Imamachi Ichirizuka
Japan
The Imamachi Ichirizuka is a historic Japanese distance marker akin to a milestone, comprising a pair of earthen mounds located in what is now the Imamachi and Umekita neighborhoods of the city of Miyakonojō, Miyazaki Prefecture in Kyushu, Japan. It was designated a National Historic Site of Japan in 1935, with the area under protection expanded in 1973 to include a surviving portion of the tree-lined road.
