This website is managed by Makiko Mizuuchi, a Japanese attorney (Bengoshi) who is also licensed in California. While operating within a firm primarily focused on corporate law, she collaborates with experienced colleagues to provide legal assistance in international matters involving Japanese jurisdiction.
A core aspect of this practice is its integration into the global legal community. Makiko Mizuuchi has been a Fellow of the International Academy of Family Lawyers (IAFL) since 2017. This professional network, combined with the firm’s foundational expertise in corporate and financial matters, supports the handling of complex cross-border cases with the necessary professional rigor.
While the practice has a particular focus on legal issues involving the United States (specifically California), it also handles a wide range of international matters involving other jurisdictions. Our expertise includes:
International Inheritance: Assisting overseas heirs with Japanese probate, asset transfer (bank accounts, real estate, etc.), and regulatory compliance.
International Family Law: Handling cross-border matrimonial matters, property division involving multi-jurisdictional assets, and International Adoption procedures.
The mission is to provide clear, actionable Japanese legal advice to overseas clients and foreign legal practitioners, ensuring that complex international transitions are handled with professional competence.
