Grade A office rents in Tokyo's central five wards have reached record levels in the first quarter of 2026, driven by sustained demand from global financial institutions and technology companies expanding their Asia-Pacific footprints. Data from CBRE Japan shows average asking rents for premium office space in Chiyoda, Chuo, Minato, Shinjuku, and Shibuya wards rose 8.3 percent year-on-year to JPY 38,500 per tsubo per month.
Demand Drivers
The surge is led by global financial firms taking advantage of Japan's favorable regulatory environment and the country's position as a gateway to the broader Asian market. Goldman Sachs recently signed a lease for an additional three floors at the Toranomon Hills complex, while Blackstone expanded its Tokyo office by 40 percent to accommodate its growing Asia real estate team.
Technology giants are equally active. Google's Japanese subsidiary has committed to a 15,000-square-meter pre-lease at the upcoming Shibuya Upper West development, scheduled for completion in late 2027. Amazon Web Services is consolidating its multiple Tokyo locations into a single 20,000-square-meter headquarters in the Marunouchi district, one of the largest single-tenant deals in years.
Supply and Vacancy Dynamics
Despite a significant development pipeline, vacancy rates in Grade A buildings have tightened to 2.1 percent, down from 3.8 percent a year ago. The absorption has been remarkably strong, with net take-up in 2025 reaching 420,000 square meters, the highest figure since the post-financial crisis recovery in 2013.
However, the supply picture is set to shift. Approximately 1.2 million square meters of new Grade A office space is scheduled for delivery between 2026 and 2028, including major projects at Toranomon-Azabudai, Tokyo Station North, and the Shibuya redevelopment area. Analysts are divided on whether demand can keep pace with this incoming supply.
The Weak Yen Factor
Japan's persistently weak currency, trading near JPY 158 to the US dollar, has been a significant tailwind for the office market. For multinational corporations, Tokyo office costs in dollar terms remain substantially below comparable space in Singapore, Hong Kong, and Sydney, making it an attractive location for regional expansion.
Cushman and Wakefield estimates that Grade A office space in Marunouchi costs approximately USD 75 per square foot annually, compared to USD 120 in Singapore's Marina Bay and USD 95 in Hong Kong's Central district. This price advantage has been a key factor in leasing decisions for cost-conscious global firms.
Investment Market Activity
The robust occupier market has translated into strong investment demand. JLL reports that Tokyo office transaction volumes reached JPY 1.8 trillion in 2025, a 22 percent increase from 2024, with foreign investors accounting for roughly 35 percent of purchases by value. Cap rates for prime Marunouchi and Otemachi assets have compressed to 2.8 percent, reflecting intense competition for trophy properties.
Singapore's GIC has been particularly active, acquiring three office buildings in central Tokyo for a combined JPY 280 billion over the past 12 months. Canadian pension funds CPPIB and CDPQ have also expanded their Tokyo office portfolios, attracted by the combination of rental growth prospects and the potential for yen appreciation.
Outlook
Market consensus points to continued rental growth of 4 to 6 percent for the remainder of 2026, though the pace may moderate as new supply enters the market. The Bank of Japan's cautious approach to interest rate normalization is expected to keep financing conditions supportive, maintaining the appeal of Tokyo office assets for both domestic and international investors. Analysts at Nomura Real Estate note that the current cycle has further room to run, particularly in the technology and finance-driven submarkets of Shibuya and Marunouchi.
