Tokyo Office

Major Practice Areas
Tax / Environment / Securities / Renewable Energy


Yasuhiko Okada has extensive experience in government administration as well as legislation. For example, he has held numerous high-level and complex positions, including serving as a National Tax Examiner to conduct tax inspections, serving as a Tax Office Superintendent to impose taxation, and serving as Chief of the Taxation Administration Agency to secure impartiality in taxation. He was also involved in legislation relating to tariffs, financing, securities, and environmental issues. Based upon such experience, he excels at resolving clients’ issues by taking into consideration the intent of his clients and also by looking retrospectively into the legislative intent of the relevant laws. Such analysis takes time and effort; however, it can be extremely effective when dealing with difficult tax issues, as well as in dealing with the relevant authorities with regard to environmental issues which are subject to different rules and regulations.

Furthermore, Mr. Okada is familiar with practical aspects of business management, since he had been serving as an outside director of several listed companies, as well as on an independent committee on takeover defenses for years.
