Before We Say Goodbye is a novel by Toshikazu Kawaguchi and the fourth book in the beloved Before the Coffee Gets Cold series. Set once again in the magical Café Funiculi Funicula in Tokyo, the story follows a new group of patrons who are given the rare chance to travel back in time—if they sit in a special seat and return before their coffee gets cold. Each visitor has unfinished business from their past and hopes to find closure or reconnect with someone important before it’s too late.

The book weaves together four touching, character‑driven tales: a husband with something important left unsaid, a woman longing to say goodbye to her dog, a woman wanting to answer a long‑lost proposal, and a daughter seeking reconciliation with her estranged father. Through these intertwined stories, the novel explores themes of love, regret, memory, forgiveness, and the bittersweet beauty of embracing moments we can never truly change, even if we’re allowed to revisit them.
