Jul. 23, 2010


Main Contents

As previously disclosed in its Report of Foreign Private Issuer on Form 6-K filed on May 6, 2010 by Mitsui & Co., Ltd. ("Mitsui") with the U.S. Securities and Exchange Commission (the "SEC"), a third-party semi-submersible drilling rig, known as the Deepwater Horizon rig, which was conducting exploration work on the Mississippi Canyon 252 block in the Gulf of Mexico, experienced an explosion during April 2010, which sank the rig and resulted in spill of hydrocarbons from the well. Since the explosion, there has been an on-going, large-scale well-control and clean-up effort. MOEX Offshore 2007 LLC ("MOEX Offshore") holds a 10% minority non-operating interest in the Mississippi Canyon 252 lease on which the Deepwater Horizon rig was drilling. MOEX Offshore is a wholly owned subsidiary of MOEX USA Corporation, which in turn is wholly owned by Mitsui Oil Exploration Co., Ltd., in which Mitsui holds a 69.91% equity interest.

On July 22, 2010, Naoki Ishii, President of MOEX Offshore testified at a hearing before the Subcommittee on Federal Financial Management, Government Information, Federal Services and International Security of the U.S. Senate Committee on Homeland Security and Governmental Affairs with respect to the Deep Horizon incident in the Gulf of Mexico. The statement prepared and submitted on behalf of MOEX Offshore that is part of the hearing record is attached to this Report on Form 6-K.

Given its indirect equity interest in a non-operating interest holder of the lease on which the Deepwater Horizon rig was drilling, and in light of the ongoing investigations into the facts and circumstances surrounding the incident, the many pending lawsuits and the uncertainty as to the proper application of the provisions of the operating agreement relating to the well that affect the respective rights and responsibilities of the three holders of interests in the lease for costs associated with the incident, Mitsui is currently unable to estimate the potential liability of MOEX Offshore or its affiliates, if any, for the costs associated with the Deepwater Horizon incident in the Gulf of Mexico. Therefore, Mitsui is unable, at this time, to determine the impact, if any, the incident will have on its future operating results, financial position or cash flows.
