A TSUNAMI warning has been issued in Japan after a 7.6 magnitude earthquake hit the country.
The Japan Meterological Agency reported a quake hitting Ishikawa located in the Chūbu region of Honshu island and nearby prefectures shortly after 4pm.
It issued a major tsunami warning for Ishikawa and lower-level tsunami warnings or advisories for the rest of the northwestern coast of the island of Honshu.
Japanese public broadcaster NHK TV warned torrents of water could reach as high as 5m (16.5ft) and urged people to flee to high land or a top of a nearby building as quickly as possible.
NHK said the tsunami waves could keep returning and warnings were continuing to be aired nearly an hour after the initial alert.
The government was set to hold a news conference later in the day.
