Demolition work on existing buildings has been underway since October of 2022. 


The plan focuses on three pillars: (1) infrastructure development towards realizing the Shinjuku Grand Terminal, (2) introducing urban functions to enhance international competitiveness, and (3) strengthening disaster prevention capabilities and reducing environmental impact.

The objectives include improving the connectivity between the station and the surrounding areas, promoting business exchanges, and enhancing disaster resilience. 


The project site is within the designated emergency redevelopment area under the Urban Regeneration Special Measures Act, with a land area of about 8,060 square meters.  


A mixed-use building with 48 above-ground floors and 5 below-ground floors will be developed, with a total floor area of approximately 251,000 square meters.  


From the basement 2nd floor to the 10th floor above ground, the new building will house the largest retail facility in the Shinjuku area, while the 12th and 13th floors will serve as an innovation hub, and the 14th to 46th floors will be designated for office space.
