Boso Flower Line

The Boso Flower Line runs along the coastline at the southern edge of the Boso Peninsula. The road has no traffic lights between the Kenbutsu Crossing and Aihama Crossing, so frequently is used for road bike training. Furthermore, between Ito and Aihama, the road runs practically straight for the 6km. This section was chosen as one of “Japan’s best 100 roads.”
