But most of the storm’s punch had been lost before it made landfall on the country’s main island of Honshu.
Flash flooding prompted officials to recommend nearly 50,000 households evacuate from low-lying areas.
As much as 20 inches of rain fell in some of the worst-affected areas.
While technically only a tropical storm during its time over Honshu, Guchol still mustered up wind gusts of nearly 80 mph as it passed near Tokyo before dawn on Tuesday.
It became the first tropical storm to make a landfall on Japan this year, and the first since 2004 to do so as early as June.
Typhoon Talim, the fifth typhoon of the season located in the South China Sea, was expected to dump even more rainfall over the Japanese archipelago only three days after the passage of Guchol.
Guchol means "turmeric" in a Micronesian language.
