GPM measured rain falling in Etau at a rate of up
to 88.0 mm (3.5 inches) per hour in some areas. The same powerful storms
reached heights of almost 16 km (9.9 miles).

This was not a Super Typhoon, it wasn't even a Typhoon, it was a Tropical Storm and caused more damage than most fast moving storms would cause.
...ON September 7 at 1416 UTC (10:16 a.m. EDT), (click here) Tropical Storm Etau was
drenching Japan with intense rainfall as it moved northward over the
main island of Honshu. Rainfall amounts of over 300 mm (almost 12
inches) have been reported. GPM made measurements of rainfall and storm
top heights in Etau when the satellite passed over the center of the
tropical storm. GPM's Microwave Imager (GMI) and Dual-Frequency
Precipitation Radar (DPR) measured rain falling at a rate of up to 88.0
mm (3.5 inches) per hour in some areas. The same powerful storms that
were dropping heavy rainfall were also shown by GPM radar (Ku Band) to
reach heights of almost 16 km (9.9 miles).
On Sept. 8 at 16:41 UTC (12:41 p.m. EDT), the AIRS or Atmospheric Infrared Sounder instrument aboard NASA's Aqua satellite provided an infrared look at Etau land falling in east central Japan. The strongest storms with coldest cloud tops were over the Kansai and Hokkaido regions at the time Aqua flew overhead. AIRS measured cloud top temperatures near -63 Fahrenheit/-53 Celsius. NASA research indicates that storms with cloud top temperatures that cold, high in the troposphere, have the ability to generate heavy rainfall, as GPM indicated the previous day.
The final warning for Tropical Storm Etau was issued on September 9, 2015 at 0900 UTC (5 a.m. EDT). By that time, the storm had moved over Japan and emerged into the Sea of Japan, where it was becoming extra-tropical....
