Why It Matters
Affected by the autumn rain front, the Kanto region has experienced continuous heavy rainfall since the 6th, and the cumulative rainfall in many places has broken historical records.
Affected by autumn rain fronts and other factors, the Kanto region of Japan has experienced record heavy rains since the 6th. Schools in many places have been suspended and railways have been suspended. The 24-hour cumulative rainfall in Niijima Village in Tokyo has exceeded 381 mm, rewriting local historical records. The Meteorological Agency urgently issued the highest level 5 "Special Earthslide Warning". NHK also urgently called on residents in dangerous areas to implement vertical evacuation, "Please sleep above the second floor tonight." This wave of disastrous rain is likely to continue until around the 10th.
Based on Japanese media reports, the Japan Meteorological Agency pointed out that thunderstorms or local heavy rains of 60 millimeters per hour may occur in the Kanto region before noon today (7th), and may even form "linear rainbands." It is estimated that as of 18:00 today, the accumulated rainfall in the Koshinobu area of Kanto in 24 hours will reach up to 250 millimeters, and the rain will continue until the day after tomorrow (8th to 9th).
As of early this morning, the 24-hour rainfall in Niijima Village, Tokyo, has exceeded 381 millimeters, setting a new local observation record. Officials have issued the highest level "black level 5 soil and sand disaster special warning"; Tokyo, Kanagawa Prefecture and Chiba Prefecture have also issued special level 4 soil and sand disaster warnings.
Kita Ward in Tokyo also issued Level 4 evacuation instructions for 2,982 households and about 5,200 residents in the soil and sand disaster warning area. In addition, Oshima Town on the Izu Islands, as well as some areas in Kanagawa and Chiba Prefectures have also successively issued evacuation instructions, and emergency shelters have been opened in various places. In order to avoid the danger of heavy rain during commuting hours, all public primary and secondary schools in Tochigi Prefecture will suspend classes today. Schools in several administrative wards of Tokyo, as well as Yokohama City and Saitama City, announced the suspension of classes.
In the face of disasters such as road flooding and swollen rivers that may be caused by heavy rainfall, Japanese officials call on the public to continue to understand the latest disaster prevention and traffic information. The NHK disaster prevention account even warned of the death cases of Typhoon 19 in 2019. Among the 21 people who died in their own homes at that time, more than half were found on the first floor of a two-story house. Therefore, if they choose to stay at home, they call on the public to "please sleep on the second floor or above tonight."
NHK also reminds that if the house is close to a hillside, it should be moved to a room above the second floor and away from the side of the hillside. At the same time, emergency kits, flashlights, mobile power supplies and other supplies should be moved upstairs. If the surrounding area is flooded, it is quite dangerous to evacuate in the dark; the best way is to move to a safe place before dark. If it is no longer safe to go out, you should immediately take indoor vertical evacuation to ensure your own safety.
