(hereinafter, NEXCO CENTRAL) Tokyo Regional Head Office Hachioji Regional Head Office Large holiday period in September [5 days from Saturday, September 19, 2015 to Wednesday, September 23, 2015] Trends and countermeasures for traffic congestion (10 km or more) due to traffic concentration predicted to occur at Expressway etc. in the Kanto Koshin region and Shizuoka prefecture (including Tomei Expressway Toyokawa interchange in Aichi prefecture) We have compiled the above and will inform you.

In September of this year, we will have five consecutive holidays from Saturday, September 19 to Wednesday, September 23, so we expect that congestion will occur as much as this week's Golden Week.

Please refer to this traffic jam forecast to avoid peak traffic jams and adjust your departure times to help plan your trip. In addition, although it is predicted based on the past traffic jam record during the large holiday period in September and recent traffic conditions, the actual traffic condition may differ from the prediction due to accidents and weather. Please check the latest traffic information before departure.

Expressway companies provide traffic congestion forecast information and road traffic information using various tools. Please use it when using the Expressway.
