A strong cold air mass is moving over Japan, bringing heavy snowfall to the Sea of Japan coastline from January 1st through January 5th, 2026. According to weather reports, the snowfall is expected to be most intense on Friday, January 2nd, potentially causing significant travel disruptions during the peak New Year holiday return period.
Why This Matters for Travelers
This weather event coincides with the “U-turn rush,” when many people travel back to major cities after visiting their hometowns for the New Year holiday. Travelers, especially those on short-term visits, should anticipate potential delays and cancellations.
The conditions will likely affect:
•Transportation: Shinkansen, local trains, flights, and highway buses are all at risk of service disruptions.
•Regions: The most affected areas are along the Sea of Japan, including Hokkaido, Tohoku, Hokuriku, northern Kinki, and the San’in region.
•Road Travel: Even areas that rarely see snow, such as the Pacific side of Western Japan and parts of Kyushu, may experience frozen and icy roads.
Location & Context
•Primary Affected Zone: The entire Sea of Japan coast, from Hokkaido in the north down to the San’in region (Tottori and Shimane prefectures) in the west.
•Specific Areas of Concern: Mountainous areas in the Hokuriku region (Niigata, Toyama, Ishikawa, Fukui) and northern Kansai could see particularly heavy accumulations.
•Atmosphere: Travelers should be prepared for crowded stations and potential last-minute schedule changes.
Dates & Timing
•Main Period: Thursday, January 1, to Monday, January 5, 2026.
•Peak Snowfall: Expected all day on Friday, January 2.
•Lingering Effects: Snow and strong winds may continue on the Sea of Japan side from Hokuriku northward into Saturday, January 3. Snowfall is expected to continue increasing in mountain areas through January 5.
Access Information
