Masui & Partners was established in December 2021 by attorneys with experience at some of the largest law firms in Japan and other law firms in the United States.
In order to provide better legal services in the area of corporate legal affairs, We believe that in order to provide better legal services in the area of corporate legal affairs, it is extremely important to take into account the client’s business philosophy and other factors, as well as to have an accurate understanding of the business model of each industry.
We believe that the role of lawyers is not only to respond to individual cases, but also to examine the causes of legal issues in depth based on the client’s business model, and to make recommendations to prevent similar problems from occurring again.
For strategic legal matters such as launching new businesses, we not only examine the business plan in light of the current laws and regulations, but also uncompromisingly examine and recommend what legal strategies are possible to realize the business pursued by the client.
We believe that the role of an attorney is to help clients who have contacted us or requested us to consult with them so that they can be freed from negative emotions such as worries and anxieties and smile even a little more than before they consulted us. In order to fulfill this role and purpose, I try to (1) listen carefully to my clients and share their concerns with them, and (2) present concrete solutions and options to their concerns in an easy-to-understand manner, rather than explaining the law in an arcane manner.
We hope that you will feel free to contact us with any concerns you may have.
