North Korea has ratcheted up the tension in its nuclear stand-off with the US, firing a ballistic missile which flew over Japan before landing in the Pacific Ocean, 2,000 kilometres to the east of the country.
"These repeated provocations on the part of North Korea are not permissible and we protest in the strongest words," Japan Chief Cabinet Secretary Yoshihide Suga said.
The missile was launched at 6:57am Japan time (7:57am AEST) and splashed down at 7:16 am (8:16am AEST), some 2,000 kilometres east of the northern island's Cape Erimo, Mr Suga said.
US Secretary of State Rex Tillerson urged China and Russia to take direct action against North Korea in response to its latest missile launch.
