A tsunami advisory was also issued for parts of Alaska and the entire West Coast after a powerful earthquake off Russia's Kamchatka Peninsula.

Japan's weather office on Thursday lifted a tsunami advisory imposed a day earlier after Russia's Far East was rocked by one of the strongest earthquakes on record.The beaching of four sperm whales on a beach in Japan was initially blamed on the earthquake but officials said the animals had washed up a day earlier.

As the Foreign Office has not warned against non-essential travel to Japan, there will be no special circumstances in place to be able to cancel a trip for a full refund. The conditions for cancelling your trip will be dependent on your holiday provider, so it’s best to contact them if you’re looking to postpone.
