In comments to The Associated Press, Vice Minister Han Song Ryol said the USA was becoming "more vicious and more aggressive" under Trump and warned the president against provoking North Korea.
"The security situation around our country is getting increasingly severe", Abe said, who was addressing the Japanese parliament's diplomacy and defense committee.
"There is a possibility that North Korea already has a capability to deliver missiles with sarin as warheads", Abe said in front of Parliament Thursday. As it prepares for the 105th anniversary of the birth of its founder Kim Il Sung on Saturday, North Korean has intensified its rhetoric, warning of strong retaliation against any aggression as U.S.
Abe said that "tension is certainly rising" and that Tokyo needs to strengthen their defences.
China has becoming increasingly vocal about North Korea's missile and nuclear threats, and state media editorials have begun to address Pyongyang directly with regards to a possible solution.
Japan's National Security Council discussed how to evacuate its almost 60,000 citizens from South Korea in the event of a crisis, a government official said on Friday, amid rising concern over North Korea's nuclear weapons program. Leaders have in the past used the date to carry out weapons tests.
As tensions grew to a fever pitch elsewhere over the likelihood of North Korea conducting a nuclear or long-range missile test, possibly this weekend, there was little sign of concern in South Korea's capital, Seoul, which lies within range of the North's artillery.
USA soldiers prepare for a military exercise near the border between South and North Korea on April 14, 2017 in Paju, South Korea.
In 2015, the Pentagon told Congress North Korea "likely possesses a CW stockpile" and likely had "the capability to produce nerve, blister, blood, and choking agents". The military also plans to introduce or obtain new guided bombs, Hyunmoo-2 ballistic missiles, Hyunmoo-3 cruise missiles, and Taurus air-to-ground missiles to strike against North Korean nuclear and missile facilities.
The sprawling development project, built in just over a year, includes Pyongyang's tallest apartments, at 70 stories.
