Typhoon Jebi will continue to threaten lives and property as it sweeps through Japan into Wednesday.

Jebi made landfall in eastern Shikoku around midday Tuesday, local time, with the equivalent strength to that of a Category 3 hurricane. The storm then crossed through southern and central Honshu.

Nearly one million people were put under evacuation advisories as the typhoon approached, according to Reuters.

Bullet train operations have been suspended from Tokyo to Hiroshima because of Jebi, according to NHK. Nearly 600 domestic flights were canceled for Tuesday.

"Damaging winds and coastal flooding may be the most significant impacts with this storm," according to AccuWeather Senior Meteorologist Adam Douty.

Jebi Risk 9/3

Jebi, once a super typhoon, will continue to slam southern and central Honshu through Tuesday before racing toward Hokkaido Tuesday night into Wednesday.

"Highest-sustained winds at landfall can be about 145-160 km/h (90-100 mph), which will have the potential to cause significant damage," he said. "Some wind gusts near the coast could be higher than this."

The current forecast track of Jebi, which has high confidence, puts the prefectures of Kochi, Tokushima, Wakayama, Nara and Mie at risk for the most destructive winds.

Well-built homes and businesses can sustain major damage, especially to roofs. Many trees can be snapped or uprooted, which can further damage property. Widespread power outages and water shortages can last for several days or weeks in the areas hit hardest by Jebi's destructive winds.

Downed trees and power lines can block roads, significantly delaying storm cleanup and recovery.

The southern coast of Japan, near and east of where Jebi slams onshore, can also face life-threatening storm surge flooding.

The quick movement of Jebi may limit major flooding, but flash flooding and mudslides are still concerns in the mountains of central Honshu where an AccuWeather Local StormMax™ of 400 mm (16 inches) of rain is anticipated.

Damaging winds, widespread tree damage, prolonged power outages and flash flooding may not be confined to areas near Jebi's landfall.

"Outside of where Jebi moves inland, wind gusts of 95-130 km/h (60-80 mph) may be more common across central Honshu," according to Douty.

Gusts in the lower end of this range may also be seen in Tokyo, even if the city escapes the heaviest rainfall.

Windows of skyscrapers can get knocked out with the falling glass creating more hazards for people on the city streets below. Based on the latest projected path, the worst conditions in Tokyo will occur into Tuesday night. Gusty winds and downpours will continue into Wednesday, impacting the morning commute.

"Jebi should weaken while tracking across Japan into Wednesday, though it can still be a typhoon during much of its path," Douty said.

Douty warns of isolated wind damage and localized flooding across northern Honshu and western Hokkaido Tuesday night into Wednesday. Seas will also become dangerous around these areas.

"By Wednesday, Jebi is expected to curve into far southeastern Russia and eventually dissipate during the second half of the week," Douty said.

Destruction caused by Jebi would further put a strain on Japan’s disaster recovery budget. Japan has already been hit hard by other tropical systems, historic flooding and a deadly heat wave this year.

"Jebi will be the seventh named storm to impact Japan this year and comes on the heels of Cimaron, which slammed into Japan less than two weeks ago," according to AccuWeather Senior Meteorologist Jason Nicholls.
