Lixil Group Corp., which agreed to buy bathroom-fixture makers American Standard Brands and Grohe Group last year, is studying another overseas acquisition to boost revenue from emerging markets.

The planned deal will help Tokyo-based Lixil achieve its target of increasing sales from emerging markets to more than 30 percent of its revenue, from about 20 percent now, Chief Executive Officer Yoshiaki Fujimori said in an interview Monday. The company could spend tens of billions of yen on its next takeover, Fujimori added.

Since Fujimori joined the company in June 2011, Lixil has spent $5.3 billion buying companies in the U.S. and Europe to counter slowing demand at home amid the shrinking population.
