Brief History

After serving as a judge for approximately nine years, during which he heard and decided a large number of cases, Mr. Idenawa turned to private practice and joined Yoshikawa Law Firm.

As a judge, he handled cases across a wide range of fields: civil litigation including corporate and labor disputes, insolvency, civil execution and provisional remedies, family cases such as estate division and divorce, and criminal and juvenile cases.

During his secondment to the Ministry of Justice, he served as a litigation attorney (a prosecutor attached to the Litigation Bureau), acting in a role comparable to outside counsel for the State, and engaged in preventive-justice support for government ministries and agencies.

Drawing on a judge's ability to analyze evidence and facts with precision and to foresee how litigation will unfold, together with the insight into dispute prevention and dealings with the authorities gained at the Ministry of Justice, he works on corporate disputes, labor disputes, misconduct response and other crisis management matters. His support is not limited to litigation after a dispute has arisen: from the first signs of a problem, he assists clients consistently through initial response, fact investigation, analysis of legal risk and formulation of a resolution strategy, pursuing solutions that are genuinely effective for his clients.
