Typhoon 15 reached its closest point to the Tohoku and Kanto regions of Japan on July 11 [1].
The storm's approach threatens coastal infrastructure and public safety through a combination of high waves and intense precipitation. Residents in high-risk areas are being urged to monitor weather updates as the system moves across the Pacific side of the country.
Heavy rain was expected to intensify during the night in Fukushima Prefecture and the Kanto region [1]. Meteorological data indicates that the storm is moving along an atmospheric flow that pushes it westward toward Honshu [2]. While the system does not currently contain a storm-force wind zone, officials said that coastal areas remain vulnerable to strong winds and high waves [2].
Temperature forecasts accompanying the storm's movement show significant heat across other parts of the country. Nagoya was expected to reach a high of 36 degrees Celsius [1], while Tokyo was forecasted at 33 degrees Celsius [1]. Other regions remained warm, with Nagano and Kanazawa both reaching 32 degrees Celsius [1].
In the north, temperatures were more moderate. Sapporo and Aomori were both forecasted to hit 27 degrees Celsius [1], while Morioka and Sendai were expected to reach 28 degrees Celsius [1]. Kushiro was forecasted at 24 degrees Celsius [1], and Niigata at 30 degrees Celsius [1].
"Typhoon 15 will be closest to Kanto tomorrow. Please be careful of strong winds and high waves, especially along the coast," said MSN Japan [2].
TBS NEWS DIG said the storm would be closest to the Tohoku and Kanto regions on the 11th, with rain strengthening in Kanto and Fukushima that night [1]. The system is expected to transition into a tropical depression as it continues its westward path across the main island [2].
“Typhoon 15 reached its closest point to the Tohoku and Kanto regions of Japan on July 11.”
The transition of Typhoon 15 into a tropical depression suggests a decrease in peak wind intensity, but the continued movement of moist maritime air ensures that heavy rainfall remains the primary risk for the Kanto and Tohoku regions. This pattern underscores the persistent challenge of managing summer storm surges and flash flooding in Japan's densely populated coastal corridors.
