From the start, we have been pursuing a noble cause of (1) speed, (2) professionalism, and (3) friendliness at the same time in the course of performing our duties. And that still remains our guiding motto today as well.

Since I began my business as an Immigration Specialist in March 1992, the number of foreign people residing in Japan has nearly tripled. It has been my great pleasure to communicate with thousands of people with different backgrounds from overseas and to learn a variety of things. Working with my clients continuously expands my horizons, and this is why I continue to do what I do. Finally, this country decided to open doors to accept a reasonable number of foreigners in recent times. 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 has been embodying such a vision, working as one multicultural team made up of people of most diverse backgrounds

If your company is experiencing any difficulties or have any concerns about Immigration matters, please feel free to contact us. We will be delighted to assist you.

Nakai Immigration Services LPC 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.
