All major national parties have managed to obtain at least one of the PR seats in Tōhoku since the introduction of proportional voting in 1996. The region also contains several strongholds: Aomori in particular is a typical "conservative kingdom" and leans towards the LDP alongside with the Western prefectures along the Sea of Japan coast; Iwate is the home of Ichirō Ozawa, former NFP, LP and DPJ president and a "Democratic kingdom" having also the first prefectural parliament in Japan where the Democrats managed to obtain the status of strongest party in 2007.
