Tawarayama Tunnel

Tawarayama Tunnel is a mountain passage in Kumamoto Prefecture that connects different regions through the surrounding hills. It features modern lighting systems and is designed for continuous vehicle traffic throughout the day and night.

The tunnel was built to create a vital transportation link across challenging mountain terrain. The project marked an important advance in regional transport infrastructure for the prefecture.

The tunnel represents Japanese engineering excellence and serves as a testament to the determination of local communities to overcome geographical barriers through infrastructure.

Travelers can reach this passage via main roads from Misato town or from Kumamoto City. Parking areas are available near the tunnel entrances for those who wish to stop.

The passage includes special safety measures designed to protect against rockfall from the steep surrounding hills. This engineering solution shows how infrastructure in mountain regions manages natural hazards.
