Description
Junichi is a young man who works as a clerk at a rental video store, and it is there that he first encounters the air doll after she has come to life. His background is largely unremarkable within the context of the story; he appears to lead a quiet, solitary life in the city, with his job at the video store being the primary window into his character and daily routine. He is depicted as a gentle, kind, and somewhat introverted individual. His demeanor is calm and his interactions are characterized by a soft-spoken and patient nature, which stands in stark contrast to the more possessive and emotionally needy behavior of the doll's owner, Hideo. This gentleness is central to his role, as he treats the living doll not as an object but as a person from their first meeting.

Unlike the doll’s owner, who seeks a companion to fill a void of loneliness, Junichi appears to accept his own solitude with a sense of quiet resignation. His motivations are not driven by grand ambitions or dramatic needs. Rather, he seems to be seeking a simple connection, which he finds in the doll after she begins working at the store. He is drawn to her because of her unique perspective on the world; her naive questions and wonder at everyday things, such as the meaning of the word "beautiful" or the concept of death, offer him a new way of seeing his own mundane reality. He accepts her unusual nature and the fact that she is an air doll without shock or judgment, perhaps because he too feels a sense of emptiness or hollowness that makes her literal emptiness feel familiar rather than frightening.

In the narrative, Junichi serves as the primary catalyst for the air doll's emotional awakening. After she falls in love with him instantly, her desire to be close to him drives her to get a job at the video store, integrating her further into human society. Their relationship is chaste and tender, built on walks, conversations, and shared quiet moments, such as when he takes her to see the ocean after learning she has never been. He represents the ideal of a gentle, accepting love that she craves. A key moment in their relationship occurs when she accidentally cuts herself and begins to deflate. Rather than being horrified, Junichi calmly repairs the tear with adhesive tape and then re-inflates her by breathing air into her valve, an act that is both intimate and life-giving, cementing his role as her savior and the source of her new existence.

Junichi’s key relationship is exclusively with the living doll. While the doll is named Nozomi by her owner, the film rarely emphasizes this name in her interactions with Junichi, focusing instead on the purity of their connection. His role in the story, however, is tragic and serves as the film’s central irony. After they become close, the doll, who misunderstands the fundamental difference between her own constructed existence and human biology, decides she wants to do for him what he did for her. She believes she can let the air out of him and then refill him to give him the same pleasure or sense of renewal. In a fatal act of naive love, she cuts him with scissors, and when he begins to bleed, she tries to seal the wound with tape, just as he had done for her. In this way, Junichi’s development leads to the story's devastating climax, where his human fragility is fatally juxtaposed with the doll’s artificial resilience. He dies not from malice, but from the profound and tragic misunderstanding born of her love for him, leaving his body to be disposed of as if he were the broken object.

As a character, Junichi does not possess any notable supernatural or extraordinary abilities. His significance is defined entirely by his humanity and his lack of special traits. He is an ordinary, gentle young man whose simple kindness makes him the perfect object of affection for a being discovering life for the first time, and whose very real, fragile mortality ultimately underscores the film's meditation on what it means to be alive. He is described by some as being as quiet and passive as the doll herself, reflecting her own "cheap, doll-like beauty," which reinforces the theme that loneliness and a sense of being an empty vessel are not unique to a non-human character.
