Fujiyama, an elderly man, attends the "Yodamari" elder care program within a shopping mall. He sports noticeably grey, long, puffed-up hair, typically wears reading glasses, and dresses in tan pants and a vest. His hearing impairment causes him to speak at an extremely loud volume, potentially masking his fundamentally calm and kind nature.

He constantly carries an empty record sleeve labeled "YAMAZAKURA." This sleeve holds profound personal importance, containing the last vocal recording of his late wife, Akiko Fujiyama. His search for the missing disc becomes a central focus, driving him to comb the entire mall without success until the summer festival day.

Fujiyama once owned a vintage record shop, reflecting his deep connection to music and cultural history. However, he grapples with progressive memory loss, intensifying his desire to hear his wife's voice before her memory fades entirely. The record's eventual discovery behind a refrigerator ends in accidental shattering and emotional turmoil, though a functional copy is later found repurposed into a wall clock at the care center. This allows the recording to play during the festival, fulfilling his wish and triggering a poignant recollection of his past with Akiko.

His relationship with the teenage protagonists, Cherry and Smile, is pivotal. Their assistance in locating the record and facilitating its playback underscores his role in bridging generational gaps and cultural continuity. The resolution of his arc emphasizes themes of memory preservation and emotional catharsis.
