S1, E4: A newspaper article states the Kanto region will sink within half a year. Deputy Prime Minister Satoshiro and Chief Cabinet Secretary Naganuma are desperate to identify the article’s sources, while Shiina tells Prime Minister Higashiyama to hold a press conference. No definitive timeline or probability figures are given, but people descend into mass hysteria when the prime minister mentions the possibility of Kanto sinking. Higashiyama entrusts the Japan Future Promotion Conference with drawing up countermeasures and Tokiwa leads the development of a quick response. Tadokoro candidly discusses Kanto sinking on TV, and Tokiwa cannot control his anger when he reveals information not announced by Higashiyama. He also cannot shake the suspicion Amami is the source for the newspaper article.
