When television did not yet exist, political speeches in public halls were always well attended. Audience members who could not enter the venue often overflowed into the vestibule and applauded the stories played over speakers set up outside the venue.

Particularly memorable was the night of the grand campaign speech held on February 7, 1930, hosted by the Constitutional Purification League, in which the various factions stood in attendance. The speakers were Katsutaro Yokoyama of the Good Governance Party, Chiyu Ito of the Association of Friends of Constitutional Government, Komakichi Matsuoka of the Social Democratic Party, Mitsu Kono of the Japan Masses Party, and Ikuo Oyama of the Japan Labor-Farmer Party, but the audience was most interested in Ikuo Oyama. The speeches proceeded smoothly up to Kono’s, but when it was Oyama’s turn to speak next, he failed to show up at the Hibiya venue because of the chaos at the Hongo venue where he was at the time.
Thus, Koichi Nakamura, a member of the same party, spoke on his behalf, but the audience was not convinced. On the day of the event, a 50-sen admission fee was charged, and a furor erupted as people demanded that their money be refunded immediately if Oyama did not speak at the event. It was late at night at 11 p.m. when Mr. Oyama finally rushed to the venue. He took the stage in a hurry and addressed the audience for 30 minutes, which finally satisfied the full house audience and dispersed. The time was 11:30 p.m., and this was the only time, ever, that the public hall was open this late. In the same year, Prime Minister Hamaguchi gave a major speech at a meeting of the Good Governance Party, and when the meeting was cleaned up after its closing, a surprising fact was recorded: there were almost 2 liters of shredded buttons.
