Tokyo Family Court and Tokyo High Court awarded shared physical custody.

Tokyo Family Court and Tokyo High Court fully accepted our claims and awarded shared physical custody(this allows the children to live roughly equal amounts of time with both parents)based on a foreign state law.


We obtained the judgment which found the foreign defendant didn’t have an intention of possessing Narcotics in the criminal case.  

      Our attorney Honda (Chief) and attorney Sato served as the defense counsels for the foreign defendant accused of the possession of Narcotics and the judgment found the defendant didn’t have an intention of possessing Narcotics based on our claim that the defendant only had an intention of possessing Designated drugs (Tokyo District Court).
