An explosion at a restaurant in northern Japan injured 42 people late Sunday, police said, with the blast reportedly causing surrounding buildings to collapse.

Fires broke out following the incident in the northern city of Sapporo, Kyodo news agency said, and images from the scene showed large flames and plumes of smoke rising in the night air.

A police official for the Hokkaido region told AFP "there are 42 injuries" but no one was killed.

They are still investigating the cause which "would take some time".
