Features of the Office


Attorney Makiko Mizuuchi graduated from high school in California as an exchange student, and later studied and obtained a Master of Laws degree majoring in Anglo-American Law under an Australian professor at a national university in Tokyo.


After her admission to the Bar in 2005, she gained broad experience as an attorney by representing clients in numerous cases, especially in the area of family law, at a number of law firms, including one specializing in family law in Tokyo and another established by the Okayama Bar Association. She has also worked to protect victims of domestic violence and the rights of elderly people and foreign residents in Japan by serving on various committees of bar associations and engaging in pro bono activities.


As a result of these experiences, Ms. Mizuuchi came to believe there were not enough neighborhood attorneys handling international family law cases, so decided to establish an office specializing in family law matters – especially divorce, child custody, inheritance, and Hague Convention cases – in Kawaguchi, Saitama Prefecture in the Greater Tokyo area. The office is approximately 30 minutes by train from Tokyo Station.


Ms. Mizuuchi currently serves as a member of the Hague Convention Working Group of the Japan Federation of Bar Associations (JFBA), and has been studying Hague cases through the research activities of the Group and by attending international family law conferences in Japan and abroad, such as a family law conference held at Metropolitan University, London in 2013 and the Fourth LAWASIA Family Law Conference held in Sapporo in 2014. She is also registered for the JFBA Lawyer Referral Service in relation to Hague Convention abduction cases.
