From today's Columbia Journalism Review daily email:

[T]he [Wall Street] Journal’s Suryatapa Bhattacharya visited the Manuscript Writing Cafe, in Tokyo, where visitors with writer’s block set a timed word-count goal for whatever they’re working on and pay a twenty-two-dollar fine if they don’t meet it.

Takuya Kawai, the cafe’s co-owner, “offers his customers three levels of supervision” while they work, with the harshest akin to “being seated in an examination hall under a proctor’s vigilance.”

The article, unfortunately, is behind a paywall, with only the first two paragraphs and the photo visible. Here's the photo caption:
"Kyoko Ohtagaki prefers the Manuscript Writing Cafe to co-working spaces because there are fewer people, no music, and traffic from a nearby highway sounds like white noise."
