Message

As a judge, I have long handled civil cases. Among them, the Minamata disease lawsuits I was involved in in Kumamoto and Niigata left a particularly strong impression on me, and I will never forget the plaintiffs’ attempts to rise up from their difficulties.
In the third Minamata disease case in Kumamoto in 1987, I drafted the judgment as the chief judge, and in the fourth Minamata disease case in Niigata in 2011, I presided over the hearing of the first Minamata disease case in which a settlement was reached between the government and plaintiffs. The look of relief on the plaintiffs’ faces remains in my memory.
He has also handled a number of domestic affairs cases. He was troubled by the treatment of juvenile cases he handled when he was an assistant judge, and has devoted himself to resolving domestic affairs cases with serious conflicts at the Tokyo Family Court Guardianship Center and the Yokohama Family Court, among others.
With my experience as a judge in both civil and domestic cases, I will provide legal services that get to the bottom of the facts and protect the rights of my clients to the fullest extent possible.
