The Oirase-Towada Utilization Council and the Oirase Gorge Ecotourism Project Executive Committee have been implementing private car traffic restrictions on the Oirase Gorge section of National Route 102 since 2003 to preserve the natural environment and alleviate traffic congestion.

This initiative is part of a social experiment with the future goal of transforming the entire gorge into a "Nature Museum" for visitors, especially with the upcoming opening of the Aobunayama Bypass. For the year 2026, the restrictions will be moved more than a month earlier than usual, from late October to the period of September 7th (Monday) to September 13th (Sunday).

Due to this significant change in scheduling, we urge all tourists and travel industry professionals to take careful note when planning trips and arranging vehicles.

Purpose and Background of the Schedule Change

This experiment aims to reduce the impact of vehicle exhaust on the trees by restricting traffic, thereby creating a safe and tranquil environment for pedestrians to enjoy nature. It also serves to test a sustainable tourism model that balances environmental preservation with appropriate use.

This year, the restrictions are set for early September to assess the optimization of the traffic environment during the 'early autumn Oirase' season, avoiding the peak congestion of the autumn foliage period.
