About This Trend
梅雨前線（ばいうぜんせん）is a weather front that brings significant rain and marks the beginning of the wet season in Japan.
The reason 梅雨前線 is trending now is due to its unusual disappearance and re-emergence, with forecasts predicting its return to the Japanese Sea and potentially bringing heavy rain and heatwaves to various regions of Japan, including 北日本 and 西日本.
