《如果和母亲一起生活》是由山田洋次执导，吉永小百合与二宫和也等主演的日本电影，于2015年12月上映。 　　该片改编自作家井上ひさし的作品，讲述了在长崎负责助产士工作的伸子与在原子弹爆炸中去世的儿子浩二的亡灵之间发生的故事。 　　 　　 　　In 2015 Ryuichi Sakamoto composed the music for Nagasaki: Memories Of My Son, the latest film by legendary Japanese filmmaker Yoji Yamada whose career has spanned six decades and over 80 films. Yamada is perhaps the last director to have lived through what is now known as the Golden Age of Japanese cinema – a period that gave rise to Kurosawa, Mizoguchi and Ozu. The film tells the story of Nobuko Fukuhara, a mother who has lost her son in the atomic bombing of Nagasaki. It is an intimate character study of Nobuko, whose son begins to communicate to her as a ghost. 　　 　　Ryuichi Sakamoto was thrilled when Yoji Yamada approached him for this project. This beautiful soundtrack by the legendary composer evokes a nostalgic landscape of the humble everyday life of Japanese people while successfully paying homage to the film music of the Golden Age of Japanese cinema.
