We are pleased to announce that Moore Shisei group changed its corporate brand name to ‘Moore’ as of January 1, 2020.

Moore Shisei, a member of Moore Global since 1992, is a full service accounting firm that began operations in 1978, and has provided over 40 years of high-quality professional services to our clients.

Located in the heart of Tokyo, Moore Shisei is comprised of 15 partners and more than 70 staff members, the majority of whom are either Certified Public Accountants or Licensed Tax Accountants.

Moore Shisei has a wealth of experience in a wide variety of industries, including specialized knowledge in many areas and countless achievements in providing services to Japanese and international clients. By combining this diverse experience with Moore Shisei’ s own style of personal service, we are confident of our ability to consistently offer high-quality professional services. 

Moore Shisei serves as a key firm in Moore Asia Pacific by providing leadership and business connections within and across the region and providing a strong presence on the JICPA committee. 

Mika Yamada, serves as the representative partner for the international team in addition to her regional counsel position within Moore Asia Pacific and as the global tax leader for the organization.

We are always keen to develop business and relationships in the following areas even in light of the current difficult circumstances present across the world. 


Foreign investment in Japan has been increasing in recent years in part due to the 2020 Tokyo Olympic Games and the 2025 Osaka World Expo. We have been closely working with global clients in almost every industry who desire to  take a part in these events.

At Moore Shisei, we have a Japan desk to offer support to our clients and other Moore Global member firms in coordinating the business for existing and potential Japanese clients, mainly to help solve business culture and communication problems.


Historically, Japanese businesses have been growing steadily with technology invented by SMEs and unlisted companies. The growth of these companies continues even under the current severe economic circumstances across the world. Many SMEs continue to expand operations worldwide.

We have established a strong reputation for providing services to SMEs in the areas of corporate tax consultation, compliance, and transfer pricing.


Often, global companies choose to work with the Big 4 because of the brand names. However, Big 4 firms are often not able to meet all of their client’s expectations as they fail to provide prompt attention to their client’s business needs. Moore Shisei Tax Corporation has an international team who are able to support their client’s continuous growth by providing services such as, day-to-day accounting, payroll, advisory, tax services, and coordination with legal professionals.

Moore Shisei is ready to be your business connection in Japan!
