Typhoon 15 is expected to make landfall in the Kanto and Tohoku regions on Aug. 11 [1].
The timing of the storm is critical as it coincides with the Obon holiday, one of Japan's busiest travel periods. Disruptions to transportation and safety risks for millions of travelers are expected if the storm hits as predicted.
Meteorologists have noted an unusual trajectory for the storm. While some reports indicate the system is moving east toward the Tokai and Kanto regions [3], other data suggests the typhoon is moving west in an irregular pattern [1]. This shift in direction is attributed to a cold vortex causing significant deviations in the storm's path [4].
The region is currently experiencing high instability, with three typhoons swirling in the surrounding area [1]. This complex atmospheric environment has contributed to the unpredictable movement of Typhoon 15.
Records indicate the storm has already interacted with the Japanese coastline. It previously made a second landfall in northern Wakayama Prefecture at approximately nine a.m. on Aug. 5 [2, 3].
The current forecast suggests the storm will move from Tohoku toward the Kanto region [1]. Residents in these areas are advised to monitor weather updates as the system approaches the coast tomorrow.

The erratic movement of Typhoon 15, characterized by a rare westward 'reverse' path, highlights the volatility of the current Pacific typhoon season. Because the storm is interacting with a cold vortex and other nearby tropical systems, traditional tracking models are less reliable, increasing the risk of unexpected landfall locations during a peak domestic travel window.
