Media researchers and journalists have ramped up their efforts to identify dubious information on the internet related to Sunday's Lower House election in a bid to stem the spread of fake news affecting voter behavior.

Fake news, typically social media stories containing incorrect information, has been a major issue in recent elections in Europe and the United States, including the U.S. presidential race last year.

A project launched by the Japan Center of Education for Journalist and Hiroyuki Fujishiro, an associate professor at Hosei University in Tokyo, is listing fake news items related to Sunday's election on the JCEJ's website (jcej.info).
