Typhoon No. 6 dumped record rainfall across Kyushu on Tuesday, triggering warnings as the storm moves toward central Japan [1].

The unprecedented precipitation threatens to cause widespread flooding and landslides in several prefectures, placing millions of residents on high alert as the system tracks toward more densely populated regions.

In the Tano district of Miyazaki City, rainfall exceeded 300 mm over a 24-hour period [1]. This amount represents a record for the month of June in Kyushu [1]. The intense moisture and strong winds associated with the typhoon's trajectory caused these extreme totals on June 2, 2026 [1].

The storm's impact was felt prior to its arrival in Kyushu. In Okinawa, the typhoon left nine people injured [2]. Additionally, six houses were reported as partially damaged in the Okinawa region [2].

Meteorologists expect the storm to continue its northward movement. Forecasts indicate the system will move south of Shikoku on the night of June 2, 2026 [1]. The storm is then expected to approach the Kanto region on June 3, 2026, with the closest approach occurring during the daytime [1].

Local authorities have issued rain warnings for the affected areas. Residents in the path of the storm are urged to monitor weather updates and prepare for potential evacuations as the system brings continued heavy rain to Honshu [1].

“Rainfall exceeded 300 mm over a 24-hour period in Miyazaki City's Tano district.”

The record-breaking rainfall in Kyushu suggests a high-intensity moisture profile that could lead to significant infrastructure damage and casualties if similar totals occur in the Kanto region, which houses a much larger population than the Tano district.
