Widespread flooding was reported as Typhoon No. 19 battered the nation from Oct. 12 to 13, packing record rains that caused rivers to overspill their banks in many locations including Tokyo, Shizuoka and Saitama prefectures.

The land ministry said 10 banks of nine rivers that are managed by the central government and prefectures had collapsed as of 6 a.m. on Oct. 13.

In the capital’s Setagaya Ward on the evening of Oct. 12, the Tamagawa river overflowed its banks and flooded surrounding residential areas and roads.

The Chikumagawa river overran its banks in Nagano and Ueda, both located in Nagano Prefecture, as did the Ushibuchigawa river in Kikugawa, Shizuoka Prefecture, and the Tokigawa river in Higashi-Matsuyama, Saitama Prefecture.

According to the land ministry's Hokuriku Regional Development Bureau, the water level of the Chikumagawa river rose and the riverbanks began collapsing at around 2:15 a.m. on Oct. 13.

Toward the early morning, the banks were washed away, allowing the turbid waters to flow into the Hoyasu district of Nagano extensively. The first floor of many houses there were flooded, and residents were seen on the roofs and verandas waving for help.

The ministry officials said the collapsed portions of the banks is massive and expected the damage to become more widespread.

In Miyagi Prefecture, the Abukumagawa river that runs through Marumori, a town in the southern part of the prefecture, as well as its tributaries, have overspilled their banks.

The prefectural headquarters for disaster control reported that floodwaters gushed into buildings on a large scale, leaving many districts in the town isolated.

Flooded roads and mudslides have also been observed in the surrounding area.

The town government’s office escaped the flood, but land-line telephones have been inoperable due to power outages in the town. About 3,300 houses in the town have experienced a water stoppage from the night of Oct. 12.

Self-Defense Forces’ personnel and firefighters have conducted rescue operations.

In Mizunuma district of Ishinomaki, Miyagi Prefecture, a man in his 60s has been missing since at around 9 p.m. on Oct. 12.

According to the city’s crisis measures division, the man was patrolling the neighborhood along with a few other residents to check for fallen trees on roads. The man was walking in the back of the line, when others noticed he was missing. The man is believed to have slipped and fallen into a nearby stream.

According to the prefectural police, one person in Marumori suffered cardiopulmonary arrest and was transported to a hospital.
