Composed in 2015. It was premiered on May 30 of the same year in Fukuoka City by Kumiko Matsukawa (clarinet) and Minako Yahiro (piano). The composer states the following about this work: "This work aims to commemorate the 70th anniversary of the end of the war. Unusually for me, the expression contains quite direct irony. The title is inspired by Shuichi Kato's 'On a Fine Day,' but it is not a programmatic musical adaptation of the novel's content. However, war arrives in an ordinary daily life and deeply penetrates the mind and body engaged in that daily life. I could not help but feel such things in my daily life of composing."
