Our lawyers have authored or co-authored a number of newsletters, articles, books and other materials covering a wide range of legal areas to address the latest legal developments and increasingly diverse and complex issues.


We regularly hold seminars and offer lectures through various formats, such as online streaming.


Pro Bono

Protecting Fundamental Human Rights and Realizing Social Justice

We at Nagashima Ohno & Tsunematsu actively engage in pro bono and other public service activities to fulfill an extremely important social responsibility as lawyers to protect fundamental human rights and realize social justice.

With social change and development, the expected social responsibilities of lawyers are also changing and expanding. To facilitate the timely implementation of a broader range of activities, in addition to conventional public service activities, in response to such societal needs, we have established the Pro Bono Promotion Committee and actively promote pro bono activities by our lawyers and staff members.

Moreover, we believe that law firms, similar to corporations, are in a position to address SDGs (Sustainable Development Goals) as members of society. Through our pro bono and other public service activities, we, therefore, are committed to contributing to the improvement of access to justice and the realization of an inclusive society, in which diversity is accepted and every individual is respected.

Pro Bono

Our lawyers are actively engaged in pro bono activities, in which they support organizations and individuals who carry out socially beneficial activities, by leveraging the knowledge and know-how they have cultivated through their daily practice as lawyers. Our firm has established a system to certify and support a variety of pro bono activities by each lawyer, enabling our lawyers to easily participate in pro bono activities.
