Typhoon No. 6 is approaching the mainland of Kagoshima, placing the entire prefecture within a strong-wind zone.
The storm's proximity threatens the region with severe infrastructure damage and life-threatening conditions, specifically through landslides and high waves. Local authorities have issued urgent warnings for residents to remain vigilant as the system moves northward.
In the Amami Islands, the storm's impact has already been felt through significant utility failures. Approximately 25,000 households in the islands have lost power [2].
Wind speeds have reached critical levels across the region. In Koniya, on Amami Oshima, the maximum instantaneous wind speed was recorded at 34.4 m/s [2]. Meanwhile, Yakushima recorded a maximum instantaneous wind speed of 29.8 m/s [2].
Heavy rainfall has also become a primary concern for the prefecture. In Kimotsuki Town, the 24-hour rainfall reached 226.5 mm [1]. This volume of water increases the risk of soil instability, and flash flooding in mountainous areas.
Emergency services continue to monitor the situation as the typhoon makes its closest approach to the mainland. Residents in Shibushi City and Kimotsuki Town are among those facing the highest risks from the storm's current trajectory. Officials said the risk of landslides, storms, and high waves remains high.

The simultaneous occurrence of extreme wind speeds and heavy rainfall in Kagoshima increases the likelihood of compound disasters, where power outages hinder emergency response to landslide victims. The scale of the blackouts in the Amami Islands suggests significant damage to the electrical grid that may take considerable time to repair given the ongoing storm conditions.
