Mitsuhiro Saito
齋藤 光宏 / Registered with the Kanagawa Administrative Scriveners Association (第02092927号)
Registered as a Gyoseishoshi in 2002. Based in Aoba-ku, Yokohama, the principal has built a practice that spans construction licensing, medical corporations, industrial waste, foreign workforce and residence status, subsidies and inheritance — bringing together the legal paperwork and the management decisions that go with it.
The principal speaks Japanese as a native language and works in English for international matters. For visa and residence status applications, he is registered as an Application Filing Agent (申請取次行政書士) with the Immigration Services Agency, which generally allows the applicant to skip the in-person visit to immigration.

Why Aoba
Three pillars of our work
24 years of practice
Registered as a Gyoseishoshi since 2002. We have lived through more than two decades of regulatory change, and we design filings that survive the next one.
A coordinated team across professions
We collaborate daily with certified public tax accountants, certified management consultants, social insurance labour consultants and judicial scriveners. When your matter crosses professional boundaries, we coordinate.
A long-term partnership
Filings rarely end 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.
