State media in North Korea on Friday said the country successfully tested a "super-large rocket launcher " the day before.
The report did not say whether leader Kim Jong Un oversaw the test.
South Korea's military on Thursday said the country fired two projectiles from South Phyongan Province the same day.
Japan's government said they were short-range ballistic missiles and flew between 350 and 400 kilometers. Tokyo said the missiles fell into the Sea of Japan outside of the country's exclusive economic zone.
