 Hokkaido is home to one of Japan's three Melody Roads, which is made from grooves cut into the ground, which when driven over causes a tactile vibration and audible rumbling transmitted through the wheels into the car body.The coal railways were constructed around Sapporo and Horonai during the late 19th century, as advised by American engineer Joseph Crawford.The Hokkaido Prefectural Board of Education oversees public schools (except colleges and universities) in Hokkaido.
