Corporate Background

Marubeni Utility Services, Ltd. was established in 1998 through the merger of three corporations in the Marubeni Corporation’s nuclear group. As a Marubeni group trading house specializing in the nuclear field, we offer nuclear-related products and services, excluding nuclear fuel, mainly to electric power companies and heavy electric plant manufacturers in Japan. We supply overseas products involving a high degree of technical expertise to domestic power companies, and we are renowned as a unique trading house that has a wealth of technical knowledge in nuclear-related businesses. We compete against – and from time to time work with – domestic plant manufacturers who have strong relationships with electric power companies. We sometimes even provide plant manufacturers with superior technologies and products – a unique business practice.
