Why Aoba
Three reasons clients work with us
24 years of practice
Registered as a Gyoseishoshi (Certified Administrative Procedures Legal Specialist) since 2002. We have seen two decades of regulatory change in construction, immigration, healthcare and waste management — and we design filings that survive the next one.
A single point of contact
We work daily with certified public tax accountants, certified management consultants, social insurance labour consultants and judicial scriveners. When your matter crosses professional boundaries, we coordinate so you do not have to.
Long-term partnership
A filing is rarely the end of the story. We track renewals, annual reports and the next phase of your business. Many of our clients move from a one-off engagement into a continuing retainer.

We are authorised to prepare and submit applications to government agencies on behalf of clients — including visa and residence status applications when registered as an Application Filing Agent (申請取次行政書士) with the Immigration Services Agency.
