2019.06.13 Road and access route restrictions during the G20 Summit
With the G20 Summit taking place in Osaka from June 27 through June 30, access routes in and around Osaka and Kobe will be affected. Large-scale and long-lasting restrictions will apply to the express ways and regular roads. This will affect access to both cities, their surrounding airports and other major transport hubs in the area.
As trains are likely to be the least effected, travelling via train where possible is recommended, as well as checking access routes and their restrictions before planning your trip to Kobe during the G20 Summit.
