In Takanawa, Minato Ward, Tokyo — right next to Sengakuji Station where the Toei Asakusa Line and Keikyu Main Line intersect — construction of a mixed-use complex standing approximately 145 meters tall with 30 above-ground floors is now in full swing. The "Sengakuji Station District Type 2 Urban Redevelopment Project" is a publicly led redevelopment initiative executed by the Tokyo Metropolitan Government that integrates station improvements with surrounding area development, with completion targeted for fiscal year 2031. Now that the grand opening of the adjacent Takanawa Gateway City was completed in March 2025, the Sengakuji Station area has become the epicenter of the next major transformation in southern Minato Ward.
What Is the Sengakuji Station District Type 2 Urban Redevelopment Project?
The Sengakuji Station District Type 2 Urban Redevelopment Project is a publicly led redevelopment executed by the Tokyo Metropolitan Government. While standard "Type 1 Urban Redevelopment Projects" use a rights conversion method, "Type 2" projects employ an administrative disposition method. Rather than remaining within the project site, existing rights holders receive compensation and relocate outside the project area. This approach is commonly applied when highly public-interest urban infrastructure improvements — such as station upgrades and district heating/cooling systems — are required, and the Sengakuji Station district is a textbook example.
The Tokyo Metropolitan Government's Second Urban Development Office serves as the project administrator, with Tokyu Land Corporation and Keikyu Corporation designated as specified builders in June 2021. Kajima Corporation handles design and construction, and construction of the specified facility building officially began on November 1, 2024. The project spans a long-term timeline from fiscal year 2018 to fiscal year 2032, reflecting a strong commitment to sustainable urban development.
Project Scale and Timeline
A summary of the building's key specifications makes the sheer scale of the project clear.
- Location: Takanawa 2-chome, Minato Ward, Tokyo
- Structure: 30 above-ground floors, 3 basement levels
- Maximum height: Approximately 145 meters
- Site area: Approximately 8,490 square meters
- Total floor area: Approximately 112,300 square meters
- Uses: Residential units (385 units), offices, retail, childcare support facilities
- Design and construction: Kajima Corporation
- Construction start: November 1, 2024
- Scheduled completion: Fiscal year 2031 (late March 2032)
With a total floor area of approximately 112,300 square meters, this ranks among the largest mixed-use developments in Minato Ward. The vertical mixed-use configuration — retail on lower floors, offices on mid-level floors, and residential condominiums (385 units for sale) on upper floors — achieves an integration of work, living, and commerce that will keep the neighborhood vibrant around the clock. The inclusion of childcare support facilities aligns with Tokyo's child-rearing policies and is noteworthy from the perspective of creating a family-friendly environment.
The environmentally conscious design is also a distinguishing feature. Exterior louvers installed on the building's facade are adjusted in orientation and density according to the varying solar radiation levels across different areas of the facade, reducing solar heat gain inside the building. This design, which balances energy efficiency with aesthetic quality, reflects a commitment to meeting modern environmental standards.

Synergies with Takanawa Gateway City and Integrated District Development
Any discussion of the Sengakuji Station district redevelopment must address its relationship with the adjacent "TAKANAWA GATEWAY CITY." Takanawa Gateway City is a redevelopment project of overwhelming scale, boasting a total site area of approximately 74,000 square meters and a total floor area of approximately 845,000 square meters, with its grand opening completed on March 27, 2025.
Its core facility, "THE LINKPILLAR 1" (North and South), opened on March 27, 2025. The upcoming "THE LINKPILLAR 2" is a supertall building with 31 above-ground floors and a height of approximately 167 meters, housing offices, commercial facilities, clinics, fitness centers, and a district heating/cooling energy center, with an opening scheduled for March 28, 2026.
Upon completion, the Sengakuji Station district redevelopment building is planned to connect to JR Takanawa Gateway Station via an elevated pedestrian deck running through THE LINKPILLAR. This will dramatically improve access from Sengakuji Station on the Toei Asakusa Line and Keikyu Main Line to Shinagawa Station on the JR Yamanote Line, Keihin-Tohoku Line, and Tokaido Shinkansen. The vision is one where Sengakuji Station transforms qualitatively from a mere "transfer station" into a "gateway to the city."
Furthermore, in coordination with the redevelopment of the Shinagawa Station North Exit district and the Tamachi Station area, a scenario is emerging in which the "Shinagawa–Takanawa–Sengakuji–Tamachi" corridor in southern Minato Ward functions as an integrated international exchange hub. As a destination for inbound tourism demand and a candidate location for international business expansion, attention on this area is expected to grow even further.
Sengakuji Station Improvement Works | Platform Width to Double
A critical piece of public infrastructure being developed in tandem with the urban redevelopment project is the Sengakuji Station improvement works. Jointly undertaken by the Tokyo Metropolitan Bureau of Transportation and Keikyu Corporation, these improvements will double the current platform width from approximately 5 meters to approximately 10 meters. The upgraded station is scheduled to begin service in fiscal year 2027, with the ticket gate concourse also being expanded.
Despite being a key transfer station where passengers on the Toei Asakusa Line and Keikyu Main Line converge, the current Sengakuji Station has long faced safety challenges during rush hours due to its narrow platforms. By planning the platform expansion and the construction of the redevelopment building above as an integrated project, a fundamental improvement in station functionality and the creation of an attractive urban space at ground level are being achieved simultaneously. This is a prime example of the "joint public-private urban transformation" that Type 2 Urban Redevelopment Projects make possible.
Improved station convenience has a direct impact on surrounding property values. Reduced congestion, enhanced barrier-free access, and the creation of commercial space through concourse expansion will positively influence both rental demand and property valuations in the station area. For property owners, the progress of these improvement works is information worth monitoring closely as a key factor in long-term asset strategy decisions.

Impact on Southern Minato Ward's Real Estate Market
What impact will the Sengakuji Station district redevelopment have on the real estate market in southern Minato Ward (Takanawa, Shirokane-Takanawa, and the Shinagawa area)?
Rental housing market: The "anticipatory pricing-in" effect ahead of the building's completion (fiscal year 2031) has the potential to push up rental levels for surrounding properties. In particular, for condominiums and apartments within walking distance, as the effects of Takanawa Gateway City's opening compound with growing awareness of the Sengakuji redevelopment's progress, the pool of prospective tenants is expected to deepen. Demand capture from high-income demographics — particularly employees of foreign-affiliated companies and commuters to the Shinagawa and Tamachi areas — can be anticipated.
Office market: Once the office component (mid-level floors) of the redevelopment building becomes operational, office supply in the Takanawa area will increase. While this could create competitive pressure for existing office buildings nearby, the enhanced visibility and brand power of the area as a whole will also broaden demand. Over the long term, as the district's positioning as an international exchange hub solidifies, a fundamental uplift in office demand across southern Minato Ward is expected.
Condominium market: The residential component of the redevelopment building (385 units) will be offered as condominiums for sale. As a high-rise tower residence at 145 meters, pricing is expected to target affluent and ultra-high-net-worth buyers. In terms of post-completion asset value, the brand advantages of integrated development with Takanawa Gateway City and the pedestrian deck connection to JR Takanawa Gateway Station are likely to command a significant premium.

INA's Perspective | Assessing the Long-Term Value of the Sengakuji Area
My interest in the Sengakuji Station district redevelopment is not simply a matter of scale. The essence of this project lies in the ingenuity of the Type 2 Urban Redevelopment framework, which enables the simultaneous delivery of station improvements, urban infrastructure development, and mixed-use facility construction. The Tokyo Metropolitan Government, as the executing body, underwrites the public infrastructure improvements that would be difficult for the private sector to achieve alone, while combining them with private-sector construction expertise and capital. This model represents one of the most effective formulas for urban regeneration in Japan.
The Sengakuji area has already arrived at the "threshold of transformation" with the opening of Takanawa Gateway City. With the addition of the Sengakuji Station redevelopment, southern Minato Ward is poised to evolve into an area that functions as a nexus along the "Shinagawa–Takanawa–Sengakuji" international exchange corridor. While completion is scheduled for fiscal year 2031, the real estate market prices in these expectations well before a project is finished. For investors and property owners with a long-term perspective, I believe that gathering information and considering strategic decisions at this stage carries significant value.
