"Kuwabara kuwabara"(桑原桑原) is a phrase used in the Japanese language to ward off lightning. It is akin to the English phrase "knock on wood" to prevent bad luck. When translated to English, kuwabara means 'mulberry field'. According to one explanation, there is a Chinese legend that mulberry trees are not struck by lightning. In contrast, Joya asserts that the "origin of kuwabara is not definitely known, but it has nothing to do with mulberry plants, though it means 'mulberry fields."
