Typhoon Lan was a powerful tropical cyclone that struck central Japan in mid-August 2023. The seventh named storm and fifth typhoon of the 2023 Pacific typhoon season, Lan originated from an area of low pressure several hundred kilometers east of Iwo Jima. It initially tracked north-northwestward, gradually intensifying into a tropical storm and later to typhoon status, reaching its peak as a Category 4-equivalent typhoon with sustained winds of 215 km/h (130 mph) and a central pressure of 940 hPa (27.76 inHg). Lan then quickly weakened the following day due to the effects of inner ring of cloud tops and well-defined eyewall. Lan re-strengthened again to 155 km/h (100 mph), Lan made landfall near Cape Shionomisaki in Japan. Once inland, Lan rapidly weakened and degenerated into a tropical storm over the region's rough terrain. Lan emerged back over the southern Sea of Japan, before declared it an extratropical low on August 17. The low moved east-northeast and was last noted on the next day.
Lan caused widespread damage. In addition to causing landslides and flooding, the storm also uprooted trees and damaged electrical lines. At least 100,000 homes are without power, and more than 237,000 individuals have been forced from their homes. The Japan Meteorological Agency (JMA) issued purple heavy rain—the second highest level on a four-tier scale—and landslide warnings for parts of Kyoto Prefecture in Kansai region and Iwate Prefecture in Tōhoku region as of late August 14. One person has been reported dead and 64 are reported to have remained injured following the typhoon. Total losses are estimated to be around $500 million (2023 USD) according to AON.
