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 not intentious 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. The judgment found that the defendant did not have an intention to possess Narcotics based on our claim that the defendant only had an intention to possess Designated drugs (Tokyo District Court). Immigration Control and Refugee Recognition Act states that any alien who has been convicted for violation of a provision of the Narcotics and Psychotropic Substances Control Act may be deported from Japan.
