This Marks the JV’s Third Transaction to Meet the Growing Tenant Demand for Life Sciences and R&D Real Estate in Japan.

Tokyo, April 3, 2025 – Warburg Pincus, the pioneer of private equity global growth investing, and Eastgate Group, one of Japan’s largest privately owned real estate investment managers, today announced the acquisition of Shinagawa Seaside West Tower by their joint venture (“JV”) and the unveiling of the GRC brand for the JV’s properties. This acquisition represents the third transaction under the venture since its inception in 2023, expanding the portfolio to include high-quality innovation and R&D assets in both Yokohama and Tokyo.

In 2023, Warburg Pincus, through the Warburg Pincus Asia Real Estate Fund (“WPARE”), and Eastgate Group, through Eastgate Capital Management, established the JV to leverage their combined expertise to address the significant undersupply of specialist real estate for lease to tenants in the life sciences, hi-tech, and manufacturing industries across Japan’s key cities. With the Shinagawa Seaside acquisition, the joint venture now manages over 1 million square feet of gross floor area and has over US$300 million of assets under management.

Operated under the GRC brand, the venture’s assets are strategically located in major innovation and R&D hubs, catering to a diversified tenant base across a wide range of industries seeking to attract and retain high-skilled talent. From designing and delivering bespoke spaces to managing specialized properties, GRC is committed to delivering state-of-the-art infrastructure, including a wide range of spaces with modular unit sizes and both dry and wet labs, to meet the evolving needs for high-quality, high-specification space of both international and domestic tenants.

In November 2023, the venture acquired its first asset, GRC Yokohama Bay Research Park, a 17-storey mixed-use commercial building spanning over 540,000 square feet of gross floor area. The property currently houses a large number of tenants from specialist industries, such as engineering, technology, government research, and manufacturing, offering base specifications suitable for both wet and dry lab use. Building on the success of Yokohama Bay Research Park, the venture acquired the soon-to-be-renamed GRC Yokohama Science Cube in December 2024. This 78,000 square feet facility, located adjacent to Center Kita Station in Yokohama, is set to be transformed into a cutting-edge R&D and medical facility. The latest acquired asset, Shinagawa Seaside West Tower, is an 18-storey commercial building in Tokyo’s Shinagawa district. It offers over 410,000 square feet of gross floor area with superior structural specifications, capable of accommodating both dry and wet labs up to biosafety level 2.

Aligned with the venture’s strategy, GRC properties aim to deliver the consistent quality and service demanded by tenants operating critical on-site functions. Key features include customized spaces, dedicated mechanical and engineering riser spaces for ventilation, requisite water, gas and power provisions, heavy-duty floor loading and goods elevators, and specialist building operations to accommodate the daily needs of tenants.

Takashi Murata, Managing Director, Co-Head of Asia Real Estate and Head of Japan at Warburg Pincus, said, “We have built a high conviction in Japan’s life sciences and R&D real estate sector, which is underpinned by several secular trends including a rapidly aging population, strong growth in the healthcare market, and a significant shortage of R&D and lab space for lease. Both Warburg Pincus and Eastgate are early movers in the life sciences and R&D space with over 20 years of combined experience in investing in and managing such assets. By leveraging Warburg Pincus’ deep platform-building experience and operational expertise and Eastgate’s strong track record and local resources, we believe that GRC is well-positioned to meet the evolving needs for high-quality, specialized life sciences and R&D facilities in Japan among a diversified group of tenant base.”

Shozo Sekine, Founder and CEO of Eastgate Group, said, “As one of the first movers in this space, having managed R&D assets for more than 15 years, we have observed first-hand the critical under supply of high-quality, well-managed R&D facilities and the resulting rental premium they command. We are excited to partner with Warburg Pincus to establish this joint venture in Japan, leveraging Eastgate’s extensive operational expertise, strong track record in the sector and deep local knowledge with Warburg Pincus’ proven experience, global resources and established track record in scaling real estate platforms in Asia. We look forward to capitalizing on our combined strengths to support GRC’s continued growth and deliver long-term value to our tenants and investors.”
