Osamu Umejima

Osamu Umejima rejoined White & Case in October 2003 after a two-year hiatus working at the Ministry of Economy, Trade and Industry (METI) of the Japanese Government. He assists clients with international trade matters, including WTO rules and dispute settlements, and antidumping, countervailing and other trade-related measures in the United States, EC, Japan, and other trading partners. He also advises on FTA and other custom issues, including country of origins, custom duties and classification, and import and export regulations. His experience in the government also enabled him to have successfully lobbied Japanese government agencies on regulatory issues on behalf of corporations and trade associations. These governmental agencies include the METI, the Ministry of Land Infrastructure and Transportation, and the Ministry of Agriculture, Forestry and Fishery.

He started practicing international trade and corporate law at White & Case in 1992 in Tokyo, but his first experience on international trade matters goes back to 1989. Upon joining White & Case, the practice areas he worked in were corporate, contracts, antitrust, labor, and intellectual property. He moved to the Washington, DC office of White & Case in 1995, where he practiced U.S. trade laws, including the antidumping law, countervailing law, and Section 337. Mr. Umejima led various antidumping cases on behalf of Asian respondents, and appeared before the US Department of Commerce, the International Trade Commission, the Court of International Trade, and the Canadian International Trade Tribunal. In 2000, Mr. Umejima returned to the Tokyo office of White & Case, where he continued practicing international trade and corporate laws, until he joined to METI in 2001.

Before rejoining White & Case, he assumed the position of Director – Antidumping and Related Rules in Multilateral Trade System Department, Trade Policy Bureau at METI. He coordinated and argued in various antidumping and countervailing duty cases before the Dispute Settlement Body of the World Trade Organization on behalf of the Japanese government, including disputes on US – CRS Sunset Review, US – CDSOA (“Byrd Amendment”), and other disputes in which Japan participated as a complaining party or as a third party. He has also handled negotiations for the Antidumping Agreement under the Doha Development Agenda of the WTO.

Trade Law Practice:

Government actions increasingly affect companies involved in the global trade of goods and services. Whether they’re negotiating multilateral, regional or bilateral trade agreements, or revising national laws and regulations, the involvement of governments frequently has a direct and profound impact on the rules governing international trade. While the ultimate goal may be a more liberalized trading system, the immediate result is just as likely to be a thicket of rules, procedures and exceptions. This can mean an even more difficult business environment.

The International Trade Group of White & Case helps clients manage the risks and maximize the opportunities associated with the increasing regulation of international trade in goods and services. Our practice, centered in Washington, DC but extending throughout the globe, provides a range of services designed to match the scope of global trade regulation and to answer the needs of our clients wherever and whenever they arise. White & Case also has one of the leading WTO practices in the world, which is led by the Geneva office.

Daiichi Law Office:

Since the foundation of Iechika & Takatori Godo Law Office back in 1964 (renamed Daiichi Law Office in 1966), we have steadily increased a number of our attorneys, and diversified the practice areas we cover, based upon the requests from our clients as well as prediction about the trends of our clients’ needs. Today, we have offices in Tokyo and Osaka with 30 lawyers and 20 support staff in total, and our practice has expanded to encompass almost all areas of the law, including cross-border transactions, take-over defense and patent litigation. We are proud of the efforts we have made in order to adjust instantly and flexibly to the rapid changes in society, and appreciate all the support from our clients, over the last nearly half-century.

The business environments surrounding Japan and the wider Asian region have changed drastically over the decades. When Daiichi Law Office was founded, we could not have imagined today’s rapid development of the Asian economies. Now, we are advising Chinese and Indian companies that are investing in Japan on Japanese financial and securities regulations. The business activities of our clients routinely involve crossing borders, and the dissemination of information technologies will accelerate as time goes on. We are intensely aware of the importance of keeping up with these and other changes, and are sincerely committed to ensuring provision of the highest quality of legal services for our clients.

As our name “Daiichi” suggests, we will strive to continue to be your “first choice” counsel.

We greatly appreciate your continued support.

Allen & Overy:

We’ll do that by staying one step ahead and by constantly challenging ourselves to bring new and original ways of thinking to the most complex legal challenges our clients face.

Over the past year we have worked with some of the world’s most sophisticated businesses on market-leading transactions that have changed their industries. This includes, advising on the largest oil refinery project in Vietnam (Nghi Son) and the joint venture between H.C. Starck and Vietnam’s largest private sector company, Masan Group; the ground-breaking creation of Abu Dhabi’s first Financial Free Zone, the Abu Dhabi Global Market; and representing Novartis in its successful patent battle with MedImmune over Novartis’s blockbuster drug Lucentis – to name just a few achievements.

We are able to build on the foundations of our long heritage to attract the most talented people and develop the high-performance culture necessary to innovate and change the face of business.

Our commitment to help our clients deliver their global strategies has seen us build a truly global network now spanning 46 offices in 32 countries. We have also developed strong ties with relationship law firms in more than 100 countries where we do not have a presence.

This network has allowed us to become one of the largest and most connected law firms in our peer group with a global reach and local depth that is simply unrivalled.

So when we talk about global coverage, we’re not just talking about having offices in some important cities around the world. We mean being able to combine our international resources and sector expertise to work on cross-border transactions directly in the markets and regions important to our clients.
