East Goes West
Mori, which operates businesses ranging from office leasing to hotel operations and residential sales, has been expanding its US portfolio since its American debut in 2017 with the purchase of two office blocks in Boston, Massachusetts spanning 825,000 square feet.
In July of last year, the Tokyo-based firm notched one of the largest asset sales in the San Francisco Bay Area when it sold the HQ@First office complex in the Silicon Valley hub of Menlo Park to private equity giant KKR for a reported $535 million.
In announcing its first DC acquisition in March, Mori had reiterated its goal set in 2016 of buying as much as JPY 200 billion (now $1.4 billion) worth of properties overseas by 2027.
Mori DC deal was the second major acquisition of US office assets by an Asian investor this past week, with Singapore’s GIC said to have backed Workspace Property Trust’s $1.13 billion purchase of 41 suburban office properties earlier last week.
