Tropical Storm Nari Makes Landfall on Japan's Hokkaido Island
Typhoon Nari, the first to make landfall on Hokkaido since 2016, swept across Japan's northernmost main island on Tuesday, 15th July 2025. The typhoon, which originally formed in the Pacific Ocean, moved away from the Sea of Okhotsk by Tuesday afternoon, but not before causing significant impact.
Wind speeds in Hokkaido, particularly in the city of Kushiro, reached up to 87.48 km/h, with coastal areas experiencing wind gusts of around 126 km/h. The Japan Meteorological Agency (JMA) had issued a warning for high waves along the Pacific coast of Hokkaido, advising residents to remain cautious.
Typhoon Nari brought heavy rainfall to Hokkaido, with up to 120 mm expected within a 24-hour period. The broader region, including Kanto-Koshin and Tohoku, also received high rainfall amounts, prompting local governments to issue evacuation advisories and warnings about landslides and flooding.
The storm transitioned to an extratropical cyclone later in the day, continuing its path towards the Pacific Ocean. Despite the JMA lifting the storm warning for Hokkaido, residents were advised to remain vigilant against both heavy rain and high waves.
The typhoon disrupted transportation services in Hokkaido and caused power outages in some areas. The government of Hokkaido has since initiated recovery efforts and damage assessments in affected regions. The total damage caused by Typhoon Nari in Hokkaido is yet to be assessed.

The environmental-science department at the Japan Meteorological Agency monitored the impact of Typhoon Nari on Hokkaido's weather conditions, marking a significant increase in wind speeds and rainfall. Due to the aggressive weather patterns caused by Typhoon Nari, various environmental-science observations, like wind speeds reaching up to 87.48 km/h and heavy rainfall up to 120 mm within 24 hours, were recorded.
