MUMBAI, India — Two Japanese developers, Mitsui Fudosan and Sumitomo Realty & Development, are stepping up their bets on India with a new round of projects in the country’s financial capital, after prime office rents in Bandra Kurla Complex surged 14.2% year over year during the third quarter of 2025. The Mitsui Fudosan India push, previously focused on a single office partnership in Bengaluru, now collides with Sumitomo’s $6.5 billion Mumbai pipeline as both groups chase yield in a low-cost construction market.

Mitsui Fudosan India makes a Mumbai push, moves away from Bengaluru.
Mitsui Fudosan’s India jaunt began in 2020, when it entered into a US$1 billion joint venture with RMZ Corp to acquire a 50% interest in the RMZ Ecoworld 30 office project in Bengaluru, one of its largest investments to date. The company’s own announcement of the visit at the time cast India as a high-growth market fueled by a young, growing workforce.
Five years from that date, Mitsui is now eyeing land in Mumbai and the Delhi region and weighing new investments of ¥30-35 billion ($190-$225 million) for new Indian projects, recent a Reuters report published by The Economic Times says. that Mitsui managers toured Mumbai in November scouting for sites, a sign that the Mitsui Fudosan India push is entering a more aggressive phase.
Unlike many of the world’s large investors, which prefer to buy completed towers, Japanese developers have been willing to take construction risk, in order more easily to realize buildings designed on their own terms — from open-floor-plate steel structures that offered a canvas for different businesses to do with as they chose (after partition walls were built) in the 1930s and ’40s, up through energy-efficient heating and cooling systems. For Mitsui Fudosan, it is about deploying patient capital in a market where building top-quality offices in Mumbai costs a fraction of what it does in Tokyo, London, or New York.
Sumitomo’s Mumbai bet of $6.5 billion rides BKC’s rent boom
Sumitomo Realty & Development, Japan’s third-biggest developer, has already invested approximately $6.5 billion in five projects across Mumbai — including marquee office buildings at and around Bandra Kurla Complex (BKC) and fresh acquisitions near the proposed Navi Mumbai airport. Its signature BKC tower is being advertised as a world-class Grade A hub in Bandra East, with a steel frame that supports broad, column-free floor plates – and analysts expect it to attract rents 30–40% above average local rates.
It’s against the background of a red-hot leasing market: CBRE Global Prime Office Rent Tracker shows BKC leading the Asia-Pacific region with a 14.2% annual rise in prime rents in the third quarter of 2025, ahead of Tokyo’s central five wards and Delhi NCR. The report cites tight supply and a ‘flight to quality’ into top-end buildings. Recent deals support that — Qatar National Bank renewed a BKC lease at ₹775 per sq. ft, and Swiggy recently paid as much for its BKC office space sublease. ft. per month, among the highest of any commercial lease in India, and JPMorgan has pre-leased two floors at the Sumitomo Tower at a starting monthly rent of about ₹6.9 crore, well before construction is complete, for what would be considered a marquee anchor tenant.
The Mitsui Fudosan India push offers the security that foreign capital lacks elsewhere.
Foreign capital is increasingly flowing into Indian real estate, with international investors attributing the trend to robust GDP growth, rapid urbanisation, and improved office take-up. An Economic Times explainer on overseas bets in Indian real estate issues a fresh round of “buyer beware” about Japanese investors, calling them the newest standout entrant because of Mitsui Fudosan’s plan to invest up to ¥35 billion through joint-venture-led office projects.
This moment has been years in the making. In 2020 itself, RMZ Corp and Mitsui announced their decision to forge a 50:50 joint venture valued at nearly $1 billion to build commercial offices across Bengaluru, Mumbai, and Delhi, which was then described as Mitsui’s first bet on India. Recent coverage in The Times of India portrayed Mitsui Fudosan India’s move as a modest beachhead, not a dash for the coast.
The announcement in Mumbai has come on the heels of Sumitomo’s aspirations: In 2019, the group shelled out approximately ₹2,238 crore to buy a 3-acre plot at Bandra Kurla Complex (BKC) in what was among India’s most expensive land deals by price per acre at that time, setting a benchmark for foreign demand for core commercial land. An early tracking of Japanese investors’ foray into Indian realty found that the deal was the inflection point in Mumbai’s office land market and a breeding ground, as it were, for the multibillion-dollar build-out we are seeing today.
With BKC rents accelerated more than in just about any other Asian business district, and construction costs remaining reasonable, Mumbai is the natural next step for the Mitsui Fudosan India push — and a test to see if Japan’s patient, design-driven developers can carve out a lasting space in one of the world’s most cutthroat office markets.
