A Jiji Press exit poll has found that 46.9% of respondents turned to social media and video-sharing sites for information when deciding which party to vote for in Sunday's House of Councilors election in Japan.

Meanwhile, those who did not use such services at all or very much totaled 50.0%.

Of those who turned to social media and video-sharing sites, the largest proportion, at 23.9%, cast proportional representation votes for Sanseito, a small party that expanded its Upper House presence markedly in the election.

The Democratic Party for the People (DPP) came next at 16.5%, followed by the Liberal Democratic Party at 11.5%, Reiwa Shinsengumi at 8.8% and the Conservative Party of Japan at 8.2%.

The share stood at 7.0% for the Constitutional Democratic Party of Japan (CDP), 5.9% for Nippon Ishin no Kai, 4.4% for political organization Team Mirai and 3.7% for Komeito.

Of those who did not use such services for their voting decisions, 28.5% voted for the LDP, 17.4% for the CDP, 9.7% for the DPP, 8.1% for Nippon Ishin and 7.9% for Komeito.
