Tsutsumi Law Office is a fresh and innovative law office founded by Yuki Tsutsumi, an attorney-at-law admitted in Japan, who has a wealth of practical experiences and strengths in cutting-edge areas such as AI (Artificial Intelligence), IT, and esports (electronic sports).

AI


The use of AI (Artificial Intelligence) in business is increasing, and various legal issues related to AI are occurring.
However, the characteristics of AI are not understood sufficiently.
The contract negotiations regarding AI development projects are sometimes disrupted, due to the lack of understanding of AI, for example, unrealistic contract conditions are insisted by one party.
Our office has a lawyer who has experienced an in-house legal counsel at an AI vendor and is a member of AI and Law Society.  We respond quickly, accurately, and reasonably to AI-related matters.

ESPORTS


Esports (Electronic sports) is on the rise in Japan as well.
Our office supports legal affairs of esports related companies and will accelerate esports legal affairs in the future.
The esports industry has its own unique legal issues, such as the issues related to the tournaments with prize money (the Criminal Code (gambling) and the Act against Unjustifiable Premiums and Misleading Representations), Entertainment Places Act and Act on Control and Improvement of Amusement Business, etc., as well as the handling of the copyrights.

STARTUP


Venture business and start-ups are not the miniatures of large companies.
The legal work for venture business and start-ups also varies from the legal services for large or traditional companies.
The process of transforming society through innovation involves various difficulties.  A wide range of legal issues arise which need to be resolved. Our firm has a wealth of experience in both in-house work experience of start-ups and advice from the viewpoint of the private practice.  We provide the services that meet the needs of venture and start-up companies.
