Oshima, Nishimura & Miyanaga PPC



Oshima, Nishimura & Miyanaga PPC is a trademark firm founded in 2014 through the merging of two trademark specialty firms, Atsushi Oshima & Associates (founded in 2006) and Nishimura & Miyanaga (founded in 2007).

Through the combination of these two ambitious firms, we set our sights to become Japan’s premier trademark specialty firm, not only in the quality and scale of our work, but in our position at the cutting edge of trademark management in Japan.

With trademarks at the core of our practice, and expertise in the closely-related fields of design and unfair competition, we provide unparalleled service to our many domestic and international clients. We are proud to offer a modern and professional range of services through the integration of the knowledge, experience and skill of all our attorneys and staff, along with enrichment from our wide global network.

We aim to understand the unique needs of each of our clients and to assist them in the creation, protection and enhancement of the value of their brands. We help to lead each client’s business to success through brand development and appropriate management, naming and logo design, acquisition of strong rights, and protection from infringement.

We can advise our foreign clients in English or Japanese on all matters relating to acquisition and management of trademark rights in Japan, and help them to navigate the Japanese trademark system with a clear understanding.

In addition to providing the highest quality services, we believe responding to our clients quickly and accurately is of paramount importance. Above all, we place all our efforts to provide exceptional trademark services to each and every one of our clients.

We thank you for your patronage and look forward to serving you in the future.
