TOKYO (Sputnik) — Earlier in the day, North Korean military announced the launch of a projectile, possibly a ballistic missile, into the Sea of Japan.
"Such provocative actions are unacceptable," Kishida said, as quoted by the Kyodo news agency.
According to Kishida, no damage to Japanese ships has been reported yet.
Tensions on the Korean Peninsula escalated after North Korea successfully carried out a hydrogen bomb test in early January and put a satellite into orbit a month later, violating UN Security Council resolutions and triggering condemnation from the international community.
Pyongyang has fired multiple rocket launchers at least thrice in March alone, according to the news agency.
