In the United States, interest in the life science field and demand for laboratory facilities have been increasing due to the experience of the Covid-19 pandemic and the rapid development of advanced therapeutic science. The Boston Area is the nation’s largest cluster of life science companies, venture capital firms, government agencies and educational institutions. The Seaport District of Boston, where the property is located, has been designated as an innovation district led by the City of Boston and is expected to continue to grow in the future.

The property is targeting LEED Gold Certification (an international building environmental performance rating index), Fitwel Life Sciences Certification, which evaluates the health considerations of laboratory building users, and WiredScore Platinum Certification, which evaluates the digital connectivity of the building. In addition, a long-term lease agreement has been signed with Eli Lilly and Company, a major global pharmaceutical company, as its Institute for Genetic Medicine, leading to a stable real estate asset.

Our company will continue to actively promote overseas real estate investment with an emphasis on “stability,” “sustainability” and “growth potential,” with the aim of building an optimal asset portfolio.

(*) Suitable structure and equipment for R&D applications such as installation of laboratory equipment, including ceiling height, load-bearing capacity, piping, etc.
