... as you drive over them
By Helena Asprou, ClassicFM
Known to Japanese locals as ‘Melody Roads’, these harmonious highways play music to drivers as they travel around the country. But it’s not just for entertainment...
If you ever find yourself taking a scenic trip around , keep an eye (and ear) out for these music-playing roads.

The will only play at the if people are driving at the set speed limit, encouraging them to travel safely and at a steady pace.
The music is also intended to alert tired , stopping them from falling asleep at the wheel and decreasing the number of car accidents in the area.

There are several hit songs for you to enjoy – from ‘Shiretoko Ryojo’, found on a regional road in Shibetsu, and ‘Country Road (Studio Ghibli’s Whispers of the Heart)’ on Kaneyama’s National Route 252, to ‘Fuji no Yama’ on the Ashinoko Skyline.
And it seems tourists are already impressed with the concept, sharing their videos on social media:

There are grooves, which are cut at specific intervals in the surface. When you drive over those small markings, you can emit a rumbling tone throughout a vehicle.
