For most people, prison is a place to escape from. For South Koreans in need of a break from the demands of everyday life, a day or two in a faux jail is the escape.

“This prison gives me a sense of freedom,” says Park Hye-ri, a 28-year-old office worker who paid $90 (£70) to spend 24 hours locked up in a mock prison.

Since 2013, the Prison Inside Me facility in northeast Hongcheon has hosted more than 2,000 inmates, many of them stressed office workers and students seeking relief from South Korea’s demanding work and academic culture.

“I was too busy,” says Park, as she sits in a 5 square metre cell. “I shouldn’t be here right now, given the work I need to do. But I decided to pause and look back at myself for a better life.”

Prison rules are strict. No talking with other inmates. No mobile phones or clocks.

Clients get a blue prison uniform, a yoga mat, tea set, a pen and notebook. They sleep on the floor. There is a small toilet inside the room, but no mirror.

The menu includes steamed sweet potato and a banana shake for dinner, and rice porridge for breakfast.

Cofounder Noh Ji-Hyang says the mock prison was inspired by her husband, a prosecutor who often put in 100 hour work weeks.

“He said he would rather go into solitary confinement for a week to take a rest and feel better,” she says. “That was the beginning.”

A downturn in South Korea’s high-tech export-driven economy has intensified a hyper-competitive school and work environment that experts say adds to a high incidence of stress and suicide.

South Koreans worked 2,024 hours on average in 2017, the third longest after Mexico and Costa Rica, in a survey of 36 member countries in the Organisation for Economic Cooperation and Development.

To help people work less and earn more, the government has raised the minimum wage and cut the legal cap on working hours to 52 per week from 68. But the policies could backfire and put at risk more jobs than they create, economists say.

Noh says some customers are wary of spending 24 or 48 hours in a prison cell, until they try it.

“After a stay in the prison, people say, ‘This is not a prison, the real prison is where we return to’,” she says.
