According to Seoul's Joint Chiefs of Staff (JCS), the military detected the launch from Taechon, North Pyongan Province, toward the east coast at 6:53 a.m (local time).
Japan’s Defense Minister Yasukazu Hamada also said the projectile appears to have landed outside Japan's Exclusive Economic Zone.
Coast guard authorities say there have been no reports of damage to Japanese ships.
Sunday's ballistic missile launch comes 2 days after the nuclear-powered aircraft carrier USS Ronald Reagan arrived in South Korea for a joint military exercise later this month.
This is the fifth missile launch by North Korea since South Korean President Yoon Suk-Yeol took the office in May.
