The film is based on the same-titled novel by Honda Tetsuya and will be shot on location at the Chita Peninsula in Aichi Prefecture this summer. The novel is based on a real story featuring the lead character Hironobu (Takasugi) who finds a strange camera in the recycling shop owned by his grandfather which is said to take the longest panorama pictures in the world. The camera was developed by the late Yamamoto Shinichi and is able to take a 360 degree panorama shot. One of the photos taken using this camera measured 145m and is the Guinness record holder for being the longest photo in the world. Since that day, Hironobu's uneventful life takes on new colours. Takeda Rina will be playing Hironobu's cousin Atsuko.
Takasugi revealed that he had done some research on the Chita Peninsula as soon as he knew about the filming location and is looking forward how the beautiful scenery will complement the story. He is especially excited about checking out the sunflower fields there. When asked to comment about his character, Takasugi described Hironobu as someone who lacks self-confidence and doesn't dare to try anything nor say whatever is on his mind. The part about Hironobu being shy is one of the traits which he can identify with since he's also like that in real life.
As for Takeda, she described Atsuko as someone who is vastly different from her own character as Atsuko is very mature and cheerful. As such, she will try her best to play this role and work hard with Takasugi to make a good movie.
