A Song to the Sun

Kaoru Amane, Erika Sawajiri, lives with Xeroderma Pigmentosum, a condition that forbids direct sunlight. She spends her days in shade and her nights awake, turning to music as a lifeline. Each night she sets up on the sidewalk near a busy station, strumming her guitar and singing for passersby, turning the city’s quiet hours into a stage for her voice. Through her bedroom window, she notices a high school boy with a surfboard who, with his friends, makes a ritual of the ocean every morning before the sun grows strong. One evening, she summons the courage to introduce herself to the mysterious boy without revealing her illness, and he answers with his own name: Kōji Fujishiro, Takayuki Yamada. When her friend nudges her home, they linger by the window to watch Kōji and his circle of friends. Kaoru confides her life-altering condition, and her friend jokes that perhaps she attends the same school, hinting at a chance to get closer to the boy who has quietly captured her attention.

The next night, Kaoru waits by the bus stop as the city settles into a slower rhythm. Kōji arrives on his scooter, their first real conversation awkward and earnest in equal measure. They exchange shy smiles, and a promise forms: he would return to listen to her sing again when the school holidays begin. When they finally meet again, they discover that another flashy street performer has commandeered Kaoru’s usual spot, but Kōji doesn’t let the setback derail them. Instead, he proposes a trip into the city to show her sights she has never seen, and soon she steps into a public square where the crowd swells as she sings. The moment is electric—a substantial audience cheers, claps, and leans in to hear every note. Afterward, they walk along the coastline, the ocean’s vastness echoing the growing closeness between them as Kōji asks her out on a proper date.

Their night together ends with sunrise watching over the sea, and Kaoru hurries back to the safety of her home as the day begins. The next moment brings a harder truth: Kōji learns about Kaoru’s condition, and the weight of that knowledge lands on him with surprising force. He resolves to help her pursue music, even if the path is fraught with medical and logistical hurdles. He discovers a recording studio where she could lay down a debut single, and he begins taking on small jobs to save money for the project. Her father, moved by concern and curiosity, invites Kōji to dinner one evening, and the two men share a genuine moment of care and resolve. In the quiet that follows, Kōji reveals his dream for Kaoru’s CD, and Kaoru slowly recognizes how deeply he cares for her, his sincerity cutting through her doubts.

As Kaoru’s health worsens, her hands lose sensation and she can no longer strum the guitar that has defined her nights. Yet she insists that her voice remains intact, a beacon even when the body begins to fail. In the studio, she makes a moving request: she asks her friends and family to step back, to give her space to record and to wait for the finished CD as a testament to her life. Time passes, and Kōji follows through on his promise, guiding Kaoru to a beach where he surfs as a form of tribute to the girl who has given him a new rhythm to his days. The protective suit she has kept for years is finally worn, a stark symbol of the compromises she has lived with. Kaoru is now in a wheelchair, the suit a visible shield against a sun that never truly leaves her behind. She complains the suit is getting hot, and her father urges her to shed it so she can run free, but she chooses to endure a little longer. As she tries to stand, she stumbles, and Kōji rushes to catch her. In a tender moment, her stumble is revealed to be a feint, and she laughs at his surprised face, a small spark of her old defiance returning in the glow of their connection.

Ultimately, Kaoru’s story reaches its quiet, heartbreakingly human end as she succumbs to her illness. She is laid to rest in a coffin filled with sunflowers, a final image that feels both bright and poignant. The CD she dreamed of releasing finally arrives into the world, carried by friends and family who gather to honor her memory. In the closing scene, Kōji races toward the waves, the memory of her voice looping through his mind, a lasting soundtrack to a love that illuminated the night for as long as it could.
