In the late 1980s, Kazuo Ishiguro was stuck on the novel that would become The Remains of the Day. He and his wife, Lorna, worked out a drastic fix they called the Crash, a four-week stretch where he did almost nothing but write. The bulk of the book came out of it.

The Direct Answer
The Crash was a four-week writing sprint: 9am to 10.30pm, six days a week, with the outside world shut out.
Ishiguro laid out the plan in his 2014 essay for The Guardian, looking back at how the novel got finished.

Four Weeks, One Rule: Keep Writing

By the mid-1980s Ishiguro had two novels behind him and a full writer's life on top of the work: correspondence, invitations, the small admin that quietly eats a week. The manuscript wasn't moving fast enough. So he and Lorna cleared the calendar and set rules that sound almost monastic. He described them plainly.

During the Crash, I would do nothing but write from 9am to 10.30pm, Monday through Saturday. I'd get one hour off for lunch and two for dinner.

The isolation was the whole point. He didn't open his mail, wouldn't go near the phone, and nobody came to the house. Lorna, on top of her own busy schedule, took over his share of the cooking and housework so the only thing left on his plate was the next sentence. Six days on, one day off, for a month.

Why It Worked

The schedule bought him something more valuable than raw hours. It bought total immersion. When your only job for weeks is the world of your book, that world starts to feel more solid than the one outside the window, and the writing stops being something you switch on and off. Ishiguro has said the Crash produced some of his most imaginative work, because the ideas had room to surface and grow without anything interrupting them.

It helped that he wasn't starting cold. He'd done the thinking, the character work, the false starts. The Crash was the shove that turned a stalled project into a draft, and he credits part of it to timing: the sprint landed at the moment he knew just enough about the book to run with it.

That intensity was the exception, not his everyday habit. For the rest of the time he kept a steadier rhythm. See the full Kazuo Ishiguro writing routine for how he works on an ordinary day.
