Hello,

My name is Shuhei Kojima, Representative Patent Attorney and founder of Kojima International IP Office, based in Tokyo, Japan.

Our firm is exclusively focused on trademark practice, with particular strength in Japanese domestic trademark filings and prosecution. We regularly advise and represent Japanese businesses in securing and maintaining trademark rights before the Japan Patent Office.

In addition, we work with foreign patent and trademark attorneys to support Japanese clients seeking trademark protection outside Japan, and we are keen to further develop professional collaboration with overseas practitioners in trademark matters involving Japan.

With a solid understanding of Japanese trademark law and practice, and a strong commitment to clear and timely communication, we aim to be a reliable point of contact in Japan for trademark-related collaboration.

If you are interested in exploring opportunities to work together, please feel free to contact us.

We look forward to hearing from you.

About Shuhei Kojima

Representative Patent Attorney, Kojima International IP Office

Trademark Strategy Consultant

After graduating from the Faculty of Law at Kyoto University in 1988, Shuhei Kojima joined Japan’s Ministry of International Trade and Industry (now METI). For the next 30 years, he was involved in policymaking and international negotiations across multiple government agencies, including METI, the Small and Medium Enterprise Agency, the Agency for Natural Resources and Energy, the National Police Agency, the Cabinet Secretariat, and the Ministry of Foreign Affairs. He has served in senior roles such as Director-General of the Hokkaido Bureau of Economy, Trade and Industry and Chief of the Tokushima Prefectural Police.

In 2021, upon registering as a patent attorney, he founded Kojima International Patent Office. Currently, he focuses on supporting small and medium-sized enterprises (SMEs) in protecting their brands through trademark registration, while also working as an advisor on economic security and crisis management—areas where he draws on his extensive experience in government.

His first book, “Win with IP — Trademark Strategy for SMEs and Startups” (2025), provides practical guidance for business owners and founders seeking to strategically build, protect, and expand their brands through trademark rights.

His personal motto is: "Don’t hesitate—once you go, you’ll understand."

He enjoys weight training and watching films.

He is originally from Shiga Prefecture and now lives in Tokyo.
