The launch early on Sunday took place at a region, named Kusong, where the North previously test-launched intermediate-range missile it is believed to be developing.
Japan said the missile flew for 30 minutes and dropped in the sea between the North's east coast and Japan.
North Korea has fired an unidentified projectile, Seoul says, and a report says the projectile appears to be a ballistic missile.
The launch, from a region near North Korea's west coast, was reported by South Korea's military, which added the nature of the projectile was unclear.
The Yonhap news agency reported the projectile appeared to be a ballistic missile, and Japan immediately protested what it said was the firing of a ballistic missile.
