The direction of the missile, so close to Russian Federation, was likely an attempt by North Korean leader Kim Jong Un to send a message to both Moscow and Beijing, said Carl Schuster, a Hawaii Pacific University professor and former director of operations at the US Pacific Command's Joint Intelligence Center.
Japan's Prime Minister Shinzo Abe said he and South Korean President Moon Jae-in discussed by phone North Korea's latest missile test, while his top national security adviser also spoke with his US counterpart.
Chief Japanese Cabinet Secretary, Yoshihide Suga, called the latest test a violation of United Nations resolutions as he and Prime Minister Shinzo Abe condemned the move and issued a strong protest over North Korea's actions.
"North Korea has been a flagrant menace for far too long". Japan's Kyodo News agency, citing unidentified sources, said the missile may be capable of covering a range as far as 4,000 kilometers (2,500 miles) if launched at a normal trajectory.
Australia has condemned North Korea for its latest ballistic missile test, calling it "reckless and provocative". He added that the missile didn't come down in Japan's exclusive economic zone, waters within 322 kilometers (200 miles) of the coast for which it has jurisdiction over resources.
The missile was sacked from the region of Kusong, northwest of Pyongyang, where the North in February successfully test-launched an intermediate-range missile that it is believed to be developing.
"The president said we are leaving open the possibility of dialogue with North Korea, but we should sternly deal with a provocation to prevent North Korea from miscalculating".
"North Korea wants to attain a credible regional nuclear capability with which it can hold regional targets under nuclear threat", he said.
The United States called for repercussions from the global community.
"The timing is not coincidental", Schuster said, adding that Kim may be trying to get Putin more involved on the situation on the Korean Peninsula.
That missile, launched April 29, blew up over land in North Korean territory, according to a spokesman for the US Pacific Command.
Kishida says he and South Korean Foreign Minister Yun Byung-se shared the view that dialogue is important for resolving the North Korean tensions.
The White House said the US maintains its "ironclad commitment" to stand with its allies in the face of the serious threat posed by North Korea, and added that the latest "provocation" should serve as a call for all nations to implement far stronger sanctions against the North.
Moon won Tuesday's election on a platform of a moderate approach to North Korea and has said he would be willing to go to Pyongyang under the right circumstances, arguing dialogue must be used in parallel with sanctions.
The missile flew for half an hour and reached an unusually high altitude before landing in the Sea of Japan, the South Korean, Japanese and USA militaries said. Trump has also said he'd be "honored" to talk with leader Kim Jong Un under favorable conditions.
The latest test - the seventh this year - came a day after senior North Korean official Choi Sun-hee said her government would be willing to start talks with the USA "if the conditions are set".
Japanese officials said the missile flew for about 30 minutes, traveling about 800 kilometers (500 miles) and reaching an unusually high altitude of 2,000 kilometers (1,240 miles).
The missile impacted "so close to Russian soil - in fact, closer to Russia than to Japan - the President can not imagine that Russia is pleased", the White House said.
Japan Chief Cabinet Secretary Yoshihide Suga declined to comment when he was asked whether the latest missile launch was a success, and whether it represented a new level of threat.
Multiple sets of United Nations and USA sanctions against North Korea have done little to deter Pyongyang from pursuing its nuclear and missile ambitions.
Prime Minister Shinzo Abe told reporters Sunday that the launch is "absolutely unacceptable" and that Japan will respond resolutely.
On Saturday, a top North Korean diplomat in charge of USA relations, Choe Son Hui, told reporters in Beijing that Pyongyang would be willing to meet with the Trump administration for negotiations "if the conditions are set".
