American Homebuilders Are Being Scooped Up By Japanese Firms In Deals Worth Billions—here’s Why

Japanese homebuilders are on a buying spree of American firms, in a trend that's only accelerating as the U.S. faces a shortage of 4.03 million homes.

Since the start of 2026, three Japanese firms have announced deals to snap up homebuilders, including Sumitomo Forestry Co. Ltd.'s plan to acquire Tri-Pointe Homes Inc. in a $4.5 billion deal.

The housing shortage in the U.S. is a prime opportunity for the Japanese companies, which are locally faced with a shrinking population who are aging out of their homebuying years.

"Here stateside, we have a housing shortage in the millions of homes while in Japan these builders would struggle to find buyers," says Joel Berner, senior economist at Realtor.com®.

"Building homes in America is a ripe business opportunity compared to doing so in some other countries."

But, it's more than population demographics driving the acquisitions. Many of these Japanese names are positioned with the support and resources that bolster their new U.S. companies.

Japanese firms target regional homebuilders

In addition to Sumitomo's plan to acquire Tri-Pointe, the firm has also scooped up half a dozen regional builders in recent years.

In a separate deal, Stanley Martin Homes, a U.S. homebuilder acquired by Daiwa House in 2017, bought North Carolina-based United Homes Group in a $221 million deal.

Then, an affiliate of Iida Group Holdings Co. Ltd. announced it would acquire Utah's Wright Homes.

In a statement, Iida Group spoke highly of Wright Homes, in particular its regional focus.

"The northern part of Utah Lake in Utah, where WH Group primarily operates, is one of the places in the state where the demand for housing is fairly strong as it is near the center of major highways connecting large cities in Utah, providing commuting convenience," the statement reads.

"In addition, Utah, with its high GDP growth ratio and much lower unemployment ratio than the national average, is expected to see the strong demand for housing continue, driven by steady migration from other U.S. states."

In the process of its buy, Sumitomo has become the fifth-largest U.S. homebuilder. It has also leapfrogged Sekisui House, which surged up the list of largest homebuilders in 2024 when it acquired MDC Holdings, also known as Richmond American Homes, in a $5 billion cash deal.

Sekisui House CEO Yoshihiro Nakai spoke highly of that strategy at the time, arguing the firm could become "a one-of-a-kind entity in the U.S. by combining Japanese and U.S. technologies and, above all, sharing our passion for providing quality housing."

America's homebuilders are declining in numbers

The homebuilders cited fundamentals of the under-built U.S. housing market for driving their acquisitions.

"The Company’s Group has thought of business expansion in overseas markets as one of the growth
strategies since the domestic housing market is expected to the mature phase from the growth phase against the backdrop of a declining birthrate and an aging population," Iida Group said in its statement.

California fund manager Hennessy Funds also determined that the U.S. housing market offers a lucrative ramp-up. It singled out Sekisui, Sumitomo, and Daiwa in particular with potential for "significant" growth. These firms already have established manufacturing for homebuilding products they can pair with U.S. builders.

The U.S. homebuilding industry itself faces consolidation, with some large homebuilders growing in market share. Harvard University researchers estimated the number of homebuilders fell 22% from 2002 to 2017. That meant a loss of almost 19,000 firms.

And now, the top 100 homebuilders account for half of all sales from just a third two decades ago, Harvard found.

Given those trends, Hennessy said acquisitions are smart for Japanese firms. They can bring engineering skills, deep pockets, and manufacturing capacity to strengthen the U.S. firms. Their integrated structures mean raw material procurement and access to capital is easier for them.

The trend is even stronger amid the economic tumult of the last few years. Thanks to the rising cost of capital, which impacts smaller builders more than larger ones, more acquisitions are possible, Berner says.

"The likely targets would be smaller regional builders who are already well-established and have done significant land acquisition: ones that are ready to build and are just awaiting a cash infusion," Berner says.
