Sonderhoff & Einsel

Tokyo, Japan

Sonderhoff & Einsel has provided legal services for over 100 years in Japan. Our attorneys are a multicultural and multilingual team of legal professionals who have a deep understanding of doing business in Europe, the US, and Japan.

At Sonderhoff & Einsel, nearly all of our attorneys have spent a majority of their careers at top global law firms or one of the big four Japanese law firms, and we therefore have a strong track record of providing goal-oriented and practical solutions for our multinational clients.

We also have a flat firm structure for the benefit of our clients as our professionals assume responsibility for their work and efficiently take the initiative when communicating advice to the client. Further, our legal experts work hand in hand with Sonderhoff & Einsel’s IP professionals and Sonderhoff & Einsel Tax Co.’s tax and accounting professionals, providing our clients with a one-stop shop for their legal, financial and IP needs.

In this ever-changing market environment, we believe that we are well-positioned to help our clients accomplish their objectives and protect their interests through our expertise in corporate and commercial transactions, M&A, litigation and dispute resolution, labour and employment law, healthcare law, intellectual property law, data protection and privacy law, aviation law (aircraft incidents and aviation finance), and finance.
