When Inukai was made prime minister in December 1931, Hatoyama became Minister of Education. Inukai was assassinated in the [[May 15 incident]] and Suzuki was elected to succeed him as Seiyukai president, but he didn't become prime minister, as the [[genrō]] [[Prince Saionji]] preferred to nominate Admiral [[Makoto Saito]]. Hatoyama continued in his post and became involved in a controversy in March 1933 when he had a professor at [[Kyoto Imperial University]] dismissed for leftist views. In March 1934 he was forced to resign due to alleged corruption in the [[Teijin Incident]], which eventually led to the downfall of the Saito cabinet.{{sfn|Magill|2014b|pp=1574–1576}}<ref name=Teijin>{{cite book |last=Mitchell |first=Richard H. |date=31 March 2002 |title=Justice in Japan: The Notorious Teijin Scandal |url=https://books.google.com/books?id=Zo40clDmxiUC |publisher=University of Hawaii Press |page=77 |isbn=978-0824825232}}</ref>

When Suzuki was once again passed over as prime minister, this time in favour of Admiral [[Keisuke Okada]], the Seiyukai moved into the opposition, even expelling members who accepted positions in the new cabinet. By this time Hatoyama had become one of the most powerful men in the Seiyukai as the right-hand man of his brother-in-law.<ref name=Teijin></ref>

The Seiyukai took major losses in the [[1936 Japanese general election|1936 general election]] and this led Suzuki to resign the following year. Hatoyama and [[Chikuhei Nakajima]] were the leading candidates for the presidency, but to prevent schism a "Presidential Proxy Committee" was formed consisting of Hatoyama, Nakajima, [[Yonezō Maeda]] and [[Toshio Shimada]]. As there was too much antipathy against himself, Hatoyama decided to support [[Fusanosuke Kuhara]] as president. But in March 1939 the opponents of Kuhara and Hatoyama had Nakajima declared president in contravention to party rules. As a result, the party was split between a "reformist faction" led Nakajima and an "orthodox faction" led by Kuhara.<ref name=Fukui></ref>
