Seisaku Kagaku Kenkyūjo

The Seisaku Kagaku Kenkyūjo ( Japanese 政策 科学 研究所 , German "Scientific Research Institute for Politics") was a faction of the Japanese Liberal Democratic Party (LDP) until 1999 . After its chairman it was also referred to as the Nakasone faction , Watanabe faction and finally as the ex-Watanabe faction .

1966 left Nakasone Yasuhiro together with other opponents of the re-election of Satō Eisaku as party chairman / prime minister, the former faction of Hatoyama Ichirō , the Shunjūkai . He founded his own faction under the official name shinsei dōshikai , which developed into one of the mainstreams of the LDP in the following years.

In 1978 the faction changed its name to Seisaku Kagaku Kenkyūjo , or Seikaken for short . When Nakasone became LDP chairman and thus prime minister in 1982, Sakurauchi Yoshio took over chairmanship. As a result of the recruit scandal , Nakasone finally lost control of the faction, and Watanabe Michio became the new chairman . After his death in 1995 no single one could assert himself at the top of the faction, which is why the faction continued to bear his name.

After the Yamasaki faction split off in 1998, most of the remaining members of the faction joined forces a year later with the Kamei group of Shizuka Kamei , itself a spin-off from the Seiwa Seisaku Kenkyūkai , to form Shisuikai (Murakami-Kamei faction).
