North Korea launched a suspected ballistic missile from the Wonsan area towards Japan early Wednesday, flying over 700km (435 miles) before falling into the Sea of Japan. This marks the second missile launch in less than a week, with Japan's Defense Minister Shinjiro Koizumi condemning it as a 'threat to peace and security.'234

The missile launch occurred just days before the start of the Ulchi Freedom Shield exercises, a series of joint military drills between the U.S. and South Korea aimed at enhancing defense capabilities against North Korea. The drills, which begin Monday, are seen by Pyongyang as rehearsals for invasion, prompting it to respond with missile tests.

Seoul's Joint Chiefs of Staff reported that the missile was detected around 6am local time, and the U.S. military is monitoring the situation closely, stating that the launch does not pose an immediate threat to U.S. personnel or allies. “The United States remains committed to the defense of the U.S. homeland and our allies in the region,” U.S. Pacific Command said in a statement.

Following the previous launch on August 5, which also originated from Wonsan, South Korea's military increased its surveillance and coordination with the U.S. and Japan. The South Korean presidential national security council labeled that launch a 'provocation' and urged North Korea to cease its missile activities.

As tensions rise, Japan has lodged a formal protest with North Korea through its embassy in Beijing, emphasizing the need for regional stability amidst ongoing military exercises.
