Abe, Ikubo & Katayama was founded by the representative partner, Shogo Abe, under the name of Ginza Law Office in 1959. Since then, we have represented numerous clients in litigations and negotiations, provided legal advices, and earned the full trust from those clients. The matters that we have dealt with are civil matters concerning general corporate advices, litigation and alternative dispute resolution, corporate turnaround and insolvency, intellectual property, life science, M&A, international practice, compliance & crisis management, finance, competition law, information law and labor law.
In 1991, the name of the firm was changed to Abe, Ikubo & Katayama. In 1997, the arrival of Emeritus Professor of Hitotsubashi University, Morio Takeshita as a specialcounsel added much more depth to our specialized areas of law. In 2000, we established Patent Prosecution Division (currently Intellectual Property Division) andenhanced our patent application and prosecution services.
We are now one of the leading law firms in Japan in intellectual property law and corporate related laws with more than 160 members consisting of attorneys at law patent attorneys and secretarial and managerial staff. Our clients include a diverse array of businesses such as manufacturers, financial institutions, distributors, construction companies and various enterprises in the service industry, both in Japan and overseas. We regularly provide legal services to about 400 Japanese companies as well as to overseas companies as the retained counsel.
Lawyer Shogo Abe passed away in February 2023, and Professor Emeritus Morio Takeshita passed away in October 2019.

We are well experienced in handling complex and large scale of lawsuits. We approach cases with determination and passion to "win" for our clients.
