Due to Typhoon No. 15, Shizuoka Prefecture experienced record rainfall from the night of the 23rd to the morning of the 24th, causing disasters throughout the prefecture's central and western regions. As of 6 a.m. on March 26, 1,496 buildings in Shizuoka and Hamamatsu cities were flooded above floor level, and 2,534 buildings were under floor level. Isolated villages were formed in Shizuoka City, Shimada City, and Kawanehon Town due to landslides and other factors. In Shimizu Ward, Shizuoka City, about 63,000 households are experiencing water outages due to the inability to draw water from the Okitsu River. 20 prefectural and national highways are closed to traffic. River revetments also collapsed in various places. Some bridges have collapsed, and the prefecture is rushing to ascertain the extent of the damage.
From 6:00 pm on the 23rd to 6:00 am on the 24th, the continuous rainfall was 526 mm at the Ikumi Observatory in Shimada City and 379 mm at the Kuromata Observatory in Kakegawa City. Record-breaking short-term heavy rain warnings were issued 32 times in 11 municipalities. The river has reached the flood danger water level and flood start water level, but everything is normal now. Part of the Futamatagawa Shogetsu Bridge collapsed.
A total of 20 roads, including National Route 473, National Route 362, and the Southern Alps Park Route, are completely closed to traffic. There are 19 isolated villages in Shizuoka City, 2 in Shimada City, and 4 in Kawanehon Town. Two power transmission towers of the Chubu Electric Power Grid installed in the mountains of Aoi Ward, Shizuoka City, collapsed due to the effects of the typhoon. As of 9:00 a.m. on the 26th, about 330 households were without power.
Due to the water outage in Shimizu Ward, Shizuoka City, the water intake from the Okitsu River is filled with driftwood, making it impossible to take in water. Although removal work is being carried out, full-scale restoration work using heavy machinery will start after the 27th. On the 26th, the city requested the prefecture to dispatch the Self-Defense Forces to secure drinking water. In advance of this, the Chubu Regional Development Bureau has been providing water supply support to Shizuoka City and Kawanehon Town from land and sea areas.
The civil engineering offices of Shizuoka, Shimada, Fukuroi, and Hamamatsu in the midwestern prefectures that suffered the most damage began investigating the extent of damage within their jurisdiction from the 26th. Since the full extent of the damage has not been grasped, as of noon on the 26th, the local construction industry associations have not been requested to mobilize based on the agreement, and it seems that local construction companies are responding to requests from municipalities. The Shizuoka Prefecture Construction Contractors Association has put in place an information gathering system to respond to wide-area dispatch requests.
