In one of the most significant and high-profile lawsuits in Japanese history, the firm is representing the directors of Tokyo Electric Power Company (TEPCO) in defending a derivative lawsuit filed by TEPCO’s shareholders claiming compensation in the amount of ¥22 trillion ($145 billion). The claim is for damage allegedly caused by the directors’ failure to foresee a disastrous tsunami arising from the Fukushima Nuclear Power Plant incident that took place in March 2022, and to take appropriate measures to prevent the occurrence. The court is expected to determine whether the electric power company’s directors should be held liable for one of the most serious incidents in Japanese history. The developments in the lawsuit have attracted extensive media coverage.
Notable litigation clients include Central Japan Railway Company and Koyo Automatic Machine.
