The reason why Japan has the ending of Cape Brothers and Sisters is because the film reveals the ending. According to relevant public information, the movie "Brother and Sister on the Cape" ended when my brother received a phone call, and the open ending left a lot of imagination for the audience. Katayama revealed that during the filming process, there was always a clear arrangement for the ending, so my brother said a line after receiving the phone call, but later deleted it, hoping to leave it to the audience to imagine.
