宮澤喜一
In 1991, Mitsuzuka ran for the LDP president, but lost the election, and Kiichi Miyazawa became the president of the party. In 1994, he ran for the prime ministership. However, due to the allegations of involvement in the construction scandals of 1994 his bid was not successful. Although he was not charged, criticisms about him became public. Mitsuzuka was appointed secretary general of the party by then LDP president Kono Yohei in 1996.
