Foreign residents across Japan are facing significant transportation disruptions as heavy snowfall blankets multiple regions during the peak New Year holiday travel period, creating challenging conditions for those returning from holiday destinations.

According to NHK reports, a strong winter pressure system combined with cold air masses has brought heavy snow to the Sea of Japan side of the Chugoku region, Hokuriku area, and unusually, accumulation in Tokyo's central districts and other Kanto plain areas. The Japan Meteorological Agency confirmed Tokyo's first snowfall of the season at 6:55 PM on January 2nd, arriving one day earlier than average but 14 days later than last season.

The timing has proven particularly problematic, coinciding with the traditional U-turn rush as millions of people return home after spending the New Year holiday period with family or at vacation destinations. Rail services, flights, and expressways are experiencing congestion from the morning hours, with weather conditions compounding the usual holiday travel delays.

Major highway disruptions have been reported, with the Sanyo Expressway experiencing severe impacts. Multiple vehicles became stranded due to snow conditions, creating traffic jams extending over 20 kilometers on the upbound lanes between Hiroshima and Yamaguchi prefectures. This represents a significant delay for travelers, potentially adding several hours to journey times on what is normally a heavily-traveled route.

Meteorologists warn that eastern and western Japan will continue experiencing heavy snowfall through January 3rd, particularly in mountainous areas. However, the unusual aspect of this weather system is its impact on Pacific-side flatlands that typically see little snow accumulation. This has caught many residents and travelers unprepared, as these areas often lack the snow removal infrastructure common in traditionally snowy regions.

The morning of January 3rd brought severe cold temperatures across widespread areas, raising concerns about road surface freezing even in locations where snow has stopped falling. Black ice—a thin, nearly invisible layer of ice on roadways—poses particular danger to drivers unfamiliar with winter driving conditions. Transportation authorities are urging extreme caution regarding both snow accumulation and frozen road surfaces.

For foreign residents, several practical considerations emerge from these conditions. First, those planning to travel should check transportation service status before departing, as delays and cancellations are likely to continue. Railway companies and airlines typically post updates on their websites and social media channels in multiple languages during severe weather events.

Second, residents in affected areas should prepare for potential disruptions to daily life. This includes stocking essential supplies, as snow can make shopping trips difficult and may delay delivery services. Those living in apartments should also be mindful of shared spaces, clearing snow from entrances and walkways when possible to prevent accidents.

Third, driving requires special attention. If travel by car is necessary, vehicles should be equipped with appropriate tires—either studless winter tires or chains. Japanese law requires adequate tire equipment in snowy conditions, and police conduct roadside checks. Drivers without proper equipment may be turned back or face penalties.

The meteorological agency continues monitoring the situation, with forecasters providing regular updates through television broadcasts, weather websites, and the JMA's multilingual website. Foreign residents can access weather warnings and advisories in English and other languages through these official channels.

As Japan's winter season progresses, this early snowfall serves as a reminder for foreign residents to prepare for winter weather conditions, even in regions where heavy snow is uncommon. Understanding local weather patterns, transportation protocols during snow events, and basic winter safety measures will help ensure a safer, less stressful experience during Japan's winter months.
