The 1993 Japanese rainy season was longer than usual, as a high pressure area in the Pacific Ocean was weak, marking a cold summer.
The Japan Meteorological Agency had earlier declared the end of the rainy season only to cancel it.
The total rain amounted to 1000 mm in southern Kyushu, causing landslides or floods.
[1] National Highway No.10, Kyushu Expressway Motorway and Japan Railway railroads were completely out of service.
In the Ryugamizu area, where mountains were close to the sea, and highways and railroads are situated, 22 debris flows occurred and 2500 people were trapped in 1200 cars, as well as buses and trains, until they were saved by fishing boats and ferrys which carried them to Kagoshima city through Kagoshima Bay.
