The death toll from a magnitude 6.8 earthquake in Kumamoto Prefecture, on Japan's southern island of Kyushu, has risen to 35, prefectural officials said, according to public broadcaster NHK.
The 72-hour window considered most critical for survival and rescue after the earthquake closed on Friday, marking three full days since the quake struck.
Search and rescue operations are continuing across all affected sites, including the Eon Mall shopping center, where the roof and walls collapsed, and a Nippon Paper Industries plant, where a chimney came down.
Six people pulled from the rubble remain in serious condition. Around 80,000 households remain without water and 4,500 without electricity.
More than 9,000 people are currently staying at evacuation centers set up by the prefectural government. According to Japan's Ministry of Health, 53 medical facilities in the region are still without water or power following the earthquake.
The Japan Meteorological Agency said the earthquake struck the Uki and Hikawa areas of Kumamoto Prefecture, both located near Kumamoto City on Kyushu on July 28.
The magnitude 6.8 quake, recorded at a depth of 10 kilometers, caused widespread damage across the prefecture, including fires and the collapse of roads and bridges.
A magnitude 7 earthquake that struck Kumamoto Prefecture in April 2016 killed 277 people.
Japan, one of the countries at highest risk of earthquakes in the world, sits on the Pacific Ring of Fire, a belt of volcanoes and ocean trenches.
