TOKYO (AFP)
A 6.3-magnitude earthquake struck northern Japan on Monday, the country's weather agency said, but no tsunami warning was issued.
The quake hit at 8:22 pm (1122 GMT) in Pacific waters off northern Miyagi prefecture, according to the Japan Meteorological Agency, but there were no immediate reports of any damage.
The tremor comes after a powerful 7.7 magnitude earthquake hit near the northern region in April, which prompted a tsunami alert at the time.
