Plain Language Summary: Typhoon Faxai (T1915) struck the Kanto region of Japan during September 8 and 9, 2019, producing many lightning discharges. This study investigated the characteristics of the lightning activity in comparison with the internal structure of precipitation in the eyewall. The storm was highly unusual in that it produced a high percentage of positive cloud-to-ground (CG) flashes, despite appearing to be normally electrified.
