culinary culture, and establishing a base for life sciences that will bring together cutting-edge technologies. The motif of a traditional Japanese fan will be evoked in the design of the indoor stadium's roof to embody hopes for harmony, growth and prosperity, officials said.
