SEOUL, South Korea — North Korea will temporarily suspend its epic mass gymnastics show, a rare foreign tourist attraction in the isolated country, after the propaganda-filled festival was panned by the North’s leader, Kim Jong-un, travel agencies said on Wednesday.

Mr. Kim, along with his wife, Ri Sol-ju, and his sister Kim Yo-jong, watched the show, called “The Land of the People,” at its premiere on Monday at the cavernous May Day Stadium in Pyongyang, the capital. But the show’s fate was quickly thrown into doubt when Mr. Kim expressed serious displeasure.

The mass games performances, which North Korea has staged on and off for years under different names, typically feature thousands of schoolchildren and other youthful performers making synchronized moves in what is widely regarded as the biggest and most spectacular entertainment for North Korean elites.
