Tokyo (CNN) Yet another natural disaster has struck part of Japan, continuing a summer of chaos that has seen the country weather deadly floods, typhoons, earthquakes, landslides and heatwaves.

At least 9 people were killed in Thursday's earthquake, Chief Cabinet Secretary Yoshihide Suga said Friday.

The government had previously said 16 people died, but Suga told reporters later that this figure was incorrect and officials had mistakenly also counted those who suffered heart attacks due to the quake.

Photo taken Sept. 6, 2018, from a Kyodo News airplane shows the site of a landslide in Atsuma, Hokkaido, northern Japan, triggered by an earthquake with preliminary magnitude of 6.7 that struck the region.

Search and rescue teams are still looking for 26 people missing in the western town of Atsuma in Hokkaido Prefecture. Prime Minister Shinzo Abe said that more than 22,000 people were involved in the rescue efforts, as the northern island still deals with the after effects of the magnitude-6.6 quake, which caused landslides that buried homes and other buildings.
