Chiba 6th district

Background The Liberal Democratic Party nominated Hiromichi Watanabe, the incumbent member of the House of Representatives from Chiba 6th district, as its candidate. In opposition parties, the Constitutional Democratic Party and the Ishin planned to field candidates.

The CDP initially tried to nominate Yukio Ubukata, an incumbent member of the House of Representatives from Southern Kanto proportional representation block and the Chairman of the Chiba Prefectural Federation of the CDP. However, Ubukata was criticized for his remarks on North Korean abductions of Japanese citizens. When Ubukata discussed the abduction of Japanese by North Korea at the rally just before the general election, he mentioned Megumi Tokota, one of the abductees and a symbol of North Korean abductions, and insisted "Nobody thinks she is still alive. None of the (ruling) Liberal Democratic Party’s lawmakers do, either. If she were alive, (North Korea) would have returned her." In addition, Regarding the abductees who returned after negotiations, Ubukata said, "We should have returned them to North Korea after a certain period of time, as promised with North Korea," adding that Koizumi's decision to refuse to return them to North Korea was wrong. The family association of abductees protested Ubukata's remarks, and Sakie Yokota, the mother of abductee Megumi Yokota, said, "I was surprised that there were Japanese like this. We believe the abductees are alive." CDP Secretary-General Tetsuro Fukuyama and Yuko Mori, who heads the party’s headquarters on the issue of abduction, responded with an emergency statement that distanced the party from his comments. They said his remarks were “completely at odds with the party’s thinking” and “deeply hurt families of the abductees and all people involved with resolving the abduction issue.” The party said it has severely reprimanded Ubukata. As a result of a slip of tongue, Ubukata resigned as chairman of the Constitutional Democratic Party's Chiba prefectural federation and left the Constitutional Democratic Party.

The Ishin nominated whose father is , a former member of the House of Councillors, as its candidate. Following Ubukata's departure from the CDP, the Japanese Communist Party, which had not fielded a candidate for election cooperation with the CDP, also fielded a candidate.
