Message from our CEO

July 1, 2019

Thank you for taking the time to visit Shiodome Partners Shiodome Partners Gyoseishoshi Corporation’s official website. We are a corporation that provides advisory services on international taxation as part of various professionals that make up the Shiodome Partners Group. Our economy in Japan is facing many changes that can be hard to keep up with; that is why we are constantly working on providing the best services to ensure a smooth transaction for our clients.

There are an increasing number of corporations attempting to conduct business in Japan. Without proper knowledge of overseas accounting and tax, they tend to encounter pitfalls while navigating Japan’s business environment. They may also find themselves unable to enjoy the tax benefits that Japan offers to overseas businesses. As a member of PKF International, one of the world’s largest accounting networks, we work with over 400 member firms in more than 150 countries to support our clients.

If various experts continue provide their services individually in a disjointed fashion, they would not be able to keep up with the changes in business landscapes over the coming years.

Shiodome Partners continues to grow its network of professionals ranging from certified public accountants and certified public tax accountants, to lawyers, judicial scriveners, administrative scriveners, and certified social insurance and labor consultants, as well as offers its services in major languages such as English in Chinese, to be able to best respond to and meet the needs of our international business clients.

We look forward to your continued confidence and support in us.
