During a speech on March 3, 2014, in support of Toshio Tamogami's bid for the governorship of Tokyo, Hyakuta stated that the Nanjing Massacre "never happened", and stated that the Tokyo War Crimes Trials were a "sham" to cover up US war crimes such as firebombing and the atomic bombings of Hiroshima and Nagasaki. He also stated that he didn't see a need to teach such things to children, as they should be taught what a great country Japan is. He said that claims about the Nanjing Massacre were brought up at the Tokyo War Crimes Tribunals only to cancel out the crimes the US had committed. A press officer at the US embassy in Tokyo described Hyakuta's views as "preposterous".
