Japan's former Prime Minister Koizumi Junichiro has repeatedly called for current Prime Minister Abe Shinzo to make an explicit decision to get out of nuclear power. Koizumi's full-scale press conference on this matter, held on November 12 in front of 350 journalists, shook up the Abe cabinet. It continues to do so, judging by the tendentious commentary it continues to attract. Koizumi forced the cabinet to address an item they clearly wanted to finesse for the time being. But the substance of Koizumi's over hour-long event has not yet received the attention it merits. This article puts Koizumi's talk in context, showing that his position is shared by all the former Japanese prime ministers, including Nakasone Yasuhiro. Most important, contrary to the claim that Japan's choice is either gas or nuclear, Koizumi highlighted the ongoing deployment of radical efficiency and renewable energy as the proper path forward. And the accelerating rollout of smart cities across Japan suggests that Koizumi and his colleagues are standing on the right side of history.
1 The English-language coverage of the issue has been spotty at best, and largely dominated by observers sympathetic to the Abe cabinet and either inattentive to the content of Koizumi's press conference or simply unaware of .

8 Koizumi's press conference is viewable - in the original Japanese (no translation yet available) - at several YouTube sites. In the link cited in this footnote, Koizumi's discussion of renewable energy and advanced energy conservation options already being deployed in Japan are concentrated between 08:00-20:00. His discussion of Amory Lovins’ Reinventing Fire, whose Japanese translation Koizumi got from LDP member Kohno Taro, is at 40:00-42:00.
