Hayato Ikeda
The GHQ ordered the dissolution of his previous groups and schools, and Yasuoka himself was purged on the ground of his involvement in the Ministry of Greater East Asia. In 1949 he organized the "Shiyukai" (Friends of Teacher); this group has continued to this day (2012) and includes a Hokkaido Shiyukai, Kansai Shiyukyokai and Himeji Shiyukai. After the war, he was asked to write the policy speeches of many prime ministers. He also became a spiritual guide and teacher to many prime ministers, including Shigeru Yoshida (who called Yasuoka "old teacher" in spite of Yoshida's being 20 years senior), Hayato Ikeda, Eisaku Satō, Takeo Fukuda and Masayoshi Ohira. He was reluctant, however, to speak of this.
