At least four people have died and six others remain missing after Typhoon Dujuan unleashed record-breaking rainfall across eastern Japan, triggering landslides, flooding and widespread disruptions across the greater Tokyo region, Japanese authorities said Tuesday.

The powerful storm, the 25th typhoon of the season, moved northeastward away from Japan on Tuesday after sweeping along the country's Pacific coast. Although most heavy-rain and landslide warnings were lifted or downgraded as the storm moved offshore, authorities warned that saturated ground and swollen rivers continued to pose risks.

At least 22 people were injured, while more than 45,000 households remained without electricity, according to updated reports. More than 460 buildings were also reported damaged.

In Yokosuka, Kanagawa Prefecture, a woman in her 60s was found dead after a landslide sent mud and debris into her home. Rescue workers recovered her from the damaged building, but she was pronounced dead at the scene.

Several other people remained missing in Kanagawa after landslides struck homes in Yokosuka and nearby Miura. A couple in their 70s in Yokosuka were reported missing, while two women in Miura were also unaccounted for after mud and debris entered residential buildings. Search-and-rescue teams continued working through the debris with the assistance of police, firefighters and Self-Defense Forces personnel.

Three deaths were reported in Chiba Prefecture. Among them was a 51-year-old worker who died after heavy machinery he was operating fell into a bamboo grove while he was helping clear mud and debris from a road in Sodegaura. Authorities were investigating the circumstances surrounding the incident.

Two elderly women were also killed after landslides caused their homes to collapse, one in Kamogawa and another in Sanmu. Two men remained missing in Kamogawa, according to reports.

Dujuan dumped extraordinary amounts of rain on parts of eastern Japan.

Oshima in the Izu Islands recorded 832 millimeters of rain over 48 hours, more than twice the island's average rainfall for the entire month of September. Tokyo's Edogawa Ward also recorded a record 282.5 millimeters in 24 hours.

Other locations across the Kanto region also experienced exceptional rainfall, with some areas recording their highest totals since observations began. The intense downpours saturated hillsides and caused rivers to rise rapidly, increasing the danger of further flooding and landslides.

The Japan Meteorological Agency had issued its highest-level landslide special warning on Monday for parts of the Izu Islands, including Oshima, as Dujuan approached.

The storm prompted evacuation advisories affecting more than 1.6 million people in and around Tokyo, while nearly 1.9 million people were reportedly covered by evacuation orders or advisories at the height of the emergency.

Heavy rainfall flooded roads and disrupted railway services across Chiba and Kanagawa. Several railway lines were suspended or delayed, while flights were also affected. Japan Airlines canceled 135 flights and All Nippon Airways canceled 140 flights as the storm approached.

The storm also forced the early closure of the Tokyo Game Show, one of the world's largest video-game trade fairs, while other outdoor events were canceled or disrupted.

Tokyo Electric Power Company reported that tens of thousands of households remained without electricity after the storm. Updated figures put the number of affected households at more than 45,000 on Tuesday.

Emergency crews were working to clear fallen trees, mud and debris from roads while rescuers continued searching for missing people.

Although Dujuan had weakened and moved away from the Japanese mainland, authorities continued to warn residents in affected areas to remain cautious because the exceptionally heavy rainfall had left slopes unstable and rivers swollen.

The storm comes amid a year marked by repeated episodes of extreme rainfall, flooding and tropical storms in several parts of the world. Scientists have warned that a warmer atmosphere can hold more moisture, increasing the potential for exceptionally heavy rainfall, although the contribution of climate change to any individual storm requires separate scientific attribution. (ILKHA)
