"Takashi gets a big thumbs up from us"

"An excellent and very measured practitioner"


Takashi has been a partner in the corporate crisis management group of Nishimura & Asahi, the largest law firm in Japan, since 2013. After joining the firm in 2010, he has dealt with a number of large-scale and complex corporate scandal matters, both cross-border and domestic. He assists companies in responding to various kinds of emergency situations; including international cartels; bribery of foreign public officials; window dressing; insider trading; market manipulation; product data falsification; money laundering; and other misconduct by executives or employees in or outside Japan by aiding in internal investigations, communicating with the governmental authorities concerned or proposing recurrence prevention measures for such misconduct. He also helps companies to implement and improve their preventive measures, and advises on how to build and strengthen global compliance systems and measures, including preventive measures concerning bribery of foreign public officials.

Takashi served as a Japanese public prosecutor from 1992 to 2010. In that capacity, he investigated and tried a variety of high-profile cases involving major financial crimes, insider trading, cartels, and bribery of foreign and domestic public officials while serving at the special investigation department of the Tokyo District Public Prosecutors’ Office, and other prosecutors’ offices in Japan. He was also engaged in international affairs, including communicating on behalf of the Japanese government with the OECD working group on bribery in its monitoring of the OECD Anti-Bribery Convention’s implementation in Japan; negotiating various international criminal conventions, including the Convention on Cybercrime; and dealing with many mutual legal assistance and extradition cases in criminal procedures while serving at the criminal legislation division, and the international division, of the Criminal Affairs Bureau of the Ministry of Justice. In addition, during his assigned period as a first secretary of the Permanent Mission of Japan to the UN and other international organisations in Geneva under the Japanese Ministry of Foreign Affairs from 2001 until 2004, he worked closely with the Office of the UN High Commissioner for Human Rights and international NGOs in a range of human rights matters, including negotiation of various human rights instruments.

Takashi is a graduate of Keio University (LLB, 1990) and the International University in Geneva (MBA, magna cum laude 2004), and is admitted to the bar in Japan. He has written various publications in the areas of corporate crisis management, white-collar crime and Japanese labour law.

Takashi has been recognised in WWL: Japan (2019-2020), in the business crime defence and investigations categories; and WWL: Investigations (2019-2020).
