Buddhism-based meditation tours are quite popular in Korea. Many Korean temples offers "Temple stay" [1] program which is pretty much the same as the jail: locking themselves up in the temple to escape from the city life for a cople of days. The jail in the article seems to be a slightly exaggerated form of templestay. The motivation behind it is pretty accurate tho.

Of course not everyone want this, and it is Buddhism - half of Koreans are christian.

In America, there are Catholic retreats, some at retreat centers, some at monasteries or convents, some elsewhere; I assume that other Christian denominations have retreats, but don't know and have never enquired.

For that matter, the writer Patrick Leigh Fermor, who was not Catholic, wrote about going to stay for a short period at the Benedictine abbey of St. Wandrille, mostly to get away from distractions. You can find the account in https://www.nyrb.com/products/a-time-to-keep-silence.
