Masuda-no-Iwafone: The Ancient Rock Ship of Asuka, Japan | Mysterious Universe: "The largest of those monuments is known as Masuda-no-iwafune, which is said to mean Rock Ship of Masuda.  It sits atop the steep incline of a hill near Okadera Station and its purpose remains a mystery. 



The rock ship, being the largest of the mysterious rock mounds, is 11 meters (36 feet) by 8 meters (26 feet), by 4.5 meters high (15 feet), and is made of solid granite, which makes it somewhere around 80 tons as it sits.  It’s a carved mound, with two holes each about a meter square in the center, going through to the ground."
