At Fuji Subaru line, you can hear the first part of the Fuji no Yama song on the ascending drive up to Mt. Fuji, and the second part of the song on the descending drive down form Mt. Fuji.
You might wonder how did they make it. Well, the answer to that lies on road itself. When you look at it closely, the melody road is made with lines all over the road. These lines are the one produced the sound. If you look closely to the pictures, the lines make some gap on the road. When the car's wheels go through these lines, it produces sound. The gaps of the line was adjust so that it produces the right tone for the song. The closer the gap, the higher the pitch of the sound, and the wider the gap, the lower the pitch of the sound.
