Professional Biography:

Leaders in Law, the leading platform in its field, is delighted to welcome Kaoru Haraguchi as our exclusively recommended & endorsed International Succession Law Expert in Japan.

Kaoru Haraguchi, a founding attorney of Haraguchi International Law Office, located in Tokyo, has many passions. If you ask him his life, you would have to hear hours of his adventures with his blunt humor – It is the story of a boy with broken dreams of becoming a table tennis player who went to the University of Chicago, worked on Wall Street and in England, teamed up with China’s largest insurance company to collect debts, became friends with a great Mongolian judge, was admitted to the bar, and went on to defend the energy industry in a promising land of sun and wind. He is working from 5am to 10pm, 24/7, to do his job to the fullest for his clients – His fighting spirit never ceases to live: once it used to be for victory for himself, but now for clients. His lengthy, funny but informative interview (although in Japanese) is cited in https://souzoku-bengoshi.guide/topics/5653347. This is a portal site to search for lawyers specializing in inheritance and legal advice to learn his life. This interview vividly describes the real world of international legal issues, along with his personality and philosophy.

His strength is that he can give you a practical advice, through his pierce but humane eyes through his abundant experience of finance, diversity and his personal life, along the winding road. Recently Cross-border inheritance has received much more attention than cross-border transactions. Cross-border inheritance involves complex and diverse legal issues. In particular, inheritance law in Japan, which inherited continental law, differs greatly from Anglo-American law, which has no clear-cut provisions, and there are many unresolved issues. On the other hand, inheritances between Japan and the U.S. and the U.K. occur on a daily basis and on a permanent basis.

His passion finds no end. Now he is planning to have annual seminars in Los Angeles in 2024, for Japanese who has difficulty with inheritance matters.
