TOKYO — Naoto Masujima was appointed director and executive general manager, Overseas Business Division, for Nisshin Flour Milling Inc., effective June 25.

In this role, he will be in charge of existing overseas companies’ operations and development of new businesses. Mr. Masujima was previously in globalization, Corporate Planning Division, Nisshin Seifun Group, Inc.

Masashi Koike, executive officer, deputy general manager, Corporate Planning Division, has been appointed to Mr. Masujima’s previous position.

Nisshin Flour Milling Inc., a subsidiary of Tokyo-based Nisshin Seifun Group Inc. (NSGI), is Japan’s largest flour milling company. The company has been in the process of building an international flour milling network, with bases already operating in Canada, Thailand, the United States and New Zealand.

Nisshin acquired the Rogers Foods, Ltd. milling business in Canada in 1989. In 2012, Nisshin acquired Miller Milling Co., which operates flour mills in Fresno, Calif., and Winchester, Va., and in February 2013 it purchased Champion Flour Milling Ltd. from Goodman Fielder for NZ$51 million.

In May 2014, Nisshin’s Miller Milling business acquired four additional mills — the Los Angeles U.S. flour mill of Horizon Milling L.L.C. and Oakland, Calif.; Saginaw, Texas; and New Prague, Minn., mills of ConAgra Mills. When acquired these four mills had a combined daily flour milling capacity of 58,600 cwts.  In addition to turning Nisshin into a top U.S. flour milling company with nearly 100,000 cwts of daily milling capacity, the $215 million transaction was pivotal in allowing an even larger transaction to move forward — the creation of Ardent Mills through the combination of the remaining milling operations of ConAgra Foods, Inc. and Horizon Milling L.L.C.
