The country's central news agency said it would blow up all the tunnels on the nuclear test ground.
The Democratic People's Republic of Korea (DPRK) announced that it will hold a ceremony for the dismantling of its nuclear test site on May 23-25, state media said Saturday.
During the third inter-Korean summit on April 27, Kim told South Korean President Moon Jae-in that he would "carry out the closure of the northern nuclear test site in May", according to Seoul's presidential office, Cheong Wa Dae.
The isolated Asian nation, which had already pledged to begin dismantling the site this month, will invite journalists from China, Russia, the US, the United Kingdom and South Korea to cover the event, KCNA said in the statement.
"All global journalists will be provided with (a) charter flight from Beijing to Wonsan", it said.
Tensions had been mounting for years as Pyongyang's nuclear weapons and ballistic missile programmes saw it subjected to multiple rounds of increasingly strict sanctions by the UN Security Council, the US, EU, South Korea and others, and Trump last year threatened the North with "fire and fury".
The test tunnels would be blown up, blocking their entries, the statement said.

He later called off the demonstrations after the ruling party assured him of its support in his bid for prime minister. Lawmakers voted 59 to 42 to approve him as prime minister.
During their summit at a border truce village, Moon and Kim vaguely promised to work toward the "complete denuclearization" of the Korean Peninsula, but made no references to verification or timetables.
But sceptics warn that Pyongyang has yet to make any public commitment to give up its arsenal, which includes missiles capable of reaching the United States. However, a final attempt by Bush to complete an agreement to fully dismantle North Korea's nuclear weapons program collapsed that December when the North refused to accept USA -proposed verification methods.
Kim declared his nuclear force as complete in December, following North Korea's most powerful nuclear test to date in September and three flight tests of ICBMs created to reach the US mainland.
Following the release of three American prisoners Wednesday, President Donald Trump announced he will meet with Kim in Singapore on June 12.
"The North will shut down a nuclear test site in the country's northern side to prove the vow to suspend nuclear test".
Not only was it later revealed North Korea was secretly enriching uranium, but the rogue nation conducted its second nuclear test less than one year later in May 2009.
