Greetings
Shunsuke Kagei
Representative Partner
Effective July 1, 2025, our firm, which has long been a leader in the immigration field, merged with RSM Shiodome Partners Gyoseishoshi Lawyers Corporation, a member of RSM, the world’s 6th largest international accounting network. This strategic merger marks a new chapter in our mission to deliver advanced, one-stop solutions tailored to an increasingly global and complex environment.
Since our founding in 1992 by Masahito Nakai, we have spent over 32 years supporting the aspirations of individuals and businesses from around the world. With deep expertise in Japanese immigration procedures and a strong track record of success, we have guided countless clients through key transitions in life and business.
By combining our accumulated experience and trusted reputation with RSM Shiodome Partners’ international reach and innovative capabilities, we are now equipped to offer even greater value. Together, we aim to respond swiftly and precisely to the evolving challenges of immigration and compliance, serving clients both in Japan and overseas with enhanced quality and care.
In today’s digital era, we are also accelerating the use of technology to simplify procedures and strengthen our one-stop service model. With a diverse, multinational team, we remain committed to compliance and are implementing state-of-the-art information systems to ensure clients feel secure and supported every step of the way.
As Japan increasingly relies on international talent, we are dedicated to supporting the success of foreign professionals and contributing to the development of a more inclusive and vibrant society. On the occasion of this merger, our entire team reaffirms its commitment to excellence and client service.
We kindly ask for your continued support and patronage.
Masahito Nakai
Senior Adviser
Our main focus is to assist corporate clients in efficient and comfortable manner. Video conferences are conducted frequently, while opinion letters comprised of regulations, practices and theories written in English are issued upon request.
From the start, we have been pursuing a noble cause of providing (1) speed, (2) professionalism, and (3) friendliness at the same time in the course of performing our duties. And that still remains as our guiding motto today.
I would very much like to help build a new unique country with talented foreign citizens on the basis of Japan’s culture and tradition. Nakai Immigration Services (currently operating under the name RSM Shiodome Partners AS Co.) has been embodying such a vision, working as one multicultural team made up of people of most diverse backgrounds.

Information Security (ISO 27001)
Nakai Immigration Services LPC (currently operating under the name RSM Shiodome Partners AS Co.) is not a commercial company but a Legal Professional Corporation (LPC). We strive to offer the best services within the borders of the law and ethical code. We also have a contract with each of our staff to not divulge any information of our customers.
Unlike under the nondisclosure agreements used by commercial enterprises, both Gyoseishoshi Immigration Attorneys and their staff are subject to criminal penalties if client confidentiality is violated. We are therefore obligated by law to protect the private information of both individual and corporate clients, even after work has been completed. Our firm also currently has ISO27001 certification, which is an International Standard for Management Systems of Information Security.
Additionally, we have created a software with a database development company to draft application forms and manage such data, which maximizes our efficiency. Documents are digitized, and data of our clients and applications are jointly managed within internal and external servers under rigorous information protection standards.
