The Kanto Regional Head Office of East Nippon Expressway Co., Ltd. (NEXCO EAST) and the Tokyo Regional Head Office and Hachioji Regional Head Office of Central Nippon Expressway Company Limited (NEXCO CENTRAL) are pleased to announce the traffic congestion forecast (traffic congestion of 10km or more) for Expressway in the Kanto-Koshin region and Shizuoka Prefecture during the Golden Week period [12 days from Friday, April 25, 2025 to Tuesday, May 6, 2025]. If you are traveling during this period, please refer to the traffic congestion forecast and cooperate with spreading out your use of the roads.
Traffic congestion forecasts are based on past traffic congestion records and recent traffic conditions, but may differ from actual traffic conditions due to traffic disruptions such as accidents and weather, so please check the latest traffic information before leaving. Please note that holiday discounts will not be applied from April 26th (Sat) to May 6th (Tue).
◆Overview of traffic congestion prediction
- This year's weekday arrangement will be a "scattered holiday in the first half + four-day holiday in the second half" pattern, so we expect there will be a lot of traffic congestion in both directions during the second half of the four-day holiday.
- Because the first half of this year includes weekdays, leisure demand is expected to be lower than last year's three-day weekend, and traffic jams longer than 30km are expected to decrease on many routes. However, on routes such as the Tomei Expressway, which has a lot of business traffic, traffic jams longer than 10km are expected to increase, especially in In-bound direction.
