The tax practice of Nagashima Ohno & Tsunematsu is renowned for its broad coverage of a variety of tax-related matters, ranging from tax planning for various commercial transactions to tax disputes and tax litigation cases arising from differences in opinion with the tax authority.
At our firm, the Tax Practice Group (“TPG”) gathers together some of the well-regarded practitioners in Japan. We have a deep pool of talented professionals, which includes a former justice of the Supreme Court, a former senior official of the Japanese tax authority, current or former professors of leading law schools in Japan, lawyers who have worked in tax departments of leading law firms in the U.S, and a lawyer who was involved in international tax policy development at international organizations. We continuously strive to combine and share our rich professional knowledge and experience in tax law, and thereby, provide our clients with high-quality legal services. As testament to our efforts, many foreign tax publications have recognized our tax practice as having an unparalleled reputation, surpassing all other law firms in Japan.
