900mm Deluge in Miyazaki Prefecture and Others
Typhoon No. 7 'Ran' Landfall on the 15th, Damage Concerns

Typhoon Khanun has passed through Kyushu and the western regions of Japan, where heavy rain damage is expected to continue. Due to the typhoon's aftermath, a rainband formed in the hinterland is expected to pour more than 300 millimeters (mm) of rain per hour, raising concerns about the spread of damage such as flooding and landslides. Additionally, Typhoon Lan, the 7th typhoon, is expected to make landfall on the main island around the 15th via the eastern coastal area, with consecutive typhoon damages anticipated.

According to NHK on the 10th, Typhoon Khanun, the 6th typhoon, moved northward through the Kyushu region early that morning and crossed into the Korean Peninsula waters. However, due to growing concerns over subsequent heavy rain damage, evacuation orders were issued to 680,000 households and 1.33 million people in Kagoshima, Miyazaki, Nagasaki, Kumamoto Prefectures, and other areas in Kyushu, with the highest alert level, Level 5 emergency safety securing orders, also issued.

As the typhoon passed, Kyushu experienced strong winds with maximum speeds of 30 meters per second, and 250 to 300 mm of torrential rain fell over Shikoku and Kyushu within a day. Some areas in Miyazaki Prefecture recorded over 980 mm of heavy rain from the 1st to that day. Flights, Shinkansen trains, and ship operations passing through Kyushu were partially suspended.

Even after the typhoon left Kyushu, a massive linear rain cloud band, known as a rainband, continues to rage, causing persistent heavy rain mainly in the southwestern regions such as Miyazaki, Oita, Ehime, and Kochi Prefectures, raising concerns about ongoing heavy rain damage.

So far, no deaths have been reported due to Khanun, but 14 injuries occurred in the Kyushu region, along with widespread power outages and water supply disruptions. In Sasebo, Nagasaki Prefecture, power was cut off to 2,300 households, and about 890 households experienced power outages in Miyazaki Prefecture. In Kagoshima Prefecture, water supply was cut off to 10,780 households, with water outage damages also being reported consecutively.

While rainband damage continues, Typhoon Lan, the 7th typhoon, is moving northward toward the Tokyo coastal area, raising concerns about additional damage. According to the Japan Meteorological Agency, Typhoon Lan is currently approaching the Ogasawara Islands in southeastern Japan, with landfall expected on the 12th. The Japanese mainland will enter the typhoon's influence zone from the 14th, and the entire eastern and central regions of Japan are expected to be affected on the 15th.

Currently, Typhoon Lan is a strong typhoon with a central pressure of 980 hectopascals (hPa) and maximum instantaneous wind speeds of 40 meters per second, moving northward. The Ogasawara Islands area is expected to receive heavy rain exceeding 200 mm per hour starting from the 12th.
