The Montreal Hoshuko School (French: École Hoshuko Montréal Inc, Japanese: モントリオール日本語補習校 Montoriōru Nihongo Hoshū Jugyō Kō) is a Japanese supplementary weekend school in Montreal, Quebec. The members of the Montreal Shōkōkai (モントリオール商工会; Japanese Association of Commerce and Industry) manage and assist the administrative and financial aspects of the Montreal Hokusho and have done so since the school's founding. The Montreal Hokusho serves both Japanese nationals and Japanese Canadians. Classes are held at the Trafalgar School for Girls, where the weekend school rents space.
