Japan is gearing up for its year-end holiday travel season, with transportation authorities forecasting significant traffic congestion on expressways nationwide. From December 27, 2024, to January 5, 2025, the expected number of traffic jams exceeding 10 kilometers is set to rise markedly compared to the previous year, indicating travelers should prepare for delays.
According to NEXCO East Japan, NEXCO Central Japan, and NEXCO West Japan, during this peak travel period, congested conditions are anticipated with 242 instances of traffic jams of more than 10 kilometers occurring on the expressways, up from last year’s figures which saw 166 such congestions. This increase highlights the growing trend of holiday travel as people venture out to reunite with families or partake in New Year celebrations.
The busiest days for southbound traffic are predicted to be December 28 to 30 and January 2 and 3, causing extra pressure on major routes. On the other hand, northbound traffic jams are expected on January 2 to January 4. Among the highways expected to see the longest delays are the Tohoku Expressway and the Kanetsu Expressway, which could experience standstills of 35 kilometers at peak times.
Particularly troublesome sections include:
- Tohoku Expressway (southbound) near Hanyu PA on January 2, expected 25 km congestion
- Kanetsu Expressway (southbound) at Takasaki SA on January 2, expected 20 km congestion
- Tohoku Expressway (northbound) at Kazo IC on January 3, expected 35 km congestion
- Kanetsu Expressway (northbound) at Takasaki SA on January 2-3, expected 30 km congestion
- Tomei Expressway (southbound) at Ayase SIC on multiple days, expected 25 km congestion
Travelers heading to and from major urban centers should be especially cautious, as traffic peaks are likely to overwhelm these routes with holiday travelers. The authorities also warn of deteriorated weather conditions across the nation. A winter storm is forecast, particularly affecting the Niigata region with heavy snowfall expected.
For example, the Niigata Prefectural Government has advised residents to remain vigilant, particularly on expressways which could face closures due to snow accumulation. Certain sections of the expressway system may become impassable should the snow become severe enough. Authorities have warned travelers to check weather updates and road conditions before making their journeys to avoid the risk of being caught unexpectedly.
On December 22, for example, potential road closures due to snowfall were communicated, with the worst anticipated from nighttime through early morning hours. The Expressway Route between Yuzawa IC and Muikamachi IC is under special scrutiny, with these areas listed as having the highest probability of being shut down during bad weather.
Train services will also experience interruptions due to heavy snow predicted along specific rail lines. JR West Japan has announced changes to its operations, especially affecting the Oito Line, as trains will not operate on December 22 due to adverse conditions. Passengers are recommended to stay updated with the latest announcements to avoid disruption.
This year’s forecasts are significantly higher than prior travel seasons and raise concerns about safety amid increased road usage coupled with harsh winter weather. The Japanese Highway Traffic Information Center has urged all travelers to prepare effectively, adopting cautious driving practices and ensuring their vehicles are suitable for winter travel, particularly if traveling on routes prone to heavy snowfall.
Key authorities urge individuals planning to travel during this year-end period to stay informed on the latest traffic and weather conditions from the NEXCO websites. Temporary lane closures and potential detours could arise as authorities work to manage the inevitable congestion wisely and maintain safety across the road networks.
Clearly, this holiday season promises both excitement for family gatherings and headaches for travelers. The combination of increased traffic and poor weather conditions will test those venturing out. Whether driving to visit family or heading off on vacation, awareness of these conditions is your best strategy to minimize frustration and travel safely.
