In late July, Typhoon 12 approached Taiwan, triggering sea-storm warnings and heavy rain forecasts for Hualien, Taitung, and the Hengchun Peninsula. By August, Japan experienced record-breaking rainfall in Niigata, Iwate, and Toyama prefectures, alongside high temperatures and several tropical systems, including Typhoon 13 affecting Okinawa and Amami.

On August 9, Typhoon 15 (Chan-hong) was moving slowly northwest toward eastern Japan, while Typhoon 16 (Peipao) formed near the Ogasawara Islands and Typhoon 13 (Dolphin) moved toward central China. Authorities in Japan issued urgent alerts, including a Level 4 landslide danger warning for Kitashiobara Village.

By August 8, as Typhoon 15 approached, the Japanese government established an information coordination room within the Crisis Management Center. Prime Minister Sanae Takaichi appealed for public caution, urging citizens to prepare for potential evacuations. Forecasts indicate Typhoon 15 may make landfall in the Kanto or Tohoku regions on August 11 or 12. Specific regional concerns include significant rainfall in Tokyo, potential storm surges in northern Kyoto and Hyogo prefectures, and rough seas along the Pacific coast of Tohoku. The agricultural sector has also been placed on high alert to protect crops and livestock from flooding and wind damage.
