In a post on social media the Japanese PM has warned of further damage caused after the tsunami.

Sanae Takaichi said:”Even after the tsunami arrives, the second and third waves may become larger and reach the area, so please pay close attention to tsunami information and do not leave safe locations until the warning is lifted.”

She added: “Everyone in the central Hokkaido Pacific coastal area, the Aomori Prefecture Pacific coastal area, and Iwate Prefecture where a tsunami warning has been issued, please evacuate immediately to safe locations such as high ground or evacuation buildings.”
