"the grown-ups of Summer" was filmed and released in 1997. As the first feature-length film work of Tetsuya Nakajima, it is obviously different from the typical Nakajima-style film. From the Tale of his wife to longing, Nakajima also tells bizarre stories in an almost crazy way. On the other hand, "Summer Adults" brings a summer feeling about growth from the perspective of children. In this debut, Tetsuki Nakajima also shows his mature narrative skills. Of course, this film, like the later works of Tetsuya Nakajima, is full of novel imagination.
