Half Empty or Half Full
Half Empty or Half Full (Japanese: 半身反義) is a 2008 Japanese film directed by Kayo Takefuji. The production features a 90-minute runtime and utilizes a hybrid structure that combines documentary elements with fictional narrative.

Structure and Narrative
The film is divided into two distinct parts. The first half functions as a documentary focusing on the life and career of Tatsuji Yamagishi, a filmmaker known for his work on the official documentaries for the 1964 Tokyo Olympics and the 1970 Japan Expo. In this segment, Yamagishi, who is living in a hospital following a stroke that left him partially disabled, is interviewed and filmed by director Kayo Takefuji.

The second half transitions into a fictionalized narrative. Takefuji proposes an imaginative exploration of Yamagishi's life, casting actor Hideo Nishijima to portray a younger version of the filmmaker. This segment follows the younger character as he retraces aspects of Yamagishi's history, culminating in a scene where the character stands alone on a sand hill, prompting questions regarding the nature of freedom and fantasy.
