Afterwards, Jebi began a slow weakening trend as it turned northwest, briefly passing through the Philippine Area of Responsibility on September 2.

Heavy rains combined with wind and storm surge to flood over 700 houses and cause widespread damage to infrastructure, including several shrines and historical buildings.

Heavy swells produced by Jebi caused large waves along the coast of Taiwan that resulted in seven fatalities (including a suspected suicide) from September 2 to 3.

As an extratropical cyclone on September 5, Jebi produced gusty winds across the Russian Far East, causing power outages and injuring three.

A tropical disturbance was first noted by the Joint Typhoon Warning Center (JTWC) on August 26 about 1,020 km (635 mi) south-southwest of Wake Island.

[7] Further development was expected as the depression tracked northwest around a subtropical ridge, with high sea surface temperatures and low wind shear ahead in the system's anticipated path.

[7] With favorable winds aloft aiding the development of thunderstorm activity, Jebi continued to strengthen as it turned more westward under the influence of the subtropical ridge.

[11] The JMA upgraded Jebi to a severe tropical storm at 12:00 UTC on August 28 as its maximum sustained winds increased to 95 km/h (60 mph).

[5][nb 4] Amid the favorable environment, Jebi began to intensify more quickly on August 29, reaching typhoon status at 06:00 UTC as it developed an eye feature visible on microwave satellite imagery.

[21] At the same time, upper-level winds pushed subsiding air over the western part of Jebi's circulation, causing its convection to warm.

[27] Racing poleward, Jebi made landfall over southern Tokushima Prefecture at around 03:00 UTC on September 4,[28] possessing winds of around 155 km/h (100 mph).

On September 2, at Mystery Beach in Nan'ao Township, Yilan County, five people riding all-terrain vehicles were swept out to sea and drowned; at least four of the bodies were recovered.

[41] Ahead of the storm, emergency evacuation orders were issued for parts of Osaka, Hyōgo, Nara, Wakayama, and Kagawa prefectures.

Evacuation advisories were issued for Ishikawa, Fukui, Yamanashi, Nagano, Gifu, Aichi, Kyoto, Okayama, Tokushima, and Kōchi prefectures.

[53] Factories across the Kansai and Chūbu regions were closed, with notable companies affected including Daikin, Panasonic, Daihatsu, and Toyota.

A man in Osaka was blown off the second floor of a house and fell to his death; at least five more people in the eponymous prefecture were killed by falls or flying debris.

In neighboring Saitama Prefecture, an elderly man in Kawagoe was injured when he was blown over by a strong gust and a woman was hit by a flying object.

Strong winds in Tochigi Prefecture caused a woman to fall and hurt her shoulder, while two others fell while attempting to repair a window on the second floor of their house.

At the nearby Nishi Hongan-ji, a UNESCO World Heritage Site, a wall on the southern face of the compound collapsed and a segment of the roof of the worship hall was peeled off.

[73] Part of the cliff on the south side of Ueda Castle collapsed, while an iron roof tile was blown off at the Katakurakan building in Suwa, Nagano.

[42][55] Kansai International Airport was forced to close on September 4, as waves reaching 5 m (16 ft) in height overtopped coastal defenses and left a runway and cargo facilities inundated.

[77][78] Access to the island was cut off on September 4 when a 2,591-tonne tanker was unmoored by Jebi's strong winds and collided with the only bridge connecting the airport to the mainland.

[85] The temporary closure of the airport—the country's third largest and a major export hub for manufacturers in the region—sparked fears that Japan's industrial production would suffer.

[86] The absence of international flights caused tourism in Osaka to decline sharply, with about a quarter of retailers reporting their sales had halved in a survey conducted by Nikkei.

[87] The damage to transport infrastructure from a combination of Jebi and other natural disasters contributed to a larger-than-expected contraction in Japan's gross domestic product for the third quarter of 2018.

A total of 30,996 hectares (76,590 acres) of cropland was damaged by the typhoon's strong winds,[89] which blew down fruit trees and caused lodging of vegetable and feed crops.

[90] At an aquaculture facility off Kushimoto, Wakayama, run by Kindai University, 600 bluefin tuna were lost after the cage containing them broke, resulting in losses of JP¥100 million (US$906,000).

[92] At the end of September, the Ministry of Agriculture, Forestry and Fisheries announced it would be providing subsidies and grants to help farmers offset repair and reconstruction costs.
