In order to pass down the historical meaning of “Conquering the Devils and Attaining Enlightenment” (Goma-Jodo) to future generations, “Gōma Jōdō Kan” (Hall of Conquering the Devils and Attaining Enlightenment) (former Nagoya Commemoration Hall) was opened in Nagoya on December 8th, 2020. The building is the former company dorm Master Ryuho Okawa lived in for two years while working at the trading firm. It is also where he contacted and recorded messages from high spirits in Heaven that were then published and amassed the large readership that became the first members of Happy Science.
