All Japan Karafuto Federation, which had consisted mainly of former residents in Karafuto and their relatives, was forced to dissolve due to the aging of its members. It happened in the Year of Reiwa 4. All Japan Karafuto Federation (Abbreviation: Kabaren) was the largest group directly related to Karafuto, but its board of the directors decided to dissolve it. In 2015, members of the federation, who were worried about the future dissolution of it, gathered and formed the current All Japan Karafuto Research Organization (Abbreviation: Kabaken). The main purpose of Kabaken is to pass on the history of Karafuto to future generations. Anyone who is interested in handing down Karafuto history to the future generations is free to join.
