The Doyokai was formed when the Asahi Club and the Koshikai (which was the successor to the Konwakai), fearing the emergence of a maximal faction, Kenkyukai (in the House of Peers), joined forces to reach 53 members (two Dukes, three Counts, seven Viscounts, five Barons, 17 members by imperial decree, and 19 high taxpayers).
最大会派研究会_(貴族院)の台頭に憂慮を抱いていた朝日倶楽部と庚子会（懇話会の後身）が合同して53名（公爵2名・伯爵3名・子爵7名・男爵5名・勅撰議員17名・多額納税議員19名）にて結成された。
