Why Aoba
Three reasons clients work with us
24 years of practice
Registered as a Gyoseishoshi (Administrative Scrivener) 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.
About
Working with a Japanese Administrative Scrivener
A Gyoseishoshi (行政書士), officially translated as Administrative Scrivener by the Japan Federation of Administrative Scriveners Associations, is a national-licensed legal professional in Japan. 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.
Aoba Administrative Law Office has been registered with the Kanagawa Administrative Scriveners Association since 2002. Mitsuhiro Saito, the principal, has handled cases across construction, immigration, medical and inheritance practice for 24 years. Our office is one minute from Ichigao Station on the Tokyu Den-en-toshi Line, about 30 minutes from Shibuya.
