Japan Meteorological Agency forecaster Norihisa Fujikawa explained that warm, humid air continued to flow in from the edge of the Pacific high-pressure system and the eastern edge of a large-scale low-pressure area over the sea south of Japan, heading towards the autumn rain front that had stalled near Honshu. This is said to have increased activity on the front lines.
