(CNN) — North Korea launched a suspected intercontinental ballistic missile (ICBM) on Friday, the second missile test by the Kim Jong Un regime in two days, in actions condemned as unacceptable by Japanese Prime Minister Fumio Kishida.

The presumed ICBM was launched around 10:15 a.m. local time from the Sunan area of the North Korean capital Pyongyang, South Korea’s Joint Chiefs of Staff (JCS) said.

Kishida said it likely fell in Japan’s exclusive economic zone (EEZ), about 210 kilometers (130 miles) west of the Japanese island of Oshima Oshima, according to the Japan Coast Guard. It did not fly over Japan.

“North Korea is continuing to carry out provocative actions at frequency never seen before,” Kishida told reporters Friday at the Asia-Pacific Economic Cooperation (APEC) meeting in Bangkok, Thailand.

“I want to restate that we cannot accept such actions,” he said.

The Japanese government will continue to collect and analyze information and provide prompt updates to the public, he said. So far, there have been no reports of damage to vessels at sea, Kishida added.

The Misawa Air Base issued a shelter in place alert after the firing of the missile, according to US Air Force Col. Greg Hignite, director of public affairs for US Forces Japan. It has now been lifted and the US military is still analyzing the flight path, he said.

The launch comes one day after Pyongyang fired a short-range ballistic missile into the waters off the east coast of the Korean Peninsula, and issued a stern warning to the United States of a “fiercer military counteraction” to its tighter defense ties with South Korea and Japan.

It’s the second suspected test launch of an ICBM this month — an earlier missile fired on November 3 appeared to have failed, a South Korean government source told CNN at the time.

Increased missile tests

The aggressive acceleration in weapons testing and rhetoric has sparked alarm in the region, with the US, South Korea and Japan responding with missile launches and joint military exercises.

Leif-Eric Easley, associate professor of International Studies at Ewha Womans University in Seoul, said North Korea is “trying to disrupt international cooperation against it by escalating military tensions and suggesting it has the capability of holding American cities at risk of nuclear attack.”

North Korea has carried out missile tests on 34 days this year, sometimes firing multiple missiles in a single day, according to a CNN count. The tally includes both cruise and ballistic missiles, with the latter making up the majority of North Korean test this year.

There are substantial differences between these two types of missiles.

A ballistic missile is launched with a rocket and travels outside Earth’s atmosphere, gliding in space before it re-enters the atmosphere and descends, powered only by gravity to its target.

A cruise missile is powered by a jet engine, stays inside Earth’s atmosphere during its flight and is maneuverable with control surfaces similar to an airplane’s.

Ankit Panda, senior fellow in the Nuclear Policy Program at the Carnegie Endowment for International Peace, said that while he wouldn’t see Friday’s presumed ICBM launch “as a message, per se,” it can be viewed as part of North Korea’s “process of developing capabilities Kim has identified as essential for the modernization of their nuclear forces.”

The US and international observers have been warning for months that North Korea appears to be preparing for an underground nuclear test, with satellite imagery showing activity at the nuclear test site. Such a test would be the hermit nation’s first in five years.
