It's been 3 months since the 3.11 earthquake. June 11 saw large-scale anti-nuke protests all round the country. Many protesters were singing the singer-songwriter Saito Kazuyoshi's (斉藤和義) anti-nuke anthem "Zutto Uso Datta" (ずっとウソだった trans. They've been lying all the time).
This song was originally titiled "Zutto Suki Datta" (ずっと好きだった trans. I've been loving you all the time). This parody video by Saito himself was uploaded on YouTube on April 7th and quickly spread among young people.
