A new genre of tourism is emerging: amateur archaeologists who enjoy viewing ancient burial mounds.
A mini music and dance festival at one such tumulus recently drew around 19,000 people.
"Come Come Hanicotto" was held in a 9-hectare park built around the Imashirozuka Kofun earthen mound in Takatsuki, Osaka Prefecture, in November. Musicians played and dancers performed, while shops sold sandwiches and souvenirs such as accessories shaped like burial mounds.
