This paper focuses on upward negative flashes initiated from the top of the tower observed in April 2017. Of the 3 confirmed upward flashes, all current waveforms were recorded by Rogowski coils installed on the tower at a height of 497 m. One out of 3 upward flashes was a positive flash initiated by a negative upward leader, and the rest were negative flashes initiated by positive upward leaders. For each event, we conducted simultaneous observations of the lightning current waveform, EM waveform, and optical images.
