This has been folk knowledge in Japan for thousands of years. Rice paddies are traditionally planted in places with a propensity to lightning storms, a fact so well known that it reduces land values in suburbs built on old paddy land (there are other downsides to that land, but this is one).
Also, the word for "thunder" (雷) is written as "rain" (雨) over a "rice paddy" (田), and the word for "lightning" (稲妻) is "rice plant's (稲) wife (妻)".
