Typhoon Hagibis: Japan’s Wettest Typhoon on Record

Japan continues to assess the extent of the damage caused by Typhoon Hagibis, which made landfall near the Izu Peninsula in Shizuoka Prefecture on Saturday, October 12. Current reports state that at least 66 people have been killed, dozens of people are missing, and hundreds are injured. At this time, the worst impacted prefectures include Nagano, Saitama, Shizuoka, and Fukushima.

However, the full extent of the damage is not expected to be known for several days as rescue operations and official damage assessments continue – rescuers cannot reach some areas due to high water levels. The Japanese Prime Minister, Shinzo Abe, stated that there is no plan to slow rescue operations, with around 13,000 police, 66,000 firefighters and 31,000 Self-Defense Forces personnel involved. The numbers of structures and properties affected is predicted to rise.

Super Typhoon Hagibis: Will It Weaken by the Weekend?

As of Thursday afternoon (October 10), Super Typhoon Hagibis remains a powerful Category 4 equivalent hurricane with maximum sustained wind speeds of 150 miles per hour (240 kilometers per hour). The Japan Meteorological Agency (JMA) has described the storm as “violent” – its highest tropical cyclone classification.

Hagibis hit the headlines in recent days after it underwent one of the most rapid intensifications ever observed: its maximum sustained wind speeds intensified from 60 to 160 miles per hour in just 24 hours on October 6-7. According to media reports, only Hurricane Wilma in 2005 and Patricia in 2015, are known to have strengthened more quickly. Its peak wind speed of 160 miles per hour (258 kilometers an hour) is equivalent to a Category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Typhoon Faxai: Walking in Its Tracks

Typhoon Faxai was the strongest landfalling typhoon to impact the Greater Tokyo area since Typhoon Ma-on in 2004. Making two landfalls as it traveled across the Tokyo Bay, Faxai made a brief landfall over the Miura Peninsula, Kanagawa prefecture in the Kanto region of Japan, just 35 miles (57 kilometers) south-southwest of Tokyo early morning local time on Monday, September 9.

It then tracked northeast to make a second landfall over the city of Chiba (pop. ~979,000), Chiba prefecture, 20 miles (32 kilometers) east of Tokyo. Maximum sustained wind speeds at its landfalls were equivalent to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Just four days after, RMS reconnaissance was in Chiba prefecture, surveying the damage.

Typhoon Faxai: Strongest Typhoon to Impact Greater Tokyo in Fifteen Years

Power outages in Chiba Prefecture looked set to continue into the coming weeks as the region continues to recover from Typhoon Faxai. It was one of the strongest landfalling typhoons on record in the seven prefectures of the Kanto region surrounding Tokyo and the strongest to impact the Greater Tokyo area since Typhoon Ma-on in 2004.

Two Landfalls as Faxai Travels Across Tokyo Bay

Typhoon Faxai made a brief landfall over the Miura Peninsula, Kanagawa Prefecture in the Kanto region of Japan, just 35 miles (57 kilometers) south-southwest of Tokyo early morning local time on Monday, September 9. The center of the typhoon then tracked northeast across Tokyo Bay and made a second landfall over the city of Chiba (pop. ~979,000), Chiba Prefecture, Japan, 20 miles (32 kilometers) east of Tokyo.

According to the Japan Meteorological Agency, Faxai had maximum sustained wind speeds of 102 to 106 miles per hour (165 to 170 kilometers per hour) at its landfalls, equivalent to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale.

Twenty-Six Days: A Short Respite Between Typhoons Jebi and Trami

Typhoon Trami ravaged the southern coastline of Japan this weekend, only 26 days since Typhoon Jebi made landfall on September 4. Trami first swept through the southwest chain of Nansei Islands, and then skirted along the southern coasts of the islands of Kyushu and Shikoku, eventually making landfall over Wakayama Prefecture in the Kansai Region, during the evening of Sunday, September 30.

The southwest of Japan bore the brunt of Trami, and as of Tuesday, October 2, the Japan Fire and Disaster Management Agency (FDMA) reported a total of 2,494 buildings damaged across 32 prefectures, with 1,749 of the 2,494 damaged buildings reported as “partially damaged”, and 108 buildings “destroyed” or “partially-destroyed”. A further 637 buildings were flooded in the event. At least 195 people across 29 prefectures have been injured, with many hurt by windows shattered in high winds. 750,000 homes across Japan lost power, together with significant disruption to transport. These numbers are expected to rise as damage assessments conclude.

Four hundred miles southwest of the Japanese mainland on Okinawa Island, the largest of the Nansei Islands with a population of 1.3 million, wind gusts reached 126 miles per hour (202 kilometers per hour) at Itokazu locality in Nanjō City. Five or so miles up from Itokazu, winds topped 103 miles per hour (165 kilometers per hour) and gusts exceeded 132 miles per hour (212 kilometers per hour), at the Kadena Air Base.

Super Typhoon Jebi Follows a Long Stretch of Japanese Cat Events

This time last year, we were in the thick of a series of Atlantic hurricanes that caught the world’s attention with images of significant damage and destruction. Fast forward to 2018 and it seems that Japan is bearing the brunt of natural catastrophes this summer, with a series of typhoons, floods, and earthquakes dominating global headlines.

The latest headline maker is Super Typhoon Jebi, the fifth typhoon to impact Japan this year and billed by many media outlets as Japan’s most powerful storm in 25 years. The country’s five typhoons are just one symptom of an overall active Pacific basin, alongside a record-setting pace of tropical development in the northeast Pacific. Some outlets tie this increased Pacific activity to an El Niño phase of the El Niño Southern Oscillation (ENSO), which conversely has repressed Atlantic hurricane activity to date.

Japan: Waking Up to Flood Risk

Many factors made the recent devastating flooding and subsequent landslides and mudslides in Japan during July stand out as a defining event. From the intensity of the rainfall, the extent of the area affected and the loss of life, the sheer scale of this event was summarized by an official from the Land, Infrastructure, Transport and Tourism Ministry in Japan, who said “This is the first-time damage has extended to such a wide area since the (2011) Great East Japan Earthquake.”

As of July 16, Japan’s National Police Agency reported that 219 people had been killed, and many remain missing. Data provided on July 20 from the Fire and Disaster Management Agency (FDMA) reported damage to around 40,000 buildings across 31 prefectures, and just over half of these prefectures had 50 or more buildings damaged. Some of the worst-hit areas include Okayama, Fukuoka, Hiroshima, Ehime, Kyoto, Yamaguchi, Gifu, and Kochi.

At least 270 elementary and junior high schools were damaged; the commercial sector experienced widespread damage and destruction from landslides and rivers breaching their banks or defenses. Operations were suspended at Mazda Motor, chemicals giant Teijin and brewers Asahi Shuzo, among others, disrupting supply chains far from the disaster areas. Only 30 percent of large enterprises account for flooding in their continuity plans, according to recent Cabinet Office survey.

Overall, this event is the nation’s deadliest weather disaster since 322 people were killed in floods and landslides across western Japan in July 1982. Early estimates indicate economic losses could be higher than US$1 billion with significant impact on manufacturing and tourism. The insured losses may take some time to develop. What caused this event to happen?
