In order to prepare for the filming, Ayano went through intensive training in kendo and body training to reduce his body fat percentage to just 7 percent over two months. This is the second time that he is working with Kumakiri since 2013's "Natsu no owari" and he's looking forward to the collaboration again. Likewise for Murakami who had aspired to work with Kumakiri since his debut, he revealed that he was very keen to play the role of Toru and would probably get jealous if the role had gone to another actor.
Filming was done at Kamakura City, Kanagawa Prefecture and expected to wrap up at the end of September.
