The massive earthquake of March 11, 2011 and the subsequent explosion at the Fukushima Daiichi Nuclear Power Plant. On July 17, 2013, the song was released on the Internet. At the time, the national election (the election for members of the House of Councilors) in Japan was just around the corner, and one of the issues at stake was the pros and cons of nuclear power generation. Unexplainable anxiety at that time. Distrust and anxiety towards society. A thirst for change. I wonder how the thoughts I wrote as if I were driven to do so have changed 10 years later. Have we changed, or have we not changed at all? Looking at each other and having a conversation with myself from 10 years ago. *This sound source that will be announced again is a different version that could not be announced at that time.
