The U.S. military completed the return of the Negishi Housing Area in Yokohama to Japanese control on June 30, 2026 [1].

This handover marks the resolution of a decades-long land dispute and provides the city of Yokohama with a significant tract of land for urban redevelopment. The return of the site is a key step in reducing the footprint of U.S. military installations within densely populated Japanese urban centers.

The returned area covers approximately 43 hectares [2]. The U.S. military originally took control of the district in 1947 [3]. This means the land remained under U.S. jurisdiction for 79 years [3].

The process of returning the land was not immediate. The governments of Japan and the U.S. reached a formal agreement to return the site in 2004 [3]. Following that agreement, the two nations worked through the Joint Committee to finalize the handover timeline.

"The return date was decided for June 30," a Yokohama city official said [1].

The Ministry of Defense provided further confirmation regarding the scope of the agreement. The ministry said the Joint Committee agreed to return all areas of the district by June 30 [4].

The transition follows years of coordination between local officials and the defense ministry to ensure the site was ready for transfer. The return of the entire district allows Yokohama to move forward with plans for the land, which may include university research facilities and public parks, without the restrictions of military occupation.

“The return of the site is a key step in reducing the footprint of U.S. military installations within densely populated Japanese urban centers.”

The return of the Negishi Housing Area is a tangible outcome of the 2004 bilateral agreement, reflecting a long-term strategy to consolidate U.S. forces in Japan. By regaining 43 hectares of prime real estate in Yokohama, the local government can now shift from military coexistence to urban revitalization, potentially boosting the local economy through the development of academic and recreational infrastructure.
