"Four Islands of the Japanese archipelago needs to drown in a sea of nuclear bomb Juche", the statement reads.
The 38 North website in the U.S., which keeps satellite watch on North Korea, raised its estimate for the yield from the explosion to around 250 kilotons - more than 16 times the size of the device that devastated Hiroshima in 1945.
The menacing comments come at the end of a few tense weeks.
Though he was not supportive of deploying or pursuing nuclear weapons, Moon said South Korea "needs to develop our military capabilities in the face of North Korea's nuclear advancement".
North Korea carried out its sixth and most powerful nuclear test on September 3, worsening already fraught U.S.
However few expect these measures to be vigorously enforced as the Kim Jong Un government has become adept over the years in evading sanctions, and North Korea's trading partners, especially China and Russian Federation, have been complicit in permitting illicit transactions to continue despite official support for sanctions. The administration of President Donald Trump has indicated it will consider secondary sanctions if the United Nations sanctions are not fully implemented. "Those sanctions are nothing compared to what ultimately will have to happen", the president remarked alongside Malaysian Prime Minister Najib Abdul Razak.

U.S. Defense Secretary James Mattis said Wednesday that he's become convinced that the United States must keep all three parts of its nuclear force, rather than eliminate one, as he once suggested. But now it likely can.
As North Korea holds more frequent and more powerful tests, the South in particular has ramped up its deterrence efforts.
While Moon was voted into office in May largely on his economic and anti-corruption policies, his first months in power have been dominated by North Korea's provocations.
That helps explain why the Trump administration feels the North Korean threat is so urgent.
"Diplomacy, we will not give up on".
Meanwhile, South Korea said it found a small amount of radioactivity in air samples collected days after the North's test. Pyongyang is already pointing thousands of pieces of artillery at Seoul, South Korea's capital - with a whopping 25.6 million residents living in the greater metropolitan area.
"They stressed the importance of holding accountable all parties that have supported North Korea's nuclear and missile programmes", it said.
Seoul apparently notified Tokyo, Washington and others of its deliberations.
