Before the Coffee Gets Cold
is a 2015 novel by . It tells of a café in Tokyo that allows its customers to travel back in time, as long as they return before their coffee gets cold. Summary 
In a narrow back alley in Tokyo lies a café called Funiculi Funicula. In the café, customers have the opportunity to travel back to a time of their choosing, as long as they follow a long list of rules. There is only one seat in the café that allows time travel; the seat is only available when the ghost that usually occupies it goes for a toilet break; once back in time, customers can't leave the seat; the only people in the past who can be met are people who have visited the café; whatever happens in the past, the present won't change; and, most importantly, the customer has to return to the present before their cup of coffee goes cold (around 1 hour). The novel follows the stories of the café staff, notably the barista Kazu, and four different customers. The first customer is a businesswoman named Fumiko, tries to repair her relationship with her boyfriend after he left the country for a job in the United States. The second customer, a nurse named Kohtake, tries to find a letter her Alzheimer-stricken husband wrote. The third customer, a bar owner named Hirai, who tries to initiate a conversation with her sister, whom she's been avoiding. The fourth customer is one of the café co-owners, named Kei, tries to go to the future to talk to her unborn daughter. Through the stories of its four characters, the author delivers a compelling message: the past cannot be altered, but the future remains open and full of possibilities." History
