 Shiodome Station was officially closed in October 1987, shortly following the privatization of Japan National Railways.The abandoned 22 hectare (54.36 acre) facility, one of the largest open plots of land in central Tokyo, was transferred to the JNR Settlement Corporation in 1988 and earmarked for sale in order to discharge remaining JNR liabilities.The Japanese government and Tokyo Metropolitan Government held various review sessions between 1984 and 1995 before settling on a redevelopment plan.
