Currently, the height of wind turbines are becoming taller for higher power generation, and this may change lightning performances such as the escalation of frequency of the lightning strikes. However, there are few studies of current observations for upward lightning flashes hitting wind turbines which height are over 100m. In addition, the variation of the characteristics of upward lightning flashes currents depends on observation areas and the effect of the global warming remains unclear. Thus, the observation of upward lighting current has started at the Kashiwazaki-Kariwa power plant since 2020. This paper reports the summary of the observation system and observed data as of March 2022.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.143 No.2 （2023） 特集：令和4年電力・エネルギー部門大会本誌掲載ページ: 118-124 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/143/2/143_118/_article/-char/ja/
