About us


Our principal goal is to obtain the best possible outcome for our clients. While that might sound obvious, it is easier said than done in today’s complex and constantly changing environment. We are not satisfied until we have realized the best interests of our clients by having a clear understanding of the background of each matter, clarifying and investigating the points at issue, making a convincing case, and succeeding in lawsuits or negotiations with the parties involved. We believe that the ability to provide the most effective legal advice is significantly enhanced by our flexible viewpoints, clear thinking, expertise, experience, mobility, communication skills, ability to respond to changes, and unbending sprit.

At Shiomizaka, we recognize the significance of teamwork. By combining the wealth of the highly specialized knowledge and experience that each attorney brings to the firm, we are able to provide innovative legal advice in a flexible and effective manner that is tailored to each individual matter while maintaining a broad perspective unfettered by any one particular field. We constantly strive to achieve extraordinary results for our clients as their most reliable advisor.
