Kokuhonsha

Membership of the Kokuhonsha included many of Hiranuma's colleagues from the Ministry of Home Affairs, important businessmen, as well as some of the most powerful generals and admirals, including generals Sadao Araki, Jinzaburō Masaki, Makoto Saitō, and Yamakawa Kenjirō with war hero and admiral Tōgō Heihachirō serving as honorary Vice Chairman.

[4] The Kokuhonsha published a monthly newspaper called Kokuhon, and acted as Hiranuma's political support group.

Kokuhon openly advocated a concept they called Kokumin Zentaishugi ("National Totalitarianism"), which aspired to the "inclusion of all sections of the Japanese state and society in one embracing whole".

"[5] However, after Hiranuma was appointed President of the Privy Council, he no longer needed the support of a political action group.

The February 26 Incident of 1936, during which time many prominent members expressed support for the insurrectionists, provided Hiranuma with an excuse to order the organization dissolved.
